WebAug 5, 2024 · However, in a separately excited DC motor, a separate supply is used to excitation both the armature coil and the field coil. These motors, like other DC motors, feature both a stator and a rotor. The field windings make up the stator, which is the static element of the motor. The rotor, on the other hand, is the moving armature, which is … WebNov 17, 2024 · Let us consider a pulley or a wheel with a radius of r metre. When a circumferential force of F newton acts upon the pulley, it will cause the pulley to rotate at N rpm. Torque is given by the formula, T = Force * radius. Work done by the pulley = force * distance moved. Work done by the pulley = F * 2πr joule.
WebOct 12, 2024 · The torque equation of a DC motor has been derived as, From the above equations, it can be observed that, increase in flux would increase the torque but decreases the speed of the motor. But it is not possible, because torque is the rotation force, which tends to rotate the motor. Hence increase in torque always increase the …
