Brushless dc motor with low noise, high torque characteristics are widely used in smart cars, household appliances, 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. Brushless dc motor prices below small make up to introduce a few choose the principle of brushless dc motor.
1, specification choose
in the case of power supply voltage is adjustable, can choose according to the actual need, rotational speed and torque corresponding rating close to dc motor specifications of products, 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 dc brushless motor, can according to the torque first selecting the appropriate specifications, the product of voltage and speed can make appropriate adjustments.
2, power selection,
the motor output power is limited, if the power of brushless dc motor selection is too small, the load exceeds the rated output power of motor overload occurs, overload occurs for fever, vibration, speed drops, the phenomenon such as abnormal sound, 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, select the
appropriate priority to choose high efficiency, cheap price, low temperature of ferrite permanent magnet 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.
dongguan in different 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 dc motor, can also according to your customized product performance.
