Abstract

A power transmission system is provided, suitable e.g. for driving an electrical vehicle from a power supply such as on an electrochemical battery. The system provides an electric motor having two relatively rotatable motor portions. Each motor portion is relatively rotatable to an anchorage or mounting for the motor, coaxially with the axis of rotation between the motor portions. One motor portion is provided with the power output for the system and the other motor portion is drivingly connected to a hydrostatic machine capable of acting as a pump or motor which is in liquid flow communication with a hydrostatic accumulator and liquid source.
