Wiring diagram
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 BLDC motor driver
MOSFET and the heatsink or the installation plate.
Dimensional drawing
Application notes:
1. Confirm that the voltage and power parameters of the motor not
exceed the range of the BLDC motor driver board as specified. |
2. This BLDC motor 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-V8.3E sensorless BLDC motor 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 60W, it must add heatsink like the diagram as below. |
4. Please take note that JYQD-V8.3E BLDC motor 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 “M” terminal on the JYQD-V8.3E BLDC motor driver board is
the motor speed pulse output signal (push-pull output), and the
maximum output current is less than 5mA. |
