摘要： An electric drive device includes an electric motor and a speed reducer. The electric motor includes a rotor, a stator, an electrical power converter and a motor housing. The electrical power converter is electrically connected to stator windings of the stator and is configured to supply an electric current to the stator windings. The motor housing receives the rotor, the stator and the electrical power converter. The speed reducer includes: a motor-side rotatable body that is coupled to a shaft of the rotor; and a drive-side rotatable body. The speed reducer is configured to reduce a rotational speed of the drive-side rotatable body relative to a rotational speed of the motor-side rotatable body. The motor housing and the speed reducer are integrally formed together.
