Find the rated and maximum torques, Electrical Engineering

Assignment Help:

A 4000-V, 5000-hp, 60-Hz, 12-pole synchronous motor, with a synchronous reactance of 4  per phase (based on cylindrical-rotor theory), is excited to produce unity power factor at rated load.

Neglect all losses.

(a) Find the rated and maximum torques.

(b) What is the armature current corresponding to the maximum torque?
