Torque required for constant HP is
Torque = 5250 x HP = 5250 x 3 = 1.75 ft-lbs
RPM
This number is greater than the 1.08 ft-lbs calculated as the motor's torque ability at 300 Hz.
Therefore, the motor cannot provide constant HP at up to 300 Hz. In fact, the maximum HP the motor can
develop at 300 Hz is:
HP = Torque x RPM = 1.08 x 9000 = 1.85 HP
5250
