Description

[0002] The stator core is an important part of the stator and the main component of the motor magnetic circuit. It is composed of fan-shaped pieces, ventilation slot pieces, positioning ribs, upper and lower tooth pressure plates, tension bolts and support plates. The stator core is punched into fan-shaped pieces with silicon steel sheets and stacked on the positioning ribs. The positioning ribs are welded to the ring plate of the machine base through the support plate, and the core is compressed into a whole through the upper and lower tooth pressure plates with tension bolts. The stator core is also the part where the winding is placed. When the generator is running, the core will be subjected to the combined effects of mechanical force, thermal stress and electromagnetic force.

[0003] After the stator core is formed, thermal grease needs to be applied to the heat dissipation surface of the stator core, and then a thin copper sheet is installed, and finally assembled with the motor housing. The high thermal conductivity of the thermal grease is used to exchange the heat energy generated during the operation of the motor through the thin copper sheet and the cooling channel inside the motor housing to achieve thermal balance during the operation of the motor. However, due to the large heat dissipation surface of the stator core, it is difficult to ensure the consistency of thickness and surface flatness of the thermal grease, making production control difficult.
