3 pahses DC 7-48V JUYI Brushless motor driver board 10A sensorless
motor speed controller with PWM control
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_V6.3B drive board is bare board, drive power below 100W
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 Signal on the JYQD_V6.3B driver board is the motor speed
pulse output signal, and the output current is less than 5mA.

Port Description
1.Control Port
GND — Used for Driver board internal control
VR — Speed control port. Analog voltage speed regulation 0V-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 or no connect in one
direction, connect GND to the other direction.
Signal — 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
P+/VCC — DC +
P-/GND — 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. It will cause signal interference If the wire is
too long.
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.
