ESC-Motor Wiring

The polarity and connection is indicated in the following image.

The section of the cables must be dimensioned according to input/output max power

Note

The polarity connection of the input must be respected, otherwise a short circuit may occour. Connection of the phases can be done freely, however, it will affect the direction of rotation of the motor.
