Shunt motor characteristics
WebIn the case of DC series motors, the change in the supply current causes a change in the magnetic field, which in turn causes variation in the speed of the motor. Therefore, the series DC motors are variable speed DC motors.. One of the most important characteristics of a DC series motor is that it produces very high torque at low speeds and vice-versa. WebOct 15, 2024 · Torque Speed Characteristics of Shunt Motor. Basically, in a shunt motor, the field winding is connected in parallel to the armature winding. Whenever a current is supplied by means of a DC source, flux is …
