In the process of permanent magnet DC deceleration motor, the ferrite permanent magnet DC motor with high efficiency, low price and low temperature rise should be preferred. 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.
The maximum output of the motor output of the permanent magnet DC gear motor is limited. If the power selection of the motor is too small when the operation is performed, the motor overload will occur if the load exceeds the rated output power of the motor, and the motor will appear when the overload occurs. The phenomenon of heat, vibration, falling speed, abnormal sound, etc., will burn the motor when it is severely overloaded. If the power is too large, it will cause economic waste. Therefore, it is important to choose the power of the motor reasonably.
When the permanent magnet DC gear motor is used, it is often difficult to select the product due to the fact that the actual product specifications are not much. 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.
