Abstract
An electric drive unit includes an inverter, a stator that receives an AC current from the inverter and forms a magnetic field, a rotor rotated by the magnetic field formed by the stator, a shaft that protrudes into both sides in an axial direction of the rotor and moves in synchronization with the rotor, an inverter casing that stores the inverter in a galvanic isolation state, and a motor housing. The motor housing stores the stator and the rotor in a galvanic isolation state, rotatably supports one end of the shaft using a first bearing, and rotatably supports the other end of the shaft using a second bearing. The inverter and the inverter casing are arranged in an inner side from a pair of bearings including the first and second bearings.
