How to choose high-quality
brushless DC motors?
DC brushless motors are widely used in industries such as AI intelligence, automotive, medical equipment, and industrial automation due to their long lifespan, low noise, and high torque. Due to their different specifications and types, it is important to choose DC brushless motors to meet product performance requirements. Let me briefly introduce the brushless DC motor manufacturer below.
1. Specification selection
In situations where the power supply voltage is adjustable, a DC brushless motor specification 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 situations where the power supply voltage is fixed, if there is no suitable DC brushless motor available, the appropriate specifications can be selected based on the torque, and the voltage and speed of the product can be adjusted appropriately.
2. Power selection
The maximum power output of a motor is limited. If the power selection of a brushless motor is too small and the load exceeds the rated output power, motor overload will occur. During overload, phenomena such as motor heating, vibration, speed decrease, and abnormal sound will occur. In severe overload, the motor will be burned out. Excessive power can result in economic waste. Therefore, it is important to choose the power of the motor reasonably.
3. Type selection
It is advisable to prioritize the use of high-efficiency, inexpensive, and low temperature rise ferrite permanent magnet DC brushless motors. Aluminum nickel cobalt permanent magnet DC motor or rare earth permanent magnet DC motor should only be considered when strict performance requirements, small size, and high ambient temperature are required.
