The speed regulation of a motor falls from 1100 rpm at no load to 1050 rpm at rated load. The speed regulation of the motor is:

An increase in the torque angle a results in: O A. No change in the induced torque O B. Decreasing the induced torque O C. Decreasing the load on the synchronous motor D. None of the other choices are correct O E. Increasing the induced totque

divided by rpm. Torque equals horsepower 5252 a. b. horsepower x 5252 voltage x horsepower C. d.

A three-phase, four-pole, 440-V (line-to-line), 60-Hz induction motor is supplied from a constant Volts/Hertz adjustable speed drive controller. The motor has a magnetizing inductance of 80 mH per phase and an effective rotor resistance referred to the stator side of 0.4 per phase. Leakage reactances and stator resistance may be neglected.
