To provide an electric drive device capable of outputting high output torque with small rotational inertia that becomes a load in reverse driving.SOLUTION: A electric drive device 100 includes an eccentric motion input reduction gear (planetary gear 14 and ring gear 16), a rotor 12 having a magnetomotive force source, and a stator 10 having a magnetomotive force source, and the rotor 12 is constrained to rotate on its axis and is only capable of revolving motion with respect to the stator 10. The stator 10 generates a rotating magnetic field with a frequency different from the rotation frequency of the rotor 12, the orbital motion of the rotor 12 is driven by the rotating magnetic field generated by the stator 10, and the orbital motion of the rotor 12 is converted into rotary motion of the output shaft by the reduction gear.SELECTED DRAWING: Figure 1 【課題】逆駆動時の負荷となる回転慣性が小さく、高い出力トルクを出力可能な電動駆動装置を提供する。【解決手段】偏心運動入力の減速機（プラネタリギア１４及びリングギア１６）と、起磁力源を有するロータ１２と、起磁力源を有するステータ１０と、を備え、ロータ１２は、自転運動が拘束されており、ステータ１０に対して公転運動のみが可能であり、ステータ１０は、ロータ１２の回転周波数とは異なる周波数の回転磁界を発生させ、ステータ１０によって発生された回転磁界によりロータ１２の公転運動が駆動され、ロータ１２の公転運動を減速機により出力軸の回転運動に変換する電動駆動装置１００とする。【選択図】図１
