Brushless DC motor applications are getting hotter and hotter, and the field is becoming more and more extensive, mainly using electronic commutation, instead of traditional contact commutator and brush, the advantage is higher reliability, no commutation spark, low mechanical noise, so what aspects to pay attention to when buying brushless DC motor? How to avoid the pit!

Brushless DC motor

1. Pay attention to the voltage of the brushless DC motor.

The voltage is provided by the electronic switching circuit controlled by the position sensor output. When choosing brushless DC motor products, first select the correct voltage, and select the voltage parameters of the driver by choosing the rated voltage according to the customer’s needs. The voltage used during no-load and full-load should not exceed the range specified by the driver.

2. Pay attention to the current of the brushless DC motor.

We choose the peak current of the drive, the rated input current of the motor is known Ir (A, then the peak current Ip (A) = 2xIr, if the rated output power (or output power) of the motor is known Pr (W) and drive voltage Vr (V), then the peak current Ip (A) ≧ 4xPr/Vr.

3. Pay attention to the operating temperature of the brushless DC motor.

We can also set the motor according to the parameters, but we need to set its appropriate parameters according to different motors. Of course, we also need to consider the application range of temperature, in general, the wider the temperature, the higher the price.

4. Pay attention to the resistance of the brushless DC motor.

According to the power supply insulation requirements to ensure the normal operation of the drive.
