Motor

This is the motors rotor. It has 36 permanent magnets along the outside.

The permanent magnets in addition to powering the motor also turn the Hall effect sensors on and off.

Under the rotor are the coils.

There are 9 coils for each phase.

There are 3 phases for a total of 27 coils.

Inside of motor drum

There are a total of 36 of these magnets inside the rotor drum.

Magnets inside motor drug

There are a total of 36 of these magnets inside the rotor drum.

27 coils or electromagnets - 9 for each of the 3 phases

The "Y", "B" and "R" are the color of the wire the electromagnet is attached to. "Y" is the yellow wire, "R" is the red wire and "B" is the blue wire.

The 9 coils for each phase are wired in series.

Hall effect sensors - one sensor for each of the 3 phases

Bread board to test Hall effect sensort

This is a breadboard I designed to show us when the Hall effect sensor turns on and off.

Each phase, A, B, C or 1, 2, 3 has a Hall effect sensor to tell when the phase should receive electricity.

These LEDs just light up when the appropriate Hall effect sensor turns on or off.
