The characteristics and application of dc motor

The characteristics and application of dc motor:

    Main advantages: Compared with AC three-phase asynchronous motor, the characteristics and application of dc motor has good starting characteristics and speed regulation characteristics, the characteristics and application of dc motor ,which is convenient for speed regulation. Therefore, for the production machinery with high starting and speed regulation performance, DC motor drive is often used.The characteristics and application of dc motor main disadvantage: you need to configure the DC power supply, the price is relatively expensive.

The characteristics and application of dc motor:

   1) When the production machine needs to maintain a constant speed under different load conditions and the speed can be adjusted, a DC motor can be used. For example, a shunt DC motor can be used to drive a grinding machine, a planer, and the like.

The characteristics and application of dc motor:

    2) When the starting condition of the production machinery is heavy, and when the resistance torque increases and the allowable speed decreases, the characteristics and application of dc motor ,the series-excited DC motor can be selected. For example, a series-excited DC motor can drive electric locomotives, cranes, cranes, elevators, and the like.

The characteristics and application of dc motor:

    3) When the production machinery needs to have a large starting torque, the characteristics and application of dc motor  and the acceleration is faster when starting; when the load increases, the speed decreases more, the characteristics and application of dc motor and it is not afraid of no-load, and a compound-excited DC motor can be selected. For example, accumulative DC motors can drive rolling mills, printing presses, paper machines, elevators, cranes, etc.
