How does a three-phase motor work?

A three-phase motor is an AC motor that operates on a three-phase power supply, which means it has three electrical windings instead of one. Each of these windings is spaced 120 degrees apart from each other, and they are energized in a specific sequence by the three-phase power supply to create a rotating magnetic field.
The rotating magnetic field induces an electric current in the rotor (the rotating part of the motor) which causes it to turn. The rotor is made up of a series of conductive bars or coils, and as the rotating magnetic field passes over them, it induces a current which generates a magnetic field that interacts with the stator (the stationary part of the motor).
The interaction between the rotor and stator magnetic fields creates a torque that causes the rotor to rotate, and the motor to operate. Three-phase motors are commonly used in industrial and commercial applications due to their high efficiency, high power output, and reliability.
There are two main types of three-phase motors: induction motors and synchronous motors. Induction motors are the most common type and rely on the induction of a magnetic field in the rotor to create torque. Synchronous motors, on the other hand, require a separate power source to synchronize the rotor with the rotating magnetic field of the stator.
