Electrical devices using electronmagnetic rotors

Abstract

A device for generating electrical or mechanical output, comprising a rotor coil, a rotor assembly with an axis, and having rotator extensions, a stator coil, and a stator assembly, the stator assembly having two sets of stator flux conductor extensions, the rotator end of the stator flux conductor extension having a stator conductor surface and the interior ends of the first set of stator flux conductor extensions abutting the interior ends of the second stator flux conductor extensions at an abutting junction, wherein rotating the rotor assembly about the axis alternates the rotor assembly between a first and second position in which each of the rotor extension surfaces alternately face the stator conductor surfaces of the first and second set of stator flux conductor extensions. The first and second positions of the rotor assembly lead to the conduction of magnetic flux in the device in opposite paths in the stator assembly generating an output in an output coil. Alternatively, flux conductive extensions can be mounted onto the rotor and an electromagnet or a permanent magnet onto the stator portion. A number of other variations are also shown, including configurations that reduce flux loss between the components. These other variations include a device with a disk-shaped rotor.
