Note: This driver is a DC three-phase brushless control board. The motor needs Hall to work properly. Only applicable to electrical angles of 120 degrees.

If you are not clear about the definition of the motor phase line and the Hall line, and it cannot work properly after being connected, you can blindly connect according to the following method and then slowly change the Hall line sequence. First, connect the three phase lines of the motor to the phase line interface of the driver board at will. There are five Hall lines on the motor. Three Hall signal lines are connected to the three Hall signal ports on the driver board at will. The other two Hall power supply lines must be connected correctly (the motherboard will provide 5V power supply. One of the Hall lead wires we send is red 5V and the other is black ground wire. You must find a way to connect it to the motor Hall power supply line. Remember!!!) After checking that everything is connected correctly, power on for low voltage (7-12V) and low current (1-3A) power-on debugging (if conditions permit, use constant DC power supply or low power power supply plus current limiting resistor, etc.), turn on the potentiometer on the board to adjust the speed throttle to about 20%. If the motor does not rotate or there are other abnormal phenomena, immediately turn off the power, and then change the order of the three phase lines of the motor (because the phase line interface on our driver board is a terminal, it is more convenient to connect and remove the wires, so I use the motor phase line to change the line sequence. If the motor phase line is fixed, the principle of changing the three Hall signal line sequence is the same. It depends on personal preference). Until it can rotate smoothly after power is turned on, it means that the wiring is correct. There are 6 different combinations of line sequence change. I will list them below: If the order of the currently connected phase lines is defined as ABC, it can be changed to ACB BAC BCA CAB CBA. Each time these combinations are changed, the machine is tested once. Only 1 of these 6 combinations is correct.

When the wiring is incorrect and the operation is abnormal, do not test the machine with high current and high voltage, otherwise there is a risk of damaging the driver board. After the three motor phase lines are swapped, if the line sequence is correct, the motor will run as smooth as silk after power on, start smoothly at low speed, and have high torque; if the three motor phase lines are not connected in the right order, generally there are 1. After power on, the motor cannot start normally and has no response, or it only shakes when starting and cannot rotate normally. 2. There is a slight shake, it is difficult to start, it cannot turn, and it makes a slight sound. Sometimes it needs to be manually turned to turn. 3. The motor can turn in one direction, but not in the other direction, and there is some slight sound. 4. The motor starts with a large shake and is weak, there is a sound, and the current is obviously too large. The power tube is obviously heated and serious
