Problems solved by technology
However, there are still many problems in the current segmented iron core structure. For example, the loss of the magnetic field at the splicing part is large, which leads to a certain decrease in the efficiency of the motor. The harmonics of the gap magnetic field increase, and the vibration and noise of the motor deteriorate

Abstract
The invention provides a combined stator core, a motor, a compressor and an air conditioner. The stator core comprises a first iron core punching sheet group and a second iron core punching sheet group which are arranged along the axial direction of the stator core. The first iron core punching sheet group comprises a plurality of spliced first punching sheets; the second iron core punching sheetgroup comprises a plurality of spliced second punching sheets, the first punching sheets and the second punching sheets are connected through hinge points, the stator iron core after hinge combinationis provided with an annular yoke part and tooth parts, the annular yoke part is provided with yoke part areas corresponding to the tooth parts along the radial outward direction of the stator iron core, and the hinge points are arranged in the yoke part areas. According to the invention, the punching sheet hinge points are arranged in the annular yoke part area corresponding to the tooth parts, the structural strength of the hinge combined stator core is improved, influence on the magnetic circuit of the stator yoke part is reduced, the coaxiality of the stator core is improved, the air gap magnetic field harmonic wave is reduced, the motor noise is reduced, and the motor efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a combined stator core, motor, compressor and air conditioner. Background technique [0002] Environmental protection and energy conservation are important concerns for the sustainable development of society. With the improvement of the quality of life, the popularity of refrigeration and air-conditioning has increased. According to statistics, the electricity consumption of refrigeration and air-conditioning accounts for 20% of the annual electricity consumption nationwide. As an important component of refrigeration and air-conditioning, compressors consume the largest proportion of energy. Therefore, reducing the loss and improving the efficiency of the motor in the compressor has become a key issue. Further improving the motor slot full rate will help reduce the winding resistance, thereby reducing the copper loss of the motor and improving the efficie...
