Brushless motors (BLDC) are widely used in industries such as artificial intelligence, automobiles, medical equipment, and industrial automation due to their long life, low noise, and high torque. Due to their different specifications and types, it is very important to choose a brushless motor to meet the performance requirements of the product. The following Chaoya Motor introduces 3 references for choosing brushless motors:
1. Type selection
Priority will be given 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 should only be considered when the performance requirements are strict, the size is small, and the ambient temperature is high.
2. Specification selection
When the power supply voltage is adjustable, you can select a DC motor specification with a torque and speed close to the corresponding rating of the product 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 brushless Motors are available to choose from, suitable specifications can be selected based on torque, and the voltage and speed of the product can be appropriately adjusted.
3. Power selection
The maximum power output of the motor is limited. If the power selection of the brushless motor (BLDC) is too small, motor overload will occur when the load exceeds the rated output power. When the motor is overloaded, phenomena such as heat, vibration, deceleration, and abnormal noise will occur. When the motor is severely overloaded, it will burn out. If the power is too high, it will cause economic waste. Therefore, it is very important to choose the power of the motor reasonably.
Different specifications of brushless DC motors (BLDC) have different characteristics and advantages. Therefore, it is necessary to master the principles and methods of selection to achieve optimal performance, high efficiency, energy conservation and environmental protection. If you can't find a brushless motor that suits your product, you can also customize it according to the performance of your product.
