Abstract

An electric drive system (100) used in an electric vehicle or a hybrid electric vehicle to drive the vehicle's wheels to rotate. The electric drive system (100) includes an electric motor (300). The electric motor (300) includes a housing in which a stator and a rotor are received. A transmission device (400) is operatively coupled to the electric motor (300); and an output shaft (500) is operatively coupled to the transmission device (400). The output shaft (500) extends from the transmission device (400) and is substantially parallel to the rotor's axis of the electric motor (300). The electric drive system (100) also includes an inverter (200) secured over the housing of the electric motor (300) such that the inverter is located between the output shaft (500) and the housing of the electric motor (300).
