2. How Many Amps Does A 1 Horsepower 3 Phase Motor Draw?

1 hp 3 phase motor amps rating is 1.83 amps on full load; however, 1hp single phase motors draw 16 amps on full load. That is why 1 hp 3 phase motors are more efficient than single phase motors. The efficiency rate of 1 hp three phase motors is 73% to 75% making them suitable for low-speed industrial purposes.

3. What Are Common Applications Of 1 Horsepower 3 Phase Motor?

The general applications of 1 hp three phase motors are discussed below.

 Let’s have a look,

  • Domestic appliances 
  • Industrial equipment 
  • Machining tools and Gear box
  • Automation industry
  • Compressors and Pumps
  • Mining industry
4. How Many KW Is A 1 HP 3 Phase Electric Motor?

1 hp motors are 0.75 Kw, and have 1440 rpm value (revolution per minute). This feature ensures accurate performance with controlled speed. These motors are low power consumption, which makes them affordable and reliable.

5. How To Extend The Lifespan Of A 1 HP 3 Phase Electric Motor?

Although 1 hp three phase motors are long-lasting, you can increase the lifespan of 1 hp motors with regular checking and care. Here are some of the important tips to extend the life of your 1 hp 3 phase motor:

  • Regularly check the leakage and temperature of the motor to avoid sparks and damage. 
  • Overheating is the primary cause behind the early failure of 1 hp motors. Avoiding frequent supply voltage changes reduces overheating in the winding.
  • Monitor external conditions like moisture, heat, water, and grease to ensure the long life of 1 hp motors.
  • Check the proper positioning of the motor to extend the operational capacity and lifespan of the 1 horsepower 3 phase motor.
6. Does The 1 HP 3 Phase Electric Motor Demands Capacitor?

No, the 1 horsepower 3 phase motor is self-starting which does not demand additional power supply. These motors generate high initial torque without external support. Unlike 1 hp single phase motors, they induce current with capacitor’s starting rotations. They run through the rotating rmf produced in the stator winding.

7. What Is The Working Principle Of A 1 HP 3 Phase Motor?

The working mechanism of a 1 horsepower 3-phase motor is based on the phenomenon of electromagnetic induction. In electromagnetic induction, there is a difference between the relative speed of the stator and rotor that induces a current. The relative difference between the speed of the rotor and stator is called slip. The motor gets excited when connected to the current supply. The stator winding produces magnetic fields, which influence the rotor to rotate at a constant speed. Thus the rotor moves in the direction of the stator’s magnetic fields. The rotor has slots slightly parallel to the shaft that induces a current in it. The shaft carries current to the load and utilizes it for the final application.

8. What Is The Price Difference Between 1 HP (Three Phase) And 1 HP (Single Phase) Motor?

The cost value is one of the valuable perks of a single phase 1 horsepower motor. Another common dissimilarity of 1 hp single phase and 1 hp 3 phase motor is price range. The 1 hp single phase motors are cost-effective. These are the perfect choice for low-budget customers. 

On contrary, the 1 horsepower three phase motors are a bit pricy because of their various significant features (e.g. frame size, speed, and PF rating). Although these motors are more expensive than single phase 1 hp motors, consumers prefer 1 hp three phase motors because of their wide range of applications in different commercial sectors.  

9. What Are Some Significant Benefits Of 1 HP 3 Phase Motor?

1hp 3 phase electric motors are very popular because of their exceptional features. Let’s uncover some significant features and general specifications of 1 hp three phase motors.

Operational capacity:

The operational capacity of a 1 hp 3 phase electric motor is high because these motors work on a three-phase power supply. These motors are connected to the star or delta configuration, which increases the working capacity of these motors.

Low Noise and Vibration:

Less noisy and low vibrating machinery lasts long. Therefore, industries these days demand frictionless low-bearing motors to avoid noise on sites. The 1 horsepower three phase motors are low noise bearing, confirming the less vibratory industrial operation. Moreover, these features make the 1 hp 3 phase electric motors eco-friendly by reducing noise pollution.

High starting torque:

The 1hp three-phase motor provides high initial rotatory motion to the motor without any external power device. However, a capacitor can be used to increase the power efficacy of the motor. Due to this incredible feature, 1 hp 3 phase electric motors are widely used in numerous technology fields.

Construction of 1 hp 3 Phase Electric Motor

Figure 2: Construction of 1 HP 3 Phase Electric Motor


The moveable rotating part of the 1 hp 3 phase motor is called a rotor. The motor completes its revolutions in the direction of the stator due to electromagnetic induction. Therefore, it produces an induced current in the direction of magnetic fields. The shaft is enclosed in the rotor bearing. The shaft rotates and carries current.


The stator of the motor controls the rotor movement and influences it to move in the direction of provided magnetic fields. The stator of the 1 horsepower 3 phase motor is made up of 100% raw material and stainless/fabricated steel. The high-grade material used in the stator provides support and stability to the other parts of the stator (e.g., winding and stator core). 

Stator Winding and Poles of 1 hp 3 Phase Motor

Figure 3: Stator Winding and Poles of 1 HP 3 Phase Motor


The winding of a 1 hp 3 phase electric motor is made of 100% copper coil to ensure high resistivity and long life. When we provide a three-phase current supply to the motor, its winding establishes a rotating magnetic field in the stator. The cooper coil and high-grade wire used in the windings make them heat and water-resistant.
