The specification of this brushless motor is 3830, the outer diameter of the motor is 37.6 mm, which is approximately 38;
30 refers to the diameter of the stator, that is, the outer diameter of the coil is 30 mm.
The motor's metal casing and shaft are connected together. When powered, they rotate synchronously, which is the outer rotor.
There are 3 wires, red wire positive, black wire negative, and blue wire PWM speed regulation. Compared with ordinary two-wire motors,
this one has an additional speed regulation function and is more cost-effective!

①Simple wiring method (no speed control board required):
Connect the red wire to the positive pole of the DC 12V power supply and the black wire to the negative pole
. The motor will rotate at the highest speed. (No-load speed is about 3600 rpm)
Note: The motor has a built-in reverse connection protection function. Reverse connection of the positive and negative poles will not burn the motor,
but it will not work.
②Wiring method using speed control board: (It is easier to understand by looking at the picture)
You need to purchase a brushless motor PWM speed control board and prepare a DC12V power supply;
The red wire of the motor is connected to the VCC of the speed control board, the black wire is connected to GND, and the blue wire is connected to PWM;
The 8-24V + sign of the speed control board is connected to the positive pole of DC 12V, and
the 8-24V - sign of the speed control board is connected to the negative pole of DC 12V;
You are done. Just turn the speed potentiometer to adjust the motor speed.
Speed range: about 300-3600 rpm,
no-load current range: about 22-77 mA.
