Magnetic suspension motor for refrigerant conveying

Abstract

The invention discloses a magnetic suspension motor for refrigerant conveying. The magnetic suspension motor comprises a machine shell and a rotating shaft assembly, a front end cover is installed at the front end of the machine shell, a rear end cover is installed at the rear end of the machine shell, and an automatic door is arranged on the front end cover; and a flow guide disc, a pressurizing shell, an axial displacement detection assembly for detecting the axial displacement of the rotating shaft assembly, a front magnetic bearing assembly, a stator assembly and a rear magnetic bearing assembly are sequentially installed in the machine shell from front to back. The rotating shaft assembly comprises a mandrel a, a mandrel b, a connecting sleeve and magnetic steel. The mandrel a sequentially penetrates through the flow guide disc, the pressurizing shell, the axial displacement detection assembly and the inner ring of a front bearing assembly. The magnetic suspension motor has the beneficial effects that radial displacement adjustment and axial displacement adjustment of the rotating shaft are both of a hybrid excitation structure, efficient conveying of refrigerants is guaranteed, meanwhile, energy consumption is reduced, and the occupied space is small.

Description

technical field [0001] The invention relates to refrigerant transportation of a central air conditioner, in particular to a magnetic levitation motor for refrigerant transportation. Background technique [0002] The magnetic levitation motor has a high speed, so it can be used as an additional device in many fields, such as in the central air conditioner, the existing central air conditioner usually uses a conventional power pump to deliver wind, especially in severe cold and hot weather, Since the power of the power pump does not meet the requirements, it will lead to low cooling or heating efficiency of the central air conditioner, and high energy consumption. [0003] After long-term research by the inventor, a magnetic levitation motor using hybrid excitation was invented to replace the existing power pump, so as to realize the pressurization and transportation of air with low energy consumption and high efficiency. Contents of the invention [0004] The object of the...
