Dc Motor Speed Formula

The direct current motor is used to convert the electrical energy into mechanical energy. The torque is the turning force with the unit Nm in the SI units. The torque developed in the dc motor changes when the device accelerates from zero to its maximum speed. The current and torque of the motor are increased when more load is induced in the motor. The value of the rotational mechanical power is divided by the value of the angular velocity is the dc motor speed formula.


Torque = Prot / ω


Prot = Rotational Mechanical Power
ω = Angular Velocity
