Abstract
A permanent magnet assembly is disclosed that utilizes at least two rotating magnet subassemblies, and first and second stationary magnet subassemblies arranged so that their magnetic vectors oppose each other. At a first rotational position of the rotating magnet subassemblies, the magnetic vectors of the rotating magnet subassemblies align with the magnetic vector of the first stationary magnet subassembly and oppose the magnetic vector of the second stationary magnet subassembly. At a second rotational position, the magnetic vectors of the rotating magnet subassemblies are reversed, thereby aligning with the magnetic vector of the second stationary magnet subassembly and opposing the magnetic vector of the first stationary magnet subassembly. By locating air gap portions where the magnetic vectors of the rotating magnetic subassemblies meet the magnetic vectors of the stationary magnetic subassemblies, the air gap portions are subjected to a time-varying magnetic flux density.
