Stepper Motor and Switched Reluctance Motor Drives

Switched Reluctance Motor

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 for open loop position and speed control in low power applications, where efficiency is …

Advantage and Disadvantage of Stepper Motors

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 a computer. While simple open-loop control is good enough for the control …

Variable Reluctance Stepper Motor

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 over the stator poles (teeth). Stator winding phase number depends on the …
