Wiring of Brushless Electric Vehicle Controller

The Hall voltage input of the handlebar is 5V, and the output is about1.2-4.2V. This current is very small, so don't move, otherwise it will affect the normal riding of the car. Most cars have 12V converters, some under the seat and some in the headlight housing. The converter * * * has three wires, the red line is 48V input, the black line is negative, and the yellow line is 65438+.

Wiring Description of Brushless Electric Vehicle Controller

1, power input.

The thick red line is the positive end of the power supply, the black line is the negative end of the power supply, and the thin orange line is the electric door lock.

2. Motor phase (U, V, W output).

The yellow thick line is u, the green thick line is v, and the blue thick line is w.

3. Rotation signal input.

The red thin wire is the +5V power supply, the green thin wire is the signal input of the handle, and the black thin wire is the ground wire.

4. Motor Hall (A, B and C inputs).

The red thin wire is the +5V power supply, and the black thin wire is the ground wire.

The thin yellow line is a, the thin green line is b, and the thin blue line is C.

5. Brake (flexible EABS+ mechanical brake).

Thin yellow lines are flexible EABS；; ; The blue thin line is mechanical braking (advanced braking:+12V).

The thin black line is the ground wire (low level braking).

6. sensors.

The red thin wire is the +5V power supply, the black thin wire is the grounding wire, and the green thin wire is the sensor signal input.

7. Instrument (speed): purple thin line.

8. Cruise: thin brown line.

9. Speed limit: thin gray line.

10, automatic identification switch line: thin yellow line.
