A hybrid stepper motor has four stator poles and two 5-pole permanent magnet armatures, as shown in Figure Q3. amalure 2 A2 Figure Q3 Describe how the motor can be excited by a two-phase source to rotate in the counterclockwise direction.

A) Although the magnetic field for each phase of a 3-phase induction motor is merely switching back and forth between north and south poles, the resultant magnetic influence from all phases sets up a rotating magnetic field to cut the rotor conductors. a) true b) false B) In a two-pole stator winding of a 3-phase motor, how many revolutions does the rotating tr) magnetic field make in one cycle of the electrical current? a) one b) 60   c) 3600 d) none of the above
