Permanent magnet DC geared motor specifications and power

Mar 17, 2018

Permanent-magnet DC geared motors should be effective in selecting the ferrite permanent magnet DC motor with high efficiency, low cost, and low temperature rise. Permanent magnet DC geared motors only consider the use of aluminum nickel-cobalt permanent magnet DC motors or rare earth permanent magnet DC motors when the performance requirements are strict, small and the ambient temperature is high.

Permanent magnet DC geared motor reasonable choice of motor power

The maximum output power of the permanent magnet DC speed reduction motor is limited to a certain extent. If the power of the motor is selected too small, the load exceeds the rated output power of the motor, so that the motor will be overloaded, and the overload will occur. There are phenomena such as motor heating, vibration, speed drop, abnormal sound, etc. In severe overload, the motor will be burned. If the power is too large, it will cause economic waste. Therefore, it is very important to choose the power of the motor reasonably.

Selection of specifications for permanent magnet DC geared motors

In the actual production process, permanent magnet DC geared motors will have more products because of the small size of their products. In the process of selection, products will be used to increase their difficulties. When selecting product specifications, consider: When the power supply voltage is adjustable, According to the actual needs, select the torque, speed and product corresponding to the corresponding rating of the specification, by changing the voltage to obtain the required speed; in the case of a fixed supply voltage, if there is no suitable specifications of the product available, you can press the torque Select the appropriate specifications, and the voltage and speed of the product can be adjusted appropriately.

Under normal circumstances, if there is no description of its products, its equipment will never be allowed to operate under the rated voltage, but it will cause the demagnetization of the permanent magnets. If it is necessary to operate this way, it is necessary to add a current limiting resistor. To limit the current is too large.
