ABSTRACT:
A driving system for an electric vehicle which drives wheels thereof with the aid of an AC motor via an inverter while a battery is used as a power source is constructed such that the primary side and the secondary side of the AC motor are rotatably supported in a motor frame. One of the primary and the secondary sides of the AC motor is operatively connected to a power transmission shaft for one of a left-hand wheel and a right-hand wheel via a reversible type speed reducing mechanism while the direction of rotation of the power transmission shaft is reversed relative to that of the one of the primary and secondary sides. The other one of the primary and the secondary sides of the AC motor is operatively connected to a power transmission shaft for the other one of the wheels via a non-reversible type speed reducing mechanism while the direction of rotation of the power transmission shaft is kept unchanged relative to that of the other one of the primary and secondary sides. Electricity from the battery is fed to the coil on the primary side of the AC motor via the inverter and a slip ring.
