Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Torque and Speed Formula

Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label ' O '. We will call the force ' F '. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by ' r '.

The formula for figuring out torque is torque = horsepower of the engine x 5252, which is then divided by the rpms. It is not practical to control the torque of a stepper motor while it is operating. To measure the torque simply create a transversal arm attached to the motor using a known length.

At synchronous speed, no torque is produced by the motor, because no current is induced in the rotor windings. If the rotor rotates at a lower speed than the stator field, the motor runs in motoring mode. Otherwise, the motor operates in generator mode. The maximum torque, which can be obtained at the motor shaft, is called pullout torque.

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study.It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers.
