Brushless dc motor with long life, low noise, high torque characteristics are widely used in intelligent AI, automobiles, medical equipment, industrial automation and other industries, because it has different specifications and types, so how to select the brushless dc motor, in order to meet the product performance requirements, it is very important. Below the motor to introduce a few select the principle of brushless motor. Choose the brushless dc motor need to refer to the following factors: 1, choice of specifications in the power supply voltage is adjustable, can choose according to the actual need, rotational speed and torque products corresponding rating is close to the brushless dc motor specifications, by changing the voltage to get the required speed; In the power supply voltage is fixed, if there is no available for selection of the appropriate brushless dc motor, can according to the torque first selecting the appropriate specifications, the product of voltage and speed can make appropriate adjustments. 2, power selection, motor output maximum power is limited, if the brushless motor power to choose is too small, the load exceeds the rated output power of motor overload occurs, motor overload occurs fever, vibration, speed down, abnormal phenomenon such as voice, serious overload, will be burning motor. While power is too big, can cause economic waste. So the selection of motor power is very important. 3, type, choose appropriate priority to choose high efficiency, cheap price, low temperature brushless dc motor. Only when strict in performance, small volume and high ambient temperature when consider to choose aluminum nickel and cobalt permanent magnet dc motor or rare earth permanent magnet dc motor. Various specifications of the brushless dc motor has different characteristics and use of the advantages, so be sure to master the selection principles and methods, so as to make our products to achieve the best performance, and efficient energy conservation and environmental protection. If you find your products of brushless motor, can also according to your customized product performance.
