This field rotates at synchronous speed.
Next, the rotor, the rotating part of the motor, is positioned inside the stator. The rotor does not have its own power source; instead, it interacts with the rotating magnetic field produced by the stator. The interaction induces a current in the rotor.
This induced current generates its own magnetic field in the rotor. The rotor’s magnetic field then interacts with the stator’s rotating field. This interaction creates torque, causing the rotor to turn.
The rotor continues to spin, following the rotating magnetic field of the stator. The speed of the rotor is slightly less than the synchronous speed to maintain the induction process. This difference in speed allows for the continuous generation of torque.
In summary, Tesla AC motors achieve motion through a process of induction, where a rotating magnetic field from the stator induces current in the rotor, resulting in a continuous rotational motion.
