Three-phase permanent-magnet stepper motor (each pulse advance the motor by 60 electrical degree) required for one particular application must be capable of controlling the position of a shaft in steps of 7.5°, and it must be capable of running at speeds of up to 300 r/min. (a) How many poles must this motor have? Electrical angle =P\2 (mechanical angle) (b) At what rate must control pulses be received in the motor's control unit if it is to be driven at 300 r/min?
