A three-phase linear ac motor has an armature winding of

A three-phase linear ac motor has an armature winding of wavelength 25 cm. A three-phase balanced set of currents at a frequency of 100 Hz is applied to the armature.
a. Calculate the linear velocity of the armature mmf wave.
b. For the case of a synchronous rotor, calculate the linear velocity of the rotor.
c. For the case of an induction motor operating at a slip of 0.045, calculate the linear velocity of the rotor.
