Electromagnetics Torque and Power

Electromagnetic torque is the torque required to start the rotation of a motor, and it is generally equal to the load torque. The output electromagnetic torque (torque produced by the armature on the air gap) is the load torque at no load, and the load torque is equal to the electromagnetic torque. Due to electromagnetic force, electrical torque is a circular motion. Torque is the radial force from an axis of rotation. It is the vector cross product of the radius and force vectors.
