Switched Reluctance Motor: The switched reluctance motor (SRM) has both salient pole stator and rotor, like variable stepper motor, but they are designed for different applications, and therefore, with different…
Self Controlled Synchronous Motor Drive Employing a Cycloconverter: Self Controlled Synchronous Motor Drive Employing a Cycloconverter as shown in Fig. 7.13. Firing pulses are generated either by comparison of the…
Operation of Synchronous Motor: Operation of Synchronous Motor - For any speed other than synchronous speed, the relative speed between air gap flux wave and the rotor is not zero.…
Synchronous Motors Types: Commonly used Synchronous Motors Types are: wound field, permanent magnet, synchronous reluctance and hysteresis motors. All these motors have a stator with a 3-phase winding, which is…
Eddy Current Drives: Eddy Current Drives consists of an eddy current clutch placed between an induction motor running at a fixed speed and the variable speed load. Speed is controlled…
Current Regulated Voltage Source Inverter: Current Regulated Voltage Source Inverter operates with current controlled PWM. In current controlled pulse-width modulation, machine phase current is made to follow a sinusoidal reference…
