ABSTRACT:
A motor drive apparatus for an electric vehicle has a case attached to a vehicle body; an output axle which rotates relative to the case; an electric motor having a magneto stator secured to an inside wall of the case and a rotor which faces the magneto stator with a predetermined clearance and rotates relative to the case; and a planetary gear unit provided inside of the rotor and consisting of three components of a sun gear, a ring gear and a carrier. The electric motor speed is output from the output axle through the planetary gear unit.
