Generally according to the actual situation (load, structure size, etc.) to select the appropriate power, voltage, speed, torque and body size, and then according to the specific parameters of the selected brushless DC motor, to match the brushless driver.

The parameters of Brushless DC motor are: DC power supply voltage, rated output power, rated load torque, rated working speed and the rotation direction of Brushless DC motor are: clockwise, counterclockwise or clockwise. The continuous working cycle of Brushless DC motor can operate according to a certain time. The environment of Brushless DC motor: Indoor, outdoor and sea In ocean, high pressure, high temperature, humid and corrosive gas, the flange structure has two forms: square and round, and the fuselage length.

(1) In the selection of Brushless DC motor model, the correct voltage should be selected first. According to the needs of customers, the rated voltage should be selected to select the voltage parameters of brushless driver. The voltage used should not exceed the specified range of brushless driver in the process of no-load and full load.

(2) When the rated input current of Brushless DC motor is known, the peak current is greater than or equal to twice the rated current.

(3) According to the working environment (such as temperature, humidity, etc.) to choose brushless DC motor, also can do waterproof treatment.

(4) Another important point is the requirement of power insulation. In order to ensure the normal operation of the brushless driver, the insulation resistance between the hall line ground wire of the brushless DC motor and the winding wire of the brushless DC motor, and between the hall ground wire winding wire and the housing is greater than 100 megohm 500VDC, which can withstand 600vac / 50 Hz / 1 mA / 1 second without breakdown.

(5) , the maximum outer diameter of the brushless DC motor, the height of the brushless DC motor, the diameter of the output shaft, whether it needs to be equipped with reducer and other relevant parameters.

To sum up, the selection of Brushless DC motor model is completed. If there is no suitable specification, it can be customized according to the actual demand.
