The invention discloses a new energy automobile power assembly system based on a brushless permanent magnet motor, and relates to the technical field of new energy automobile power assemblies. The motor comprises a box body, heat dissipation openings are formed in the front face and the back face of the box body, a plurality of baffles are fixed in the heat dissipation openings, a motor body is fixedly installed at the bottom of the inner wall of the box body through a frame plate, a heat dissipation fan is embedded in the right side of the box body, the motor further comprises a protection device, and the protection device comprises a circle run-out prevention mechanism. Through the arrangement of the protection device, the elastic telescopic plate buffers vibration force borne by the motor body, so that the motor body is protected, and meanwhile, under the spring elastic force effect of a buffer spring, the buffer spring drives a lantern ring to buffer circular run-out at a rotating shaft of the motor body; therefore, the problem that the use of the motor main body is affected by circle run-out at the rotating shaft of the motor main body is avoided, and the service life of the motor main body is prolonged.

    本发明公开了一种基于无刷永磁电机的新能源汽车动力总成系统,涉及新能源汽车动力总成技术领域。本发明包括箱体,所述箱体的正面和背面均开设有散热口,所述散热口的内部固定有若干个挡板,所述箱体的内壁底部通过架板固定安装有电机主体,所述箱体的右侧嵌设有散热风扇,还包括防护装置,防护装置包括防圆跳动机构。本发明通过防护装置的设置,使得弹性伸缩板对电机主体受到的振动力进行缓冲,从而实现对电机主体进行保护,同时在缓冲弹簧的弹簧弹力作用下,缓冲弹簧带动套环对电机主体转轴处发生圆跳动进行缓冲,从而避免了电机主体转轴处发生圆跳动,影响电机主体使用的问题,从而提高了电机主体的使用寿命。
