Repeat Problem 24 assuming the rotor shaft speed is 1150 rpm.

Problem 24

An induction machine is connected to a 60-Hz supply. The no-load rotor speed is 1200 rpm. The machine is driven mechanically to a speed of 1250 rpm. Under this condition, determine the frequency of the stator and rotor currents in the stationary, rotor, and synchronous reference frames. Determine the speed and direction of the stator and rotor MMF when viewed from an observer positioned on

(1) the stator and

(2) the rotor.
