Feature(may vary by option.)
●Three phase DC brushless with Hall motor controller, need motor with Hall to work properly. Brushless motor driver board, high power PLC. This driver is only for DC brushless with Hall motor with electric angle 120 degrees.
●New upgrade BLDC wide voltage 6-60V high power 350W, DC three-phase brushless with Hall controller, support PLC 0-5V touch volume control, support PWM control amplitude 2.5-5V.
●The main board power supply circuit without fuse, can be added(by yourself), the power supply positive and negative terminals will cause permanent damage to some of the chips on the board (not even for a few seconds when the high current)
●Motor output for sampling overcurrent protection, due to the module power supply current are very large. Do not artificially cause a short circuit in the normal operation of the module, a short circuit will damage the tube. Wiring test machine for small-current low-voltage test, successful then through the high-current high-voltage . Bare board module, pay attention to wire insulation when wiring, forbid strong voltage to touch the board.
●Do not connect the obvious and drive module voltage, current, power phase does not match or far from the motor to avoid inexplicable "nonsense" damage.

Description
350W Brushless Hall DC Motor Driver
Working voltage：6-60V（limit 60V leave a margin for use）
Operating current: rated 16A peak 20A
Power: rated 200-300W peak 350W (leave a margin to strengthen heat dissipation when using large power)
Overcurrent protection: Yes
Note:
1. Because the forward and reverse rotation is no delay hard commutation, and the brake will have a large impact, so you can not operate these two functions at high voltage full speed operation, forced operation may damage the power tube and chip, the need to speed control throttle down to 50% below before operation.
2. The maximum voltage (60V) and maximum power (350W) marked in this module are the limit parameters under specific conditions, so the actual application should leave a margin for use.
If you cant operate this controller, please consider buying it carefully.

Interface Description:
1.MA MB MC phase line output connected to the motor.
2. 5V GND main board with its own 5V power supply (can be external power supply, the current does not exceed 50MA).
3. VCC GND main power supply (external DC power supply).
4. SC speed pulse signal output (only leave out the interface, no tech+support).
5. DIR direction control, forward and reverse control interface (active low, can be external switch to ground).
6. STOP, stop control interface (active low, can be external switch to ground).
7. BRAKE brake control, brake control interface (active high, external switch to 5V).
8. Speed control speed signal input (integrated potentiometer on the board to regulate speed, can also be external 0-5V analog PWM dual signal input speed regulation).
9. Ha Hb Hc +5V GND Hall signal, power supply input interface, generally with Hall motors have the corresponding 5 lines.
External signal input special instructions:
1. From the motherboard P G 2 ports external PWM signal input (the board comes with a potentiometer to the minimum, while shorting the short interface on the board) amplitude 2.5-5V, frequency 50HZ-20KHZ.
2. External analog 0-5V input, from the motherboard 2 terminals sub port input (the board comes with a potentiometer to the minimum)
3. External potentiometer speed control, from the motherboard 3 terminal ports correspondingly connected (potentiometer on the board to the minimum)
4. Forward and reverse rotation and stop through a switch to ground (0 potential) low-level valid, but also external MCU to give a low-level signal. Brake through a switch to 5V, high level valid, the front row of terminals, are weak signals directly into the MCU main control, can not touch and contact with high voltage strong current.
Debugging instructions: Please read and understand before powering on the test machine, this is very important.
- 1. There are generally 5 Hall cables or interfaces on the brushless motor, 2 of which are Hall power lines and 3 are Hall signal lines, which should be distinguished, especially the Hall power lines (the Hall power lines are generally red and black lines). The three Hall signal lines are generally marked with a(Ha) b(Hb) c(Hc), and there are also three port characters such as ha Hb Hc on the driver board, which correspond to each other.
- 2. There are 3 relatively thick phase wires on the motor. There is also a three-phase line interface on the driver board. They are marked with MA(U) MB(V) MC(W) and similar characters, connect them accordingly, and confirm that they are correct. After the main power is turned on, the speed regulation of the potentiometer can be adjusted normally and smoothly. (If the interface is mapped correctly according to the tag, the power supply will not work properly).
- 3. If you do not know the definition of motor phase wire and Hall wire, you can connect the three-phase wire of the motor to the drive phase wire interface at will, and at the same time connect the three signal wires of the Hall to the Hall interface on the drive board. Connect the two hall power wires to each other (one red 5V and one black ground wire of the two hall power wires must be found and connected) and then the first power on, the low voltage is small. Current debugging (adjust the voltage of the constant current power supply to 7-12V current 1-3A if possible), if the motor does not rotate, change the order of the three-phase wires of the motor (connect to any two of the three-phase wires of the motor (wires on the driver board) Swap the wires, and exchange them once every power-on test), until it can rotate smoothly after power-on, which means the wiring is correct. There are 6 different line sequence replacement combinations, please see the picture.
- Please note: When using high voltage, high-speed commutation and braking are not allowed, otherwise the power tube may be damaged by impact.
