Wire color correspondence description:
1. The red wire power is positive pole, the black wire power is negative pole, the white wire is speed regulating wire, the yellow wire signal is feedback wire (speed measurement), and the green wire is commutation wire (floating inversion, connected to the power supply negative pole).
2. Speed regulation port: PWM and 0-5V speed regulation, speed range 13% -100% PWM
Frequency 10KHZ-30KHZ, Amplitude: 5V Duty cycle 0-10% Motor does not rotate, 11% -100%
Speed adjustment interval; 0-5V voltage speed adjustment, 0-0.5V motor does not rotate, 0.6V-5V speed adjustment interval
3. The yellow wire speed feedback is connected to the oscilloscope probe or host computer. 1 pulse / rev.
4. Run at full speed. The red and white wires are connected to the positive power supply and the black wire is connected to the negative power supply.
