Switched reluctance motors are mainly used in traction, industrial and automotive pumps and home appliances (vacuum cleaners and certain washing machines). Their structure is similar to that of stepper motors, but switched reluctance motors have fewer magnetic poles. Despite their simple structure, external electronic commutation is needed.
Asymmetrical Half-Bridge PWM Drive
The asymmetrical half-bridge PWM drive leverages the motor’s best features. An independent current loop is implemented for each motor phase so that some phase current overlap is possible to attain higher speeds. For the drive, 2 x n power switches arView application
