Patent ID: 7876019

Claim:
An electrical machine, comprising: a rotor coil; a rotor assembly, the rotor assembly at least partially surrounding the rotor coil, being rotational about an axis, and having first and second sets of rotor extensions, each rotor extension having a top rotor extension surface and a bottom rotor extension surface; wherein each rotor extension has an attached permanent magnet component to hinder direct magnetic flux conduction between the rotor extension surfaces of other proximate rotor extensions; a stator assembly engageable with the rotator assembly, the stator assembly having a first and a second set of stator flux conductor extensions, each of the stator flux conductor extensions having a stator conductor surface; and a stator coil, the stator coil being at least partially encompassed by the stator assembly; wherein each stator flux conductor extension has a rotator end and an interior end, the rotator end having the 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 the rotor assembly is rotatable about the axis between a first and a second position; wherein, in the first position, each of the top rotor extension surfaces of the first set of rotor extensions faces one of the stator conductor surfaces of the first set of stator flux conductor extensions and each of the bottom rotor extension surfaces of the second set of rotor extensions faces one of the stator conductor surfaces of the second set of stator flux conductor extensions, such that magnetic flux is conductable across the abutting junction in a first direction; and wherein, in the second position, each of the top rotor extension surfaces of the second set of rotor extensions faces one of the stator conductor surfaces of the first set of stator flux conductor extensions and each of the bottom rotor extension surfaces of the first set of rotor extensions faces one of the stator conductor surface of the second set of stator flux conductor extensions, such that magnetic flux is conductable across the abutting junction in a second direction that is substantially anti-parallel with the first direction.
