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)
5V -----Driver board internal output voltage
M ---- 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, 1. 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
U/MA ----motor phase A
V/MB ---- motor phase B
W/MC---- motor phase C
AC----L
AC----N
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.This AC input driver board can be the built-in driver in application.
5. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
