The invention relates to a motor with a high electromagnetic compatibility level, which comprises a stator assembly, a rotor assembly and an end cover assembly, the stator assembly comprises a metal shell, the rotor assembly comprises a rotor iron core and a rotor shaft, the end cover assembly comprises an end cover, the shell comprises a first end provided with a bearing cavity and an open second end opposite to the first end, and the bearing cavity is arranged in the bearing cavity. The motor is further provided with a metal sealing cover, the periphery of the sealing cover is provided with a plurality of holding protruding pieces, the circumferential outer surface of the end cover is provided with a plurality of positioning protrusions, and the edge of the end portion of the second end of the shell is provided with positioning notches used for being matched with the positioning protrusions and holding notches used for being matched with the holding protruding pieces. And the rotor assembly and the end cover assembly are completely encapsulated in the shell through the sealing cover, so that the whole motor is of a metal closed structure. The invention further relates to an automobile seat comprising the motor. By adopting the motor provided by the invention, the electromagnetic radiation of the motor can be suppressed to a greater extent, and a very high EMC level can be obtained.

    本发明涉及一种具有高电磁兼容性水平的电机,其包括定子组件、转子组件和端盖组件,定子组件包括金属的外壳,转子组件包括转子铁芯和转子轴,端盖组件包括端盖,外壳包括设置有轴承腔室的第一端及与第一端相对的敞开的第二端,电机还设置有金属的封盖,封盖在其周缘上设置有多个保持突片,端盖在其周向外表面上设置有多个定位凸起,在外壳的第二端的端部边缘处设置有用于与定位凸起配合的定位缺口及用于与保持突片配合的保持缺口,以通过封盖将转子组件和端盖组件完全地包封在外壳内,从而使电机整体呈金属封闭式结构。本发明还涉及一种包括上述电机的汽车座椅。采用根据本发明的电机,能够更大程度地抑制电机的电磁辐射,获得很高的EMC水平。
