Toshiba G3 Workbook page 66

Check with motor manufacturer for top speed capability of your motor. The balance of the
motor's rotor and bearing life are of concern during overspeed operation. Make sure the machine
pulleys or gearbox are sized for 3600 RPM.
Both of the following motors have the same torque rating of 150 ft-lbs at 60 Hz:
50HP, 230V, 326T frame, 1800 RPM, 122 amps (will be run up to 480V 120 Hz 3600
RPM)
100HP, 460V, 405TS frame, 3600 RPM, 120 amps (will be run up to 480V 60 Hz 3600
RPM)
A 100 HP G3 would be used with either motor. Notice that the 50 HP motor is in a smaller frame.
