Determine the operating speed and power of a PM DC brush motor with the following operating characteristics: Starting torque = 200 oz-in. no-load speed = 4000 rpm, load = 80 oz-in.

A geared PM DC brush motor has a gear ratio of 50:1. The input speed is 4000 rpm at an input power of one-half horsepower. Determine the output torque of this motor, assuming a 5% power loss in the gear drive.
