How do you calculate motor torque?

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.

How do you describe torque?

Torque is a twisting force that speaks to the engine’s rotational force and measures how much of that twisting force is available when an engine exerts itself. … This applies torque, or a twisting force, to the bolt. While horsepower is simply measured in horsepower, torque is typically measured in pounds feet (lb.

What is the torque constant of a motor?

The Torque Constant defines the torque-current relationship of a motor and is in Nm/amp. The motor and torque constants are related by the formula Km = Kt(trap)/sqrt(R), where R is the phase-to-phase resistance of the winding.
