Specification requirements and ambient temperature of Permanent magnet DC speed reducing motor

Jul 07, 2018

Permanent magnet DC speed reducing motors should use ferrite permanent magnet DC motors with high efficiency, low price and low temperature rise. When operating, they should only be considered when the performance requirements are strict, the volume is small, and the ambient temperature is high. AlNiCo permanent magnet DC motor or rare earth permanent magnet DC motor.


The maximum power of the output of the permanent magnet DC gear motor is limited. To a certain extent, if the power selection of the motor is too small, the load will exceed the rated output power of the motor, and the motor overload will occur directly. When the motor is overloaded, the motor will appear. 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.


The permanent magnet DC gear motor will be limited to a certain extent due to the actual production specifications. When selecting the product specifications, it can be considered. When the power supply voltage is adjustable, the torque, speed and corresponding rating of the product can be selected according to actual needs. Close to the specification, the required speed can be obtained by changing the voltage. If the power supply voltage is fixed, if there is no suitable specification for the product, you can select the appropriate specification according to the torque, and the voltage and speed of the product can be appropriate. Adjustment.
