On a brushless motor, there is no + and - (positive and negative). Instead, there are three "phases," one for each of the three wires. To repeat:
There is no + and - on a brushless motor.
There are three wires on a brushless motor and three wires on the
motor side of a brushless ESC. You connect the three motor wires to the three wires coming from the motor side of the brushless ESC.
On the
battery side of a brushless ESC, there are two wires, same as on brushed ESC. These are + and - (positive and negative) and connect to the + and - terminals of the battery.
See the diagram below.
