Question: Replace the 28-tooth rotor of Problem 8.7 with a rotor with 26 teeth. a. Phase 1 is excited, and the rotor is allowed to come

Replace the 28-tooth rotor of Problem 8.7 with a rotor with 26 teeth.

a. Phase 1 is excited, and the rotor is allowed to come to rest. If the excitation on phase 1 is removed and excitation is applied to phase 2, calculate the resultant direction and magnitude (in degrees) of rotor rotation.

b. The stator phases are to be excited as a regular sequence of pulses. Calculate the phase order and the time between pulses required to produce a steady-state rotor rotation of 80r/min in the counterclockwise direction.
