This is a 3-pole DC motor.
The motor was tested at 30V, it draws 1.6A and runs at 6400rpm.
The fan is courtesy of t00tie:
If you decide to build the motor, please note that you won't be able to find the magnets and bearings I used. You will have to redesign the model to fit it to your magnets and ball bearings.
The core slices come from an iron plate that was cut in a water jet cutter. The slices are insulated with magnet wire varnish.
For the windings I used 22 awg magnet wire. That was thick. You could probably use 30 awg wire. Watch here www.youtube.com/watch?v=1673-0Y3fFQ, on how to connect the windings ends.
The commutator is comprised of 3 pieces of a copper tube on a teflon cylinder. The copper pieces are secured on the teflon with epoxy glue.
Brushes are used for the commutation.
The plexiglas base was cut and engraved in a laser cutter.
You will find all the necessary dimensions in the dc_motor.sldprt file.
