2. How Does A 3 Phase 1HP Electric Motor Function?

A 3 phase 1HP electric motor is operated by using three-phase AC currents. Here, a  coil is found inside this motor that generates a magnetic field. The oscillating AC and magnetic field change their positions, enabling the stator to produce a revolving magnetic field.

This variable magnetic field causes current induction to the rotor coil. It results in creating magnetic force in the rotor in the opposite direction. Net torque is generated when the rotor and stator field intend to align in terms of polarity.

3 phase 1 HP electric motor windings produce a rotating magnetic field when linked with the alternating current. Then, you can change the number of poles to optimize the motor speed as per your requirements.
