An alternating current electric motor has a stator comprising an inductive winding in association with capacitance to ensure that the winding has the characteristics of a transmission line. The rotor of the motor may be of the induction, hysteresis or reluctance type. In one form, the winding of the stator is toroidal, such as gramme ring type, with shunt capacitors at fixed intervals along its length. In an alternative form, a linear motor has a solenoid type stator winding with shunt capacitors at fixed intervals. The invention enables speed to be closely defined without being essentially related to supply frequency. |
