How To Choose Brushless Motors?

　　Brushless motors are more and more popular with customers, because of their long life, low noise, high torque, adjustable speed, and other characteristics, they are widely used in smart homes, AI robots, automobiles, cleaner motors, medical equipment, industrial automation, and other industries. Brushless motors have different specifications and sizes. How to choose brushless motors can meet the performance requirements of your products and reduce manufacturing costs. Here are a few ways to choose brushless motors.

　　1. Size specification selection

　　In the case of adjustable power supply voltage, the specification of DC brushless motors 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; in the case of fixed power supply voltage, if there are no appropriate brushless motors When the DC motor is available for selection, the appropriate specification 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 brushless motors is too small, and the load exceeds the rated output power, the motor will be overloaded. When overloaded, the motor will heat up, vibrate, decrease in speed, and have abnormal sounds. Severe 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

　　The ferrite permanent magnet DC motor with high efficiency, low price, and low-temperature rise should be preferred. Alnico permanent magnet DC motors or rare earth permanent magnet DC motors are only considered when the performance requirements are strict, the volume is small, and the ambient temperature is high.
