2: the production flow is many and the problems of defective products such as broken wires, damaged wires, elongated wires and the like are easy to occur. The staff in the production process must be skilled workers, and the hands of workers are difficult to get to factories and recruits people with less selectivity.

3: because the winding embedded production line is relatively long, the produced product line is relatively messy. Three lines (vertical lines, flying lines and external lines of a groove) are more in condition, and the existing production process can only be found and processed in a manual mode. There are many uncertainties on the quality of the product produced.

4: in the production process, a plurality of working procedures are finished by personnel and equipment alternately, so that the performance of the produced product is unstable. The main winding and the auxiliary winding are not effectively isolated, and the alternating of the main winding and the auxiliary winding results in low heat dissipation speed of the motor in use. And the embedded enameled wire is not uniform in distribution, and the turn-to-turn probability is very high.

5: the motor produced by the traditional mode is convenient to produce and improves the production efficiency by considering the design from the beginning. The material is excessive from the material point of view, such as the size of the wire package of the enameled wire, the weight of the iron core, and the like.

6: stator insulation produced in a traditional mode is only made aiming at the contact surface of an iron core and an enameled wire, and in actual production, a high-voltage vertical line generated by three wires of the enameled wire is dropped on the iron core or the enameled wire is only partially insulated aiming at the iron core surface outside an insulating layer.
