The invention discloses a stator assembly, a motor and a power-assisted bicycle, the stator assembly comprises a stator assembly and a busbar assembly, the stator assembly is provided with a plurality of block stator iron cores and block stator windings wound on the block stator iron cores, each block stator winding is provided with two wiring ends, and the two wiring ends are connected with the busbar assembly. The busbar assembly is installed at one end of the stator assembly in the axial direction, the busbar assembly is provided with multiple layers of bus bars, each bus bar is provided with a plurality of connecting parts, the stator assembly is further provided with a gap bridge connecting piece, the gap bridge connecting piece is connected with one wiring end of each of the at least two block stator windings, and the connecting parts are connected with the other wiring ends of the stator assembly in a one-to-one correspondence mode. Since part of the terminals are connected through the gap bridge connecting pieces, the number of the connecting parts can be reduced, the number of layers of the bus bars is further reduced, the axial size of the bus bar assembly is reduced, and the axial height of the stator assembly is further reduced. The axial size and the volume of the motor are reduced, and the compatibility and the adaptability of the motor and the whole machine are improved.

    本发明公开了定子总成、电机及助力自行车,其中定子总成包括定子组件和汇流排组件,定子组件设有多个分块定子铁芯,以及绕设于分块定子铁芯的分块定子绕组,每个分块定子绕组具有两个接线端,汇流排组件安装于定子组件沿轴向的一端,汇流排组件设有多层汇流条,汇流条具有多个连接部,其中,定子组件还设有过桥连接件,过桥连接件连接至少两个分块定子绕组的各一接线端,连接部与定子组件其余的接线端一一对应连接,由于部分接线端通过过桥连接件连接,从而能够减少连接部的数量,进而减少汇流条的层数,降低汇流排组件的轴向尺寸,进而降低定子总成的轴向高度。有利于降低电机的轴向尺寸和体积,提高电机和整机的兼容适配性。
