The method of using the motor is very simple. If you just want it to run simply, then directly connect the red wire to the positive pole of the power supply, and the black wire to the negative pole of the power supply (the yellow wire is not connected), you can run at the highest speed, so adjust the voltage. The speed can also be adjusted.

If you need to use PWM speed regulation, the red wire is connected to the positive electrode, the black wire is connected to the negative electrode, the PWM signal wire is connected to the yellow wire, the PWM ground wire is connected to the black wire, and the pulse frequency is adjusted to about 5000-10000HZ. The air ratio is the speed of regulation.

The following is the actual measurement of the speed under different duty ratios under PWM speed regulation:

Duty cycle: 20% Speed: 598RPM Current: 0.05A

Duty cycle: 30% Speed: 915RPM Current: 0.06A

Duty cycle: 40% Speed: 1188RPM Current: 0.07A

Duty Cycle: 50% Speed: 1433RPM Current: 0.09A

Duty Cycle: 60% Speed: 1665RPM Current: 0.11A

Duty cycle: 70% Speed: 1888RPM Current: 0.14A

Duty cycle: 80% Speed: 2​​092RPM Current: 0.17A

Duty cycle: 90% Speed: 2​​300RPM Current: 0.20A

Duty cycle: 99% Speed: 2​​480RPM Current: 0.23A
