Reminder:
Generally, there are 5 Hall cables on brushless motors, two of them are Hall power cables and three are Hall signal cables, especially the power supply cables. Don't make mistakes. Three Hall signal cables are connected to the driver board. The sequence must correspond to the sequence of the three phase wires on the drive board of the motor to work normally. If you don't know the definition of the Hall wire, you can debug it at low voltage and low current when the power is turned on for the first time, and change it slowly several times. Do not debug with high current and high voltage until normal operation. If the sequence of the Hall wires is not connected, test the machine with high voltage and large current, which may damage the MOS tube. If the three Hall signal wires are connected correctly The motor runs silky smoothly at low speed and starts smoothly. The torque is large; if the three Hall signal wires are not connected, there are the following characteristics: 1 The motor cannot start normally or it is difficult to start (sometimes it needs to manually turn the motor to start) 2 Motor Start-up jitter, weakness, bath sound, severe heating of the power tube
Interface Description:
1. MA MB MC phase line output is connected to the motor
2. 5V GND motherboard comes with 5V power supply (current does not exceed 30MA)
3. VCC GND motor main power supply (external DC power supply)
4. SC speed pulse signal output
5Forward and reverse forward and reverse control interface (also can be connected with a three-gear switch)
6.VR speed control signal input, (through the board with 5V GND connected to 10K potentiometer voltage divider speed control can also be connected with PLC0-5V analog input speed control)
7. PWM input, external amplitude is 5V PWM signal speed regulation (when external PWM needs to unplug the potentiometer on VR)
8.Ha Hb Hc +5V GND Hall signal power supply input, generally the motor with Hall has 5 corresponding wires
