Possible AT brushed electric engine/alternator
3D model of AT brushed engine/alternator (AC-version)
3D model of AT brushed engine/dynamo (DC-version)
The AT brushed electric motor/alternator is a device that can generate either mechanical movement (rotation) or electricity; depending on which of the two is supplied to the device.
[edit] Design
Depending on the direction of the windings, each electromagnet gets a polarity when electricity is run trough it; however by reversing the flow of this, we can however alternate the polarity
