Patent ID: 7029412

Claim:
An electro-mechanical power transmission equipment, comprising: a casing, a power transfer arrangement inside the casing and having a power-in axle and a power-out axle, and between the power-in axle and the power-out axle, a) an electricity generating and torque-transferring main generator arrangement rotated by the power-in axle, and b) an electric motor arrangement that rotates the power-out axle, wherein incoming rotational power of the power-in axle is divided by a first planetary gear set between the power-out axle and the main generator arrangement, wherein, for enhanced electricity generation, the main generator arrangement is equipped with a combination of speed up gearing and first and second clutches, which combination greatly increases an air gap velocity between magnetic field producing elements of the main generator arrangement, wherein, the electric motor arrangement, an armature winding and a rotor thereof are counter-revolving in relation to one another, and between the rotor and the power-out axle there is reduction gear arrangement transferring multiplied torque to the power-out axle, and wherein, in a power transmission process, all torques and counter-torques of both the main generator arrangement and the electric motor arrangement are directed to rotate the power-out axle in an intended direction of the power-out axle.
