1. What are 3 phase electric motors?
Three-phase motors are called asynchronous or an induction motors. It’s an electromechanical device that transforms electrical energy into mechanical energy. Three ACs of the same frequency make a three-phase power source that helps to work this motor.
Single-phase motors aren’t widely used in industrial settings as the three-phase option because it’s featured in home appliances like fridge, vacuum, and so on. Electromagnetic interactions are used for converting into mechanical energy.
Often known as self-starting motors, 3 phase electric motors are simple and reliable with a long lifespan. The speed of the 3 phase electric motor can range from 900 to 3600 RPM and 300 KW. You’ll find such a motor in a squirrel cage or with slip rings based on your needs.Read more……
2. How do three-phase electric motors work?
Faraday’s law or the principle of electromagnetic induction governs the working of the 3 phase electric motors today. These motors are constructed to work via a three-phase alternating current.
In an induction motor, coils inside create a magnetic field that changes position with oscillating AC that leads to the stator making the rotating magnetic field. The changing magnetism from the stator brings a current into the rotor coils of the motor that leads to an opposite magnetic force from the rotor.
When the rotor field tries to align the polarity with respect to the stator field, you get a net torque that when linked to the rotor shaft creates rotations to create alignment. The three-phase windings of the motor when linked to AC creates a rotating magnetic field. Windings have a 30% overlap with a specific number of poles based on the speed you’re aiming for.
3. What size electric motor do I need?
At Xinnuo, there are three electric motors in different configurations that you can order at wholesale prices right away. Take a look at it below.
- Y2 63-355 Series motors are designed with a hard frame for durability and fan cooling for efficiency. These motors have a motor housing in a Cast Iron frame and power range up to 355 kW. It’s good for pumps, fans, and other food as well as agricultural machinery.
- YC 80-132 Series type of motors are fan-cooled motors with complete enclosing and cast iron framing with heavy-duty elements. The three-phase induction motor with 80 to 90% power factor during full operating strength.
- MS 63-160 Series in Aluminum frame are the newest innovation in the world of motors. Adhering to IEC regulations, this motor makes very little noise and vibration with a sturdy construction.
4. What are the main parts of an electric motor?
The design and construction of Electric Motors can be different. It works by transforming electrical energy into mechanical energy using several important parts as shown below.
- Rotor: The moving part on the electrical motor, rotor sends power to machinery by the turn of the shaft. Rotor combines with the stator to carry current that moves the shaft eventually.
- Stator: The drive that moves the rotating part in the motor is created by the stator. They’re constructed with lining made of metal instead of total metalcore to reduce loss of energy.
- Terminal box: When the leads of the motor are connected to the leads of the power supply, it’s called a terminal box. The main function of such a box is to secure and terminate wires. It doesn’t terminate just one wire but many on a long single strip.
- Capacitor: Also called a start capacitor is one that regulates power to one or more winding fields. It provides a higher starting torque to enhance the motor efficiency and running capacity.
- Flange cover: It’s a protection technique for the internal wirings of the motor. It covers the face and the outer body in its entirety. It has a larger diameter than the motor itself.
- Foot: In the category of foot-mounted motors, the foot has to be kept even for the smooth running of the electrical motor.
- Fan: The fan wheel of the shaft in an asynchronous 3 phase electric motor forces airflow to regulate the temperature of the main functions.
- Fan cover: Such a prop pushes the airflow near the surface to cool down the area and clean the ribs of the motor. That’s why you’ll notice an air gap between the fan cover and the subsequent ribs.
5. What type of products does Xinnuo offer?
In the past two decades of our experience catering to the electrical industry, Xinnuo has produced scores of generic and custom motors for our clients across the world.
Here’s a list of our stock of products at present:
- Ordinary motor: This is a standard motor that converts electric energy into mechanical energy. It has a 70% to 95% of electricity conversion rate and 30% to 5% loss due to mechanical loss. It’s created to be dustproof and waterproof with low energy use, noise, and vibration as well as a long lifespan.
- Russia Motor GOST Standard: Made for the Russian demographic, the GOST Standard Motor is ideal for the replacement of machinery in plants based on Soviet engineering. These are low-voltage electric motors with excellent energy savings in industrial settings.
- Speed regulating motor: A variable frequency motor, this is a three-phase asynchronous motor typically in cast iron. The electromagnetic motor is in the YVF2/YVP category on Xinnuo.
- Two-speed motor: Common as the dual or Dahlander motor, this is a multi speed motor in the induction category where the speed is regulated by varying the total poles by tweaking the wiring inside.
- Inverter motor: At Xinnuo, we have the AC induction inverter motor that’s lightweight with heat resistance in the YL series.
6. What are the factors that affect the efficiency of the 3 phase electric motors?
With 90% to 95% efficiency, three-phase induction motors are reliable. When it comes to efficiency, it depends on the material. If it’s a cold-rolled sheet, the efficiency of the 3 phase electric motor will be high and strip steel lowers the efficiency.
Apart from that, the mechanical and electrical flaws within the motor can make it inefficient. Resistance loss alone can add up to 15 percent loss. Residual losses are typically accrued from other parameters.
Typically, the efficiency of a 3 phase electric motor is affected by the starting foot, less wearing parts, single capacitor, centrifugal switch, and a terminal box.
7. How do you increase the speed of an AC motor?
One thing to keep in mind while increasing the speed of an AC motor is how you keep the volt to hertz ratio a constant without which, the windings heat up. When you double the motor base speed from supposed 50 Hz or 1500 rpm, the frequency will rise to 100 Hz, thereby doubling the speed.
Hence, by heightening the input frequency of the motor, it’s possible to increase the total speed. Even most of the small AC motors can be bumped up to 73% in speed. A variable frequency drive can do this. Don’t overdo the frequency spike as anything around 25% is fine but 50% isn’t.
8. What materials does XINNUO use To Produce three-phase Motors? Do you use 100% copper?
Yes, Xinnuo Motor uses 100% pure copper to create our 3 phase electric motors by wounding it into the armature. Materials used by Xinnuo to produce top-notch motors are given below:
- W800 Cold Rolled Steel Stator is electrical steel with negligible iron damage, good permeability, and high magnetic sensitivity. The smooth surface makes it a perfect win.
- Pure Copper is used in the Xinnuo range of motors for its high conductivity. It features ith coil windings, connectors, and bearings.
- C&U bearing or Construction & Use bearing for original equipment manufacturing are great for their versatility. C&U bearings guarantee a superb speed and flawless operation.
9. How to troubleshoot a three-phase motor?
If you’ve tried all the standard troubleshooting methods as advised by technicians, the next step is to get in touch with the manufacturer right away. We suggest you go to our Contact Us page and send your inquiry via the form. Alternatively, you can reconnect with the Xinnuo Motor sales representative who assisted you while placing the order or during after-sales services.
For basic troubleshooting, take a look at the list of options below.
- Check for the voltage and compare it with the manufacturer’s specifications on all three phases.
- Repair loose connections after disconnecting the motor.
- Look out for overheating or burnt smells.
- Clean the motor and vacuum the parts.
- When there’s a blown fuse, replace it.
- Reset overload if the overload trips.
- Crosscheck if the power supply meets the indications on the nameplate of the motor.
- Check lubrication and bearings if there’s a mechanical failure.
- Use a test lamp to identify poor connections when the stator coil connections fail.
- Reduce load if the motor overheats and open vent holes.
- Realign, balance coupling, or replace bearing if the motor vibrates too much or makes too much noise.
- Replace or straighten out the shaft when the bearings are hot. You can also decrease belt tension, use bigger pulleys, and correct realignment of the drive, in such a case.
10. What are the advantages of 3 phase electric motors?
Unlike a single-phase motor, a three-phase is more reliable and trustworthy. Let’s look at why.
- Power: While power pulsates in a single-phase setup, the 3 phase electric motor delivers constant power. It’s 1.5x more than the single-phase option. Three-phase motors generally run on machines with a horsepower of higher than 7.5.
- Output: At its size comparable to other motors, the output is higher for a 3 phase electric motor.
- Efficiency: While single-phase motors need auxiliary for starting up, three-phase is self-starting. Moreover, it uses very less conductor material.
- Torque: You won’t find the torque pulsating here as you see in the single-phase motor.
- Flexibility: Three-phase motors are crucial for their pliable power density.
- Cost-efficient: Unlike the single-phase option, huge volumes of electricity can be used at low costs with a three-phase option.
- Harsh conditions: 3 phase electric motors fare well in unfavorable conditions like marine vessels.
- Compatibilities: Gearbox and speed compatibilities make it ideal for high and low speeds.
11. What’s the difference between AC and DC motors?
The core difference between the two has to do with the power supply.
While one uses alternating current, the other direct current. DC series motor can run on AC supply but not vice-versa. The former also comes with commutators and brushes. However, AC can run on both power supplies (single-phase and three-phase) and DC only single-phase.
DC motors are self-starting, but only a three-phase AC motor can do the same. Armature works opposite in both AC and DC but AC has three input terminals and DC two. It’s true that DC has better efficiency, but the lifespan of this motor is low. On the other hand, an AC motor produces less heat and works great in the commercial sector.
There are several types of DC motors like shunt-wound, separately excited, series-wound, compound motor, and AC has numerous ones based on speed, input power phase, and rotor type.
AC motors are inevitable when you need high speed while DC when needing high torque. If you want to see DC current in action, check out your home appliances and AC when considering industrial electronic machinery.
12. What’s the lifespan of electric motors?
Electric motors have a good expiry date of five to ten years in use. It can go longer or shorter based on the setting it’s kept in, such as the concerning climate. Dust to moisture and dirt can ruin it without impractically regular cleaning.
13. What determines the RPM of an electric motor?
When you’re talking about the rotational speed of this type of motor, you need to look at its poles and the voltage supply frequency. The speed of electric motors is determined based on the specific application just as how horsepower is determined by mechanical energy.
RPM refers to revolutions per minute. The equation here is rpm = 60 x f/pairs of poles= 60 x f/ (poles/2)= 120 x f/ poles.
The following will help you how it’s affected in numbers.
With a two-pole motor at 50 Hz, the speed will be 3000 rpm. For a four-pole motor, this is 1500 rpm and 1,000 rpm for a six-pole motor at the same frequency. At eight poles come 750 rpm and 600 rpm at ten poles.
With a two-pole motor at 60 Hz, the speed will be 3600 rpm and 1800 rpm for a four-pole motor. It goes down to 1200 rpm for six poles, 900 rpm for eight poles, and 720 rpm for ten poles at the same frequency.
14. How do I choose an electric motor?
First off, you need to pick the type of motor from the three main categories such as AC asynchronous motor (may be single-phase or three-phase), synchronous motor (DC), or the stepper motor.
For taking a good decision, you must consider the reason for using the motor. If your goal is dynamic, the synchronous motor is a must but for precision in positioning, nothing beats the stepper motor.
The next step is to decide on a size, followed by the technical specs such as the power, speed, and torque of the motor. To decide on the size, weigh in on where you want to situate it and the space it’s permitted to take.
The atmosphere to keep it will help you decide on what material to pick for the motor. From damp to explosive, hot, and several other options are there based on the environment the motor will sit in. Finally, the energy your motor can serve also helps you select the right one.
You must also keep a close eye on the input power source besides the power supply of the motor. Choosing between AC and DC is easy once you know what you’re using the motor for. Put simply, DC is good for steel mill equipment (rolling) while AC works for irrigation pumps, AC compressors, etcetera.
Also, consider the horsepower and speed of the motor so that it delivers on your needs. Motor frame and mounting positions are a must-check too before ordering electric motors directly from a manufacturer.
15. How are AC motors manufactured?
With two main rotors inside and outside, AC motors are made from a Yoke (Frame), Stator, Rotor, Fan, Slip Rings, and shaft. The frame protects from environmental damages and housing for inside parts. Stator window housing is enclosed in a stable environment with the bearings offering appropriate friction for it to run sans problems.
Ring of electromagnets outside arranged to create a rotating magnetic field and fan inside the motor reduces the heat by using the ventilation within. The shaft of the motor is made to provide mechanical energy due to the rotation of the rotor. The slip rings here to ensure the AC power changes as required in the coils of the motor.
16. How is a motor controlled?
A motor is typically controlled by a controller that includes one or more devices. The controller can move the motor into reverse or forward movements. There are two ways of controlling a motor.
In the wiring technique, the forward and reverse movements are controlled by you. On the other hand, you can also set up an external controller to start as well as control reverse and forward movements. However, the controller can begin from a small voltage and regulate higher values for large motors.
17. How to connect a three-phase motor?
Connecting a motor is engineering work. The 3 phase electric motor first off needs a three-phase power mode.
Typically, there are wiring diagrams that can guide while connecting a 3 phase electric motor. Once you’re done, all you need to do is open the junction box to access the wire. You can identify the wires by numbers or colors inside the motor or you can access the nameplate to get details about the wiring of the motor.
Wye wiring and delta wiring for this type of motor is the best possible methods.
18. Can a 3 phase electric motor run on 230 volts?
While a 3 phase electric motor is created for running on an industrial power supply, it can run on the household voltage of 230 too. To do so, you need a single to three-phase VFD so as to remove the inrush power when you start the motor.
Running 3 phase electric motors on a single-phase power supply requires you to wire the single-phase power onto the variable frequency drive. Finally, wire the three-phase power of the motor to the output side, and you’re done.
19. What are the various types of electric motors?
One of the most advanced motors today for industrial and residential uses is the electric motors. There are two main types: AC and DC.
- AC Brushless motors use the induction of the rotating magnetic field inside the stator to turn the rotor and stator in a synchronous manner.
- DC Brushless motors are ideal for performance in a limited space. Smaller than AC motors, these also have embedded controllers for operating smoothly when there isn’t any slip ring.
- DC Brushed motors are fitted with commutators. Here, the orientation of the brush decides the flow of current.
- Direct Drive is a highly efficient motor with a long lifespan. It can displace servo motors and their transmission besides ensuring easy maintenance. They also achieve quick acceleration.
- Servo Motors are fitted with feedback sensors that are ideal and almost inevitable for fields like robotics. DC brushed motors or brushless AC motors are used for this purpose.
- Linear Motors use unrolled stator and rotor to create linear force based on the length of the device. With two ends having flat sections that are active, linear motors are accurate and faster than other types.
- Stepper Motors work with an internal motor and are tweaked electronically using magnets with the rotor being made of soft metal or permanent magnets.
- DC Shunt Motors come with high speed and consistent torques.
- DC Series motors have a great low-speed torque with limited high-speed torque.
- PMDC motors use permanent magnets and are brushed with cheaper manufacturing costs.
20. What materials do you need to make an industrial motor?
For industrial motors, the basic choices include powder metal or electrical steel. You’ll need cast iron or fabricated material for the structure, conducting material such as copper or aluminum, a magnetic component such as iron, insulation.
AC and DC motors have differing frames where one is unique from the core and the other joined.
21. What Should I Know Before Ordering electric motors?

Application and Uses
34. What are Common Applications of 3 Phase Electric motors?
Electric motors like a three-phase motor from Xinnuo can be used for many things. In fact, 80% of motors in industrial settings are three-phase. It’s featured in pumps, air compressors, lathe machines, conveyors, grinding machines, flour mills, pressing machines, and even steel mills, lifts, crane machines, line shafts, and crane machines.
Crushers, hoists, large industrial grade fans, oil mills, huge exhaust fans, and the textile industry also use 3 phase electric motors. Centrifugal pumps, milling machines, woodworking machines, huge blowers, lathe machines, and similar industrial equipment uses 3 phase electric motors.
While single-phase motors are used in domestic settings like an electric shaver, small fan, mixer, juicer, motorized toys, vacuum cleaners, and drilling machines, three-phase has other uses.
35. Are nameplate ratings correct with respect to your order?
Once you receive the item you’ve ordered, check whether the ratings on the nameplate are correct. The nameplate of the motor shows frequency, voltage, full-load amps, full-load speed, phase, time rating, horsepower, and insulation class. Make sure it matches with the specs you’d requested.
36. Can you ensure identical color and dimension requests as per order?
Crosscheck the color and size of the motor based on what you’d requested. If it doesn’t match, raise a request with the manufacturer to get the modifications completed for the same. With the difference in color and dimensions, the entire configuration of the motor can change. Along with this, you should also know the weight of the motor.
37. Are there damages or visible flaws?
The final check is the exterior inspection. Look out if you notice any damages such as scratches, chipping off of color, and any other defects. Visible flaws are a sign that the quality of the motor may be compromised. Also, assess the working of the motor by calibrating startup up to noise and functionality.
38. Do you know how to store the motor in optimum conditions?
To ensure your motor lifespan remains at its maximum power, you must store and maintain it in the right setting. For starters, a dry environment is a must for preventing corrosion to the sensitive parts of the motor.
39. Have you removed the transit clamps that prevent the rotating parts of the motor from moving?
Before using the motor, also make sure you’ve removed all the props that came with the motor to prevent it from moving during transit such as the transit clamps. These are added to prevent the motor parts from moving when in transit.
Before mounting the motor, make sure the nearby areas are thoroughly cleaned off dust, dirt, and grime. The motor shaft should be properly aligned with the driven shaft.
40. How to clean the interior and exterior of the motor?
Keeping a motor in its top quality requires many efforts including cleaning. You can clean the motor in-between use after it has been operating for some time.
Take a look at our stepwise guide to do so below for both interior and exterior of the motor.
On motors that are open-ventilated, louvers, screens as well as inlet openings mustn’t ever accumulate dirt and grime. If you notice any, it has to be cleaned even more regularly. Always switch off the motor well before starting any cleaning activity.
- Air filters must be cleaned, reconditioned, or changed based on their condition. If your air filter is a permanent one, freshwater is all you need to clean it. Make sure to dry it well before installation.
- If you’ve enclosed motors, you should start by cleaning the external fan because sediment dirt can lead to imbalance.
- Tubes within the air-to-air heat exchanging setup should be cleaned with a tube brush using a brush with fiber bristles.
- Dirt can create an insulation blanket that makes the motor overheat sporadically and thus reducing the lifespan of the motor. You can clean it by scraping and dry ice blasting.
- When you’re using compressed air for cleaning, the used air shouldn’t contain any moisture. Keep the air pressure lesser than 4 kgcm2.
- Vacuum cleaning is ideal before and after other types of cleaning as it can remove contamination on the surface that’s loose without scattering it about. Make sure vacuuming is non-metallic for preventing winding damages.
- Winding dirt can be removed with a soft cloth to wipe down. For oily contamination, a wet soft cloth can be used.
- A 10-degree-celsius temperature hike is commonly observed before and after cleaning.
Maintenance of a 3 phase electric motor also involves measuring insulin resistance while the comprehensive plan includes replacements and repairs on top of cleaning.
