Abstract
A driving motor system and a driving system of an electric mobility are provided. The driving motor system may comprise: an inverter configured to receive DC power and convert the DC power into AC power; a motor configured to provide driving force; and a reducer configured to increase the driving force provided by the motor and transmit the driving force to a wheel of the electric mobility, wherein the motor and the reducer are installed inside a motor housing.
Claims14
A driving motor system of an electric mobility, comprising:
- an inverter configured to receive DC power and convert the DC power into AC power;
- a motor configured to provide driving force;
- and
- a reducer configured to increase the driving force provided by the motor and transmit the driving force to a wheel of the electric mobility,
- wherein the motor and the reducer are installed inside a motor housing, the reducer comprises an input gear and an output gear, the input gear comprises a shaft which functions as a rotor shaft of the motor, and the shaft of the input gear and a shaft of the output gear are coaxial, the reducer further comprises at least one planetary gear, and the at least one planetary gear comprises a first gear portion which is directly engaged with the input gear and a second gear portion which is directly engaged with the output gear to receive the driving force from the input gear and transmit the driving force to the output gear, and
- wherein the shaft of the output gear comprises a recess and the shaft of the input gear is extended in an axial direction so as to be overlapped with the output gear within the recess, and a first bearing for concentrically supporting the input gear and the output gear is provided within the recess between the shaft of the input gear and the shaft of the output gear.
