The shaft of a three-phase synchronous generator is rotating at 1800 RPM synchronous speed. This generator is inducing a torque of 102.4 N.m under a certain load. If the copper losses are neglected, and the sum Praw + Pcore + P stray = 4826 Watt, Find the efficiency of the generator under those conditions.
