15A 24 Volt Sensorless BLDC Driver Board Speed Control 3
Application guidelines

1: Confirm that the voltage and power paraparameters of the motor not exceed the range as specified.



2:This driver board is used for 3-phase brushless sensorless motor, but not suit for all 3-phase brushless sensorless motors directly. If the driving effect is not good (such as starting jitter, reversing, the motor noload working current is too large, the speed is not stable, the efficiency is low, and can’t start-up with load.) Customers can adjust the resistance and capacitance of the driver board according to the actual situation to achieve the best driving effect (contact us for guidance)




3:JYQD-V6.3E2 is driver board without housing and heatsink, it can drive the BLDC motor below 100W without any heatsink,but needs normal ventilation.

4:The "5V" pin on the driver board is forbidden to connect with external power equipment.it is only suit for external potentiometer or switch for speed adjustment,reversing and singnal swtiching operation.




5: Please take note that JYQD-V6.3E2 driver board has no anti-reverse connection protection, it will permanently damage the driver board if reversed polarity connection.
