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 pull-up torque is the minimum torque developed during the process of getting up to the rated speed. R - R (r bar) is the per unit armature circuit resistance using counter emf as a base. R = Hot IR voltage drop where Terminal volts - (Hot IR voltage drop)/ Hot IR voltage drop = (Rated lax Hot Arm. Cir. Resistance) + 2.0 (Brush drop) volts.

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

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.

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.
