Second, we choose the peak current of the driver. The method of selecting the peak current is the rated input current Ir(A) of the motor, and the peak current Ip(A)>=2xIr. Otherwise, the output current during the use of the driver does not have a certain engineering. Balance, if the rated output power (or maximum output power) Pr (W) and the drive voltage Vr (V) of the motor are known, the peak current Ip(A) ≧ 4xPr/Vr. Third, we can also set the motor according to the parameters, but we need to set the parameters according to different motors. Of course, we need to consider the temperature range. The wider the temperature, the higher the price. The drive brake of the DC brushless motor adopts the short-circuit brake of the motor end, and the brake force of the motor is running. When the motor is not running, there is no brake force. The higher the speed, the greater the braking force. Since the brake current does not pass through the current sensing resistor, the brake current cannot be controlled. Therefore, the braking speed should not exceed the safety brake speed, otherwise the power tube may be burned out. Please use this function carefully. Fourth, there is also a key point of power insulation requirements. In order to ensure the normal operation of the driver, the insulation resistance between the Hall line ground wire and the motor winding wire, the Hall ground wire winding wire and the casing of the motor is greater than 100 megohm 500VDC. Can withstand 600VAC/50Hz/1mA/1 second withstand voltage without breakdown.

DC brushless motor selection considerations
First, the choice of DC brushless motor products should first select the correct voltage, select the rated voltage according to the customer's needs to select the driver voltage parameters, pay attention to the voltage used in the no-load and full load process should not exceed the range specified by the driver.
