Abstract

The present disclosure relates to an electric motor having an integral gearbox, the electric motor may include: a stator having a first member disposed on an inner circumferential surface of an enclosure to generate an electromagnetic force; a rotor having a second member disposed on an outer circumferential surface to face an inner circumferential surface of the stator to generate an electromagnetic force together with the first member; a gear assembly provided with gear teeth on an inner circumferential surface of the rotor and disposed within the rotor; and a control unit that controls the gear assembly, where the gear assembly includes one or more gear plates that rotate as the rotor rotates; a connection gear disposed to be selectively coupled to any one of the one or more gear plates; and an output shaft that rotates together with rotation of the connection gear to transmit a rotational force to the outside, and the control unit controls the moving portion according to a shift signal to allow the connection gear to be coupled with or decoupled from any one of the one or more gear plates.

Description

technical field [0001] The present disclosure relates to electric motors with integral gearboxes, and more particularly, to electric motors with integral gearboxes capable of including one or more variable speed gear plates inside the electric motor. Background technique [0002] In recent years, with increasing interest and awareness of environmental issues, the automotive industry paradigm intends to improve fuel efficiency based on strengthening various environmental regulations aimed at reducing greenhouse gas emissions. [0003] Therefore, from the emergence of hybrid vehicles, the development and commercialization of electric vehicles such as plug-in hybrid electric vehicles, electric vehicles, and hydrogen fuel cell vehicles are gradually expanding globally in recent years. [0004] One of the key components of this electric-based vehicle is the drive motor. [0005] Currently, the structure of a conventional engine vehicle is used, and an electric motor provides pow...
