1results about How to "Avoid air gap" patented technology

The application discloses a synchronous motor stator structure and a manufacturing method thereof. The synchronous motor stator structure comprises a plurality of stator cores, a plurality of winding assemblies and a glue pouring layer. Each stator core is a circular ring segment. An outer diameter surface of each stator core is at least partially formed with a support portion. The support portion is located at a middle portion of the stator core along the circumferential direction of the stator core. Adjacent two stator cores are inserted into each other along the circumferential direction. The plurality of winding assemblies are sleeved on the stator cores. Two winding assemblies are arranged between any adjacent two support portions. The two winding assemblies are respectively abutted to the two support portions at one end of the winding assemblies which is away from each other. A gap is formed between the two winding assemblies at one end of the winding assemblies which is close to each other. The plurality of winding assemblies and the plurality of stator cores are matched to form a ring structure. The glue pouring layer is annular and covers the ring structure. The glue pouring layer does not fill the gap. Through the above arrangement, the occurrence of air corona caused by excessive local electric field strength can be avoided, and the service life of the synchronous motor stator structure is improved.
