24V/36V/48V Brushless dc motor driver board, 15A current control panle for sensorless dc motor
18-50V 15A Original JUYI Tech JYQD-V8.5E bldc motor driver board for sensorless brushless DC motor,sensorless BLDC motor
(For Brushless Sensorless DC motor )
| Model number | JYQD-V8.5E |

| O.V / L.V protection | YES |
| Speed pulse signal output | YES |
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-V8.3E 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 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 driver board is the motor
speed pulse output signal (push-pull output), and the maximum
output current is less than 5mA.
Wiring diagram
| 5V | Driver board internal output voltage |
| M | Motor speed pulse signal output port, 5V pulse signal. |
| 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.
Dimensional drawing:
We can supply extra assy service: add connector wires , heatsink.
