Second, we select the peak current of the driver. The method of selecting the peak current is the rated input current Ir a of the motor, then the peak current Ip a & Gt; 2 * Ir, otherwise, the output current of the driver does not have a certain engineering surplus during the use of the driver. If the rated output power or the highest output power of the motor is known, then the peak value of the PCA2 * PR / Vr. Third, we can also set the motor according to the parameters, but we need to set it according to different motor parameters, of course, we also need to take into account the temperature range, the wider the price is higher. The lowest temperature can not be lower than-20 °C, and the highest temperature can be 60 °C. The DC brushless motor driver brake using motor end short-circuit brake, motor operation has brake force, not running there is no brake force, the higher the speed brake force. Because the brake current does not pass through the current sensing resistance, the brake current can not be controlled. Therefore, when the brake speed can not exceed the safety brake speed, otherwise it may burn out the power tube, this function please use with caution.
