Summary of the invention
The problems such as the purpose of this utility model is exactly that will to solve traditional rotor of refrigeration compressor punching electric efficiency low, and production cost is high, and manufacturing technique requirent is high, provide a kind of rotor punching of modified model refrigerant compressor.
Concrete scheme of the present utility model is: the rotor punching for existing refrigerant compressor improves, the outline of described rotor punching is circular, centre has circular hole, circumferential periphery along rotor punching is processed with several rotor slot shapes, spacing between adjacent two flute profiles is the groove facewidth, circular hole cylindrical is that rotor yoke is high to the distance of bottom land, and the groove facewidth of described rotor punching is 1.7-2.1mm, and rotor yoke height is 11-12mm.
Groove facewidth the best of rotor punching described in the utility model is 2.0mm, and the high the best of rotor yoke is 11.65mm.
The top of flute profile described in the utility model is isosceles triangle, and groove top width is 2.4-3.0mm, and bottom land is arc, and bottom radius is 1.0-1.2mm.
The top width of groove described in the utility model the best is 2.6mm, and bottom radius the best is 1.1mm.
The utility model is by AnsoftRmxprt optimal design rotor punching, motor rotor punching sheet flute profile is improved, increase the rotor facewidth and rotor yoke high, improve rotor tooth yoke portion magnetic close, rotor punching teeth portion magnetic is close and yoke portion magnetic is close tends to balance, and magnetic flux distribution is tending towards reasonable, reduce motor flux leakage and noise, while minimizing rotor aluminum consumption, improve electric efficiency, and the requirement of other performance of motor can be met.
