  • Variable transmission apparatus
    Patent number: 5833564
    Abstract: A variable transmission mechanism, particularly for the automatic transmission of a vehicle, comprises a driven rotor (22) having windings to which a variable DC supply is fed, and an armature rotor (10) in electromagnetic cooperation with the driven rotor. The rotors are connected to an epicyclic gear train (14) which is also connected to an output shaft, the arrangement being such that an increase in power supply to the driven rotor increases the torque between the rotors and enables the speed of the output shaft to be increased.
