A BEARINGLESS AXIAL FLUX MOTOR

 

 

This is an electric motor with very few parts.

No bearings, no brushes and no ferromagnetic cores in the copper coils.

 

The rotor is free floating between two stator plates.

There is no contact between the rotor and stator.

The rotor has a disk shape and doubles as an impeller.

Two stator plates with round holes in the center make the pump housing.

Together these three parts form a simple disk pump.

 

So simple I was able to build a working concept with basic tools.

First working version(proof of concept):

This bearingless motor is basically the same as any other axial flux motor,

but it is configured differently.

And it uses a custom motor controller to drive, center and levitate the rotor.

Minimal parts: lightweight.

No contact between moving parts: minimal wear and minimal shear.

 

Low power consumption.
