Wiring Maytech Hub Motors to Flier Twin ESC

It took me a while to figure out the wiring for the dual Maytech 90mm sensored hub motors to the Flier twin-motor 120A ESC so I decided to share my findings. Here is the diagram when looking at the bottom of the skateboard:

Wiring Maytech Hub Motor to Flier Twin ESC

Motor Rotation Direction

Each motor has to turn in a different direction if mounted on the opposite sites of the board. This can be achieved by swapping two motor phase wires (B and C) while the hall sensor wiring remains the same for both motors.

Motor Phase Wires

The phase wires of the Maytech hub motors are actually the wires from the stator windings so you have to properly remove the isolation before soldering them to any connectors.

For the counterclockwise rotation or the left wheel when looking from the top of the board:

  • ESC phase A to Maytech red
  • ESC phase B to Maytech black
  • ESC phase C to Maytech yellow

For the clockwise rotation (or the right wheel when looking from the top of the board) you switch ESC phase A and B or yellow and black wires:

  • ESC phase A to Maytech red
  • ESC phase B to Maytech yellow
  • ESC phase C to Maytech black

Hall Sensor Wires

Hall sensor wires use the 6-pin JST ZH connectors (model number JST ZHR-6) which are much smaller than the JST-XH which are used for balance chargers, for example.

  • ESC blue to Maytech green for phase A
  • ESC green to Maytech white for phase B
  • ESC yellow to Maytech yellow for phase C

Here is a photo of the prototype. I’m planning on moving this to a bigger longboard for improved handling since the wheels are so large.
