| Application notes: |
1. Please confirm that the voltage and power parameters of the motor not exceed the range of the 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-V6.5E driver board is bare board without housing and heatsink. If the power of the motor below 100W ,its no need to add heatsink, It only needed 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-V6.5E 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-V6.5E driver board is the motor speed pulse output signal (push-pull output), and the maximum output current is less than 5mA. |
| 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 |
| Torque---For starting torque adjustment use, make sure remove the resistors for fixed-torque on the board before use this function (contact us if you want use this function before using) |
| MA | motor phase A |
| MB | motor phase B |
