The permanent magnet DC motor for earthing switch is suitable for use with ferrite permanent magnet DC motor with high efficiency, low price and low temperature rise. Only when the performance requirements are strict, the volume is small, and the ambient temperature is high, the AlNiCo permanent magnet DC motor or the rare earth permanent magnet DC motor is considered.
Reasonable selection of motor power by permanent magnet DC motor for earthing switch
1. The maximum power output of the motor is limited. If the power selection of the motor is too small, the motor overload will occur if the load exceeds the rated output power of the motor. When the overload occurs, the motor will generate heat, vibration, speed drop, abnormal sound, etc. When the battery is severely overloaded, the motor will be burnt. If the power is too large, it will cause economic waste. Therefore, it is important to choose the power of the motor reasonably.
Specification selection of permanent magnet DC motor for earthing switch
When selecting the product specifications, consider: in the case where the power supply voltage is adjustable, the torque, the speed and the corresponding rating of the product can be selected according to actual needs, and the required speed can be obtained by changing the voltage; in the case where the power supply voltage is fixed, If there is no product with the appropriate specifications to choose from, you can select the appropriate specifications according to the torque, and the voltage and speed of the product can be adjusted appropriately.
