JUYI Wide Voltage 7-48V DC Sensor less Motor Controller 10A with Dual Control

Application Instructions
1. Confirm the voltage and power parameters of the motor, which should not exceed the range specified for
this driver board.
2. This driver board is suitable for driving three - phase DC brushless motors. However, not all three - phase DC
brushless motors can be used directly. If the driving effect is poor (such as startup jitter, reverse rotation,
excessive current at high speed of the motor, unstable rotation speed, reduced efficiency, and failure to start
after loading), customers can adjust the parameters such as resistors and capacitors of the driver board according
to the actual situation to achieve the best driving effect .
3. The JYQD_V6.3B driver board is a bare board. For motors with a power below 100W, forced heat dissipation is not
required, but normal ventilation must be ensured.
4. The 5V output port on the driver board is prohibited from connecting external electrical equipment. It is only suitable
for external potentiometers and switches on this board for speed adjustment and commutation.
5. The "Signal" on the JYQD_V6.3B driver board is the pulse output signal of the motor speed, and the output current
is less than 5mA.
