The invention provides a novel power-assisted steering electric drive assembly of a wire outlet structure. The power-assisted steering electric drive assembly comprises a rotor, a stator, tracking magnetic pole magnetic steel, a machine shell and a PCB. The rotor is installed in the stator, the tracking magnetic pole magnetic steel is fixed at the bottom end of the rotor, the stator is fixed in the machine shell, and the PCB is fixed at the bottom end of the machine shell. A partition plate is arranged at the position, between the PCB and the stator, in the machine shell, and the tracking magnetic pole magnetic steel is located between the partition plate and the PCB. One side of a PCB control panel is fixed on the machine shell, and the other side of the PCB control panel is sealed by a controller cover plate and then is integrated with the motor body, so that an independent mounting space is not needed any more, the occupied space is smaller, and the part management and assembly costis saved; in addition, the leading-out wire of the motor body is directly led out by an enameled wire without a mounting bracket, a copper bar and the like, so that the parts are fewer, the weight islight, the manufacturing cost is lower and the quality is more reliable.

    本发明提供了一种新型出线结构的转向助力电驱动总成,包括转子、定子、跟踪磁极磁钢、机壳、PCB板;所述转子安装在定子中,转子底端固定跟踪磁极磁钢,定子固定在机壳内,机壳底端固定有PCB板;在机壳内,位于PCB板和定子之间的位置有分隔板,跟踪磁极磁钢位于该分隔板和PCB板之间。本发明PCB控制板一侧固定于机壳上,另一侧采用控制器盖板密封后与电机本体集成于一体,不再需要单独的安装空间,占用空间更小,节省零件管理和装配成本;另外电机本体引出线直接采用漆包线引出,不再需要安装支架、铜排等,零件更少,重量轻,制造成本更低,质量更可靠。
