How To Choose Dc Brushless Motor?

The miniature brushless DC motor is a kind of miniature, high efficiency, low noise and low power consumption motor. It has the advantages of quick start, rapid response and high precision, and can be widely used in various electronic equipment. Choose your own mini motor brushless, you can improve the performance and life of the product, here will introduce some of the main points of choosing brushless DC motor.

1. Specification selection
The speed and torque of the tiny brushless motor are important factors to consider when selecting. The speed is usually between 5000rpm and 3000rpm, and the torque is related to the size of the motor and the gear ratio. Select different speeds and torques according to different application scenarios. The desired speed is obtained by changing the voltage; In the case of fixed power supply voltage, if there is no suitable brushless DC motor available, the appropriate specification can be selected according to the torque, and the voltage and speed of the product can be adjusted appropriately.
2. Power selection
The power output of the motor is limited, and the power is selected according to the load that the motor is to drive. If the load is relatively large, it needs to consume more power to drive the load operation. If the load is relatively small, the power can also be selected to be smaller. If the power selection of the brushless motor is too small, the load exceeds the rated output power will occur motor overload, overload will appear motor heating, vibration, speed reduction, abnormal sound and other phenomena, serious overload, will burn the motor. If the power is too large, it will cause economic waste. Therefore, it is very important to choose the power of the motor reasonably.

3. Type selection
It is advisable to choose the 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 can the aluminum nickel-cobalt permanent magnet DC motor or rare earth permanent magnet DC motor be considered. The use of bldc motor environment also needs to be considered. For example, if the motor needs to be used for a long time in a high temperature environment, you need to choose a model that can adapt to the high temperature environment. If the brushless motor needs to be used in a humid environment, it is necessary to choose a moisture-proof and shock-proof model.
