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-V6.3E2 driver board is bare board without housing and
heatsink. If the power of the motor below 60W ,it does not need to
add heatsink, It only needs to ensure normal ventilation and well
insulation. If the power of the motor more than 100W, it must add
heatsink like the diagram as below.
4. 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.
5. The 5V output port on the driver board prohibits connect
external device. It is only applicable to the external
potentiometer and switch of the board for speed regulation and
reversal.
6. The “Signal” terminal on the JYQD-V6.3E2 driver board is the
motor speed pulse output signal (push-pull output), and the maximum
output current is less than 5mA.

5V -----Driver board internal output voltage
Signal ---- Motor speed pulse signal output port, 5V pulse signal.
1. Control port
| Z/F---- Rotating direction control ports. Connect “5V” high level or
no connect is Forward direction, connect 0 V low level or connect
to GND is reverse direction. |
| VR ----Speed control port. Analog voltage linear speed
regulation 0.1v -5V, The input resistance is 20K Ohm ,connect with
GND when input PWM speed regulation, PWM frequency:1-20KHZ; Duty
cycle 0-100% |
GND—Used for Drive board internal control |
2. Power port
| MA ----motor phase A |
| MB ---- motor phase B |
| MC---- motor phase C |
| GND----DC- |
| VCC----DC + |
3. Use shielded wires if the drivers board has more than 50 cm
distance from the motor, otherwise it may lead to abnormal driving,
affecting the normal use.
4.Control port distance: 2.54mm,Power port distance:3.96 mm
5. Pay attention to the insulation between the driver MOSFET and
the heatsink or the installation plate.
