How to choose a brushless motor?

The electric vacuum cleaner motor is more and more popular with customers because of its long life, low noise, high torque, adjustable speed, etc. It is widely used in smart homes, artificial intelligence robots, automobiles, vacuum cleaner motors, medical equipment, industrial automation, and other industry. Brushless motors come in different sizes and sizes. How to choose a brushless motor to meet the performance requirements of your products and reduce manufacturing costs. Here are a few ways to choose a brushless motor.

1. Size specification selection

In the case of adjustable power supply voltage, the specification of brushless DC motor with torque and speed close to the corresponding rated value of the product can be selected according to actual needs, and the required speed can be obtained by changing the voltage; when the power supply voltage is fixed, if there is no suitable When brushless motors can be selected as DC motors, appropriate specifications can be selected according to the torque, and the voltage and speed of the product can be adjusted appropriately.

2. Power size selection

The maximum power output of the motor is limited. If the power selection of the brushless motor is too small and the load exceeds the rated output power, the motor will be overloaded. When overloaded, the motor will heat up, vibrate, slow down, and make abnormal sounds. Severe overload will burn the motor. Excessive power will cause economic waste. Therefore, it is very important to choose the power of the motor reasonably.

3. Type selection

DC vacuum motors manufacturers should give preference to ferrite permanent magnet DC motors with high efficiency, low price and low temperature rise. Alnico permanent magnet DC motors or rare earth permanent magnet DC motors are only considered when the performance requirements are strict, the size is small, and the ambient temperature is high.
