Variable Reluctance Stepper Motor: Variable reluctance stepper motor can be of single-stack or multi-stack type. Single Stack Variable Reluctance Motor: A variable reluctance stepper motor has salient pole (or tooth) stator and rotor. While rotor has no windings, stator has concentrated coils placed … (Read More)

Advantage and Disadvantage of Stepper Motors: Advantage and Disadvantage of Stepper Motors are as follows; Advantages They are compatible with digital systems and do not require digital to analog conversion at the input, as do conventional servos, when used with digital systems or … (Read More)

Drive Circuits for Stepper Motor: A Drive Circuits for Stepper Motor is usually driven from a low voltage dc source. When a phase is to be energised, the dc source is connected to the phase by a semiconductor switch S (Fig. … (Read More)

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 performance requirements. A stepper motor is designed to make it suitable … (Read More)
