Application notes:

 

1. Confirm that the voltage and power parameters of the motor not exceed the range of the driver board 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 (see the attachment for how to do the adjustment)

 

3.JYQD_V8.20B drive board is bare board, drive power below 36W motor does not need to force heat dissipation, need to ensure normal ventilation.

 

4.The 5V output port on the driver board is prohibited from connecting to external electrical equipment. It is only suitable for connecting external potentiometers and switches to this board for speed regulation and reversal.

 

5. The M port on the JYQD_V8.20B drive board is the output of the motor speed pulse signal, and the output current is less than 5mA.

Port Description

 

1.Control Port (Left)

 

GND — Used for Driver board internal control

 

VR — Speed control port. Analog voltage speed regulation 0.1V-5V speed regulation, linear speed regulation from low to high. PWM speed                       regulation needs to be grounded with the driver board.

 

Z/F — Rotating direction control ports.Connect 5V high level or no connect in one direction, connect 0V low level or GND to the other direction.

 

FG — Motor speed pulse signal output port, 5V pulse signal

 

5V — Driver board internal output voltage, external potentiometer or switch for speed adjustment and reversing operation.

 

2. Power Port(Right)

 

P+ — DC +

 

P- — DC -

 

MC — Motor Phase C

 

MB — Motor Phase B

 

MA — Motor Phase A

 

3. Please pay attention to the motor phase wire and Hall wire not to be too long, because the driver board relies on back electromotive force detection, it will cause signal interference If the wire is too long.

 

4. The port distance is 2.54mm for both Power port and Control Port.

 

5. When adding heat sink or placing the driver board, please pay attention to the insulation for the driver board.
