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 12, 2024 · If the series field flux assists the shunt field flux, then it is a cumulatively compound motor. Such machines have the characteristics of both series motor and shunt motor. They are used in applications where the load is likely to be removed totally. Due to the shunt field windings, the speed will not become excessively high.

Web1. DC motor speed control does not normally use series, shunt compound or any other connection of the field to the same supply as the armature. The controller provides a separate regulated power supply for the field. The field current is maintained at a constant value unless field weakening is used to extend the operating speed above the normal ... WebIn the figure, the percentage speed regulation is hence. The figure 8.8 shows the three essential characteristics of a shunt motor, the torque, the speed, and the efficiency, each plotted against current. It will be noted that the shunt motor has a definite no-load speed. Therefore it does not run away when the load is removed, provided the ...
