Variable Torque: A multi-speed motor used on loads whose torque requirements vary with speed as in some centrifugal pumps and blowers. The HP varies as the square of the speed.

Pull-In Torque: The maximum constant torque which a synchronous motor will accelerate into synchronism at rated voltage and frequency.

Locked Rotor Torque: The minimum torque that a motor will develop at rest for all angular positions of the rotor (with rated voltage applied at rated frequency).

Constant Torque: Refers to loads whose H.P. requirements change linearly with changing speeds. Horsepower varies with the speed, i.e.- 2/1 HP at 1800/900 RPM. (Seen on some 2-speed motors). Possible applicat . . . View Full Definition

Breakdown Torque: The maximum torque a motor will develop at rated voltage without a relatively abrupt drop or loss in speed.
