DC brushless motor how to choose the model parameters

With the continuous development of technology, the motor industry products are becoming more and more advanced, such as brushless DC motor, compared to the original AC motor, the advantages in all aspects are more obvious, then how to choose the DC brushless motor model? Many friends may not be very clear, the following Vacuz simple to introduce you

Generally speaking, according to the load, structure, to choose the suitable power, voltage, speed, torque and machine size, and then according to the parameters of DC brushless motor to match the brushless driver.

1. Rated voltage, when choosing the rated voltage, select the brushless drive voltage parameters according to the demand, it is noted that the voltage should not exceed the range specified by the brushless drive when used during no-load and full-load.

2. Brushless driver peak current. A common method is to know the rated input current of the DC brushless motor, then the peak current is greater than or equal to two times the rated current.

3. According to the working environment, such as temperature, humidity, etc., the temperature of DC brushless motor can not be lower than -20 degrees, or higher than 60 degrees, of course, you can also do waterproof treatment.

4. Power insulation effect, brushless drive can operate normally, and Hall ground and winding, shell insulation resistance, should be greater than 100 megohm 500VDC.

5. DC brushless motor outside diameter, and DC brushless motor height, the diameter of the output shaft, whether it needs to be equipped with a reducer and other related parameters.

How to choose the DC brushless motor model is also based on the above parameters, and if there are no suitable parameters, it needs to be customized.
