Synchronous motors operate at a velocity that is synchronous with the frequency of the mains present. This implies that in the regular-state of the motor, the rotation of the shaft is synchronized with the frequency of the provide present. The period of rotation of the shaft is equal to the quantity of AC cycles. The stator of a synchronous motor has polyphase AC electromagnets. These electromagnets produce a magnetic subject that rotates in synchrony with the existing in the wire. The rotor geared up with long lasting magnets or electromagnets rotates synchronously with the stator magnetic subject to sort the second synchronous rotating magnetic area of the AC motor.
