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

Pull-Up Torque: The minimum torque developed by an AC motor during the period of acceleration from zero to the speed at which breakdown occurs. For motors which do not have a definite breakdown torque, the . . . View Full Definition

Starting Torque: The torque or twisting force delivered by a motor at the instant it is energized. Starting torque is often higher than rated running or full load torque.

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.

Torque: The twisting force at the motor shaft that drives the rollers on a treadmill and pulls the belt. The amount of torque is one of the variables used to calculate the amount of horsepower required.

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

Core Torque: Internal or core torque refers to the mass distribution within the core and the internal lever arms created by the core. Core torque is an assigned value of the ball's ability to combat roll . . . View Full Definition

Dual Torque: Dual speed motor whose torque varies with speed (as the speed changes the horsepower remains constant).
