Question

A single-stack, eight-phase (stator), multipole, stepper motor has six rotor teeth. The phases are excited one at a time.

(a) Determine the step size.

(b) Determine the steps per revolution.

(c) Determine the rpm, if the excitation frequency is 120 Hz.

David · Accepted Answer

Solution:
    Consider the following data for a multipole (two-pole) single-stack stepper motor 
    The number of phases (at stator) is, 8N

    The number of rotor teeth is, 6x  
    The excitation frequency is, 120f Hz

(a) The step size (at rotor) for a stepper motor is,
