A quick guide to small 3 phase motor

Everything around is surrounded by electric motors due to technological advancement. We cannot imagine our daily tasks without the help of machinery. Three-phase electric motors are the most widely consumed electric motors in both domestic and commercial sectors.

The latest report by Fortune Business claims that the Electric Motor market is projected to grow from USD 113.14 billion in 2021 to USD 181.89 billion by 2028, and three-phase motors hold the significant market. 

But have you ever heard of a small 3 phase motor? It is a compact type of three-phase motor that have different functionalities and application range. In this article, we will briefly cover all the important things you must know about a small three-phase electric motor, its working, types, and different applications. 

So, without wasting any time, let’s get started.

What is a small 3 phase motor?

A small three phase motor is a type of electric motor that operates on a 3-phase power supply. The structure and working mechanism of a small three-phase motor is quite similar to a typical 3-phase motor. However, the main difference between these two motors is their application.

Usually, 3-phase electric motors are used for higher industrial application where high power and precision is required. On the contrary, small three-phase motors have smaller sizes; thus, ideal for applications ranging from a few watts to kilowatts.

Small 3-phase electric motors are as efficient as industrial three-phase electric motors, where the efficiency rate ranges from 75% to 95%. These motors are also employed for micro commercial application where high rotational force and output power is demanded.

Based on the output power, three-phase motors are typically available in the market as;

Different types of small 3 phase motors:

Small three-phase motors have different types based on their specifications, capabilities, and characteristics. Following are the different types of small three phase motors you can find in the market;

  • Synchronous Motors
  • Induction Motors
  • Stepper Motors 
  • Servo Motors
  • Brushless DC Motors

All of the above-listed electric motors have a wide range of industrial applications due to their reliability, output power rating, and longevity. 

How does a small 3 phase motor work?

Figure 2: Working of three-phase motors

The working principle of a small 3-phase motor is identical to the mediocre three-phase motors. It takes power from alternating current (AC) and drives the motor by producing magnetic fields. Once the small three-phase motor is connected to the power source, it starts generating a rotating magnetic in the stator winding, enabling the rotor to rotate. 

The rotor’s movement drives the motor shaft and performs mechanical operations. These motors have less complex design and housing than industrial-standard 3 phase motors. Moreover, they are cost-effective and work for an extended period without high maintenance.  

If your application demands speed, frequency, and voltage control, you can use a VFD (Variable Frequency Drive). It is a common electronic device used to modify the speed, power, and frequency of an electric motor.

Advantages of small 3 phase motors:

You must have heard of the extraordinary features and usage accessibility of three-phase electric motors. However, these motors have diverse advantages and perks, which makes them more convenient and effective than single-phase electric motors.

Here are some noticeable advantages of small three-phase electric motors;

  • They have a smaller footprint and compact construction.
  • Small three-phase motors require less space for installation; thus, they are suitable for compact space applications.
  • They produce less noise and vibrations, ensuring quieter and smoother operation. 
  • Small three-phase motors provide high power density while being lightweight.
  • These motors are designed to provide the same level of efficiency and output power.
  • Compact 3-phase motors demand less maintenance and repair due to high-quality and precise design. 
  • They are easily controlled by VFD drives for precise machinery operations. 

What are the main applications of a small 3 phase motor?

Small three-phase motors are employed in domestic and small-scale machinery. Here are some main applications of small 3-phase motors in domestic and commercial industries;

    • HVAC Systems: According to the latest report, currently the automotive HVAC market is valued at USD 53.78 billion and will be growing at a CAGR of 6.39%. The heating, ventilation, and air-conditioning system is the biggest sector to use small 3-phase motors due to less space and durable performance. 
    • Electric Vehicles: Small 3-phase motors have major applications in electric vehicles. They are used to control the speed, frequency, and RMF of electric motors. 
  • Conveyors and Belts: Small 3 phase electric motors are used to drive small conveyors and belts due to high efficiency and simpler design. 
  • Domestic Appliances: Domestic appliances such as mixers, grinders, fans, and toys that demand continuous rotations use small three-phase motors instead of single-phase motors. 
  • Pumps: Another common example of a small three-phase motor application is pumps. Due to the close-packed structure and low torque rating, these motors are used to drive small pumps.
