In preferred embodiment of the utility model, the number of stator slots that is provided with in the described stator core is 9.
In preferred embodiment of the utility model, enamelled wire coiling group is set in the described stator slot.
In preferred embodiment of the utility model, described stator winding group distributes for the concentric type winding.
In preferred embodiment of the utility model, described enamelled wire is copper enamelled wire or aluminium enamel-covered wire, and line directly is 0.3mm-0.9mm, and temperature resistant grade is 155-220 ℃.
In preferred embodiment of the utility model, described plastic end cover material adopts PBT, a kind of in PET or the nylon.
In preferred embodiment of the utility model, insert insulating paper between each stator slot of described stator core.
In preferred embodiment of the utility model, location hole is set on the described stator core, totally 4 holes, the aperture is 5.5mm-7.5mm.
The beneficial effects of the utility model are:
1, the multilayer concentric structure of the utility model location notch internal stator winding can reduce harmonic component, improves the quality of power supply and performance, improvement stability.
2, the utility model employing copper enamelled wire or alumin(i)um paint guarantor line latitude are stator winding, and temperature resistant grade is 180-220 ℃, and is safe in utilization, simultaneously insulating paper is set between stator slot, phase insulation, and the fail safe that has further improved motor stator, and simple to operate; Stator end is attractive in appearance, and is orderly.
3, the utility model adopts the motor of this stator structure can use the frequency conversion voltage of 0-999Hz, is to be mainly used in the energy-saving and frequency-variable motor stator that is used for freezer compressor, good insulation preformance, motor long service life.
