The ongoing development of a DIY Axial Flux DC motor is shown below:

The Axial Flux motor is based on very strong (N42) general purpose neodymium magnets such these:

The magnet size is 22mm x 10mm.

The mechanical design is based on a “Mecano” stile approach:

A suitable Electronic PWM controller has been built for motor testing purposes:

The associated electronics is shown below:

A Test-Bench for the evaluation of the motor has been built as shown:

The Motor Concept is illustrated below:

The rotor contains 4 magnets arranged as shown:

There are two coil panels. The orientation of the coils are shown below:

The coils are made up using 1mm diameter copper coil wire, 100 turns.

An optical sensor is used to determine the rotor position.

The motor concept is shown below:
