[0002] The traditional motor structure includes the shaft, rotor assembly, stator core, stator winding, end insulation, casing, front end cover, rear end cover and circuit board. The shaft is connected with the rotor assembly, and the stator core is sleeved outside the rotor assembly. , the end insulation is installed on the end face of the stator core, the stator winding is wound on the stator core, the stator core and the casing are connected together, the front end cover and the rear end cover are installed at both ends of the casing, and the rotating shaft is supported on the front end cover and the casing. On the bearing of the rear end cover, the circuit board is mainly fixed on the end insulation, and the insert piece is protruded from the end insulation, inserted into the socket on the circuit board, and then welded on the circuit board. The other is the stator three-phase Connect the connector with a wire, and then insert it into the connector on the circuit board. These two solutions are not easy to operate, and the cost is high. In addition, it is difficult to realize when the internal space of the motor is small, and the production process is not good.
