Patent ID: 8653677

Claim:
An electromagnetic, continuously variable transmission power split turbo compound, comprising: a turbo compound turbine driven by exhaust gases from an internal combustion engine; and a power split device comprising a magnetic gear arrangement, the magnetic gear arrangement comprising a high speed rotor comprising a first quantity of permanent magnets, a low speed rotor comprising a second quantity of permanent magnets, and a plural pole rotor between the high speed rotor and the low speed rotor, a first rotor of the high speed rotor, the low speed rotor, and the plural pole rotor comprising a mechanical input drive adapted to be driven by the turbine, a second rotor of the high speed rotor, the low speed rotor, and the plural pole rotor comprising a mechanical output drive, and a third rotor of the high speed rotor, the low speed rotor, and the plural pole rotor being unconnected to a mechanical drive and comprising a controlling rotor for controlling a ratio of input drive angular velocity to output drive angular velocity.
