What are the advantages of trimming the stator?
Reply 15# Reply to the old five. In the air-conditioning compressor, whether it is single-phase or three-phase, it must be trimmed. 1. Because the compressors of household air conditioners are all designed with high pressure, in terms of rotation, the lower pump body and the upper motor are used. The refrigerant mainly flows upward through the gap between the stator and the rotor and the air holes of the rotor. The oil in the lower part of the pump body is mainly retained through the gap between the stator and the shell. Therefore, the fine adjustment of the three-phase motor of air conditioning compressor is mainly for oil return. (Overflow area has an important influence on oil return) 2. Of course, when stamping silicon steel, trimming can improve the utilization rate of silicon steel. View original post >>
