Definitions:

Constant Torque

Describes motors or load types where torque demand does not change significantly with speed.

Driving Torque

The force that causes rotation in a mechanical system, typically generated by an engine or motor.

Operating Quadrants

The four potential modes of operation for a drive or motor, determined by the direction of torque and rotation or direction of current and voltage.

Torque

A measure of the force that can cause an object to rotate about an axis. It is a major consideration in machine design and operation.
