Micromotor stator assembly and centrifugal pump

The utility model relates to a micro-motor stator assembly and a centrifugal pump, which comprise an iron core of a tooth part with a plurality of teeth which are sequentially connected at a yoke part, a framework, a centralized winding and an insertion piece, the first insertion piece and the fourth insertion piece are located on the framework where the head tooth and the tail tooth of the tooth part are located, the second insertion piece is located on the framework where the second tooth or the third tooth is located, and the third insertion piece is located on the framework where the penultimate tooth or the penultimate tooth is located. According to the micromotor stator assembly of the utility model, through changing the connection of the winding and the ingenious arrangement of the position of the insertion sheet, a winding machine can complete the whole winding process uninterruptedly only through one-time wire incoming, and after winding is completed, a phase-crossing enameled wire connected with the
