Background
The refrigeration compressor is a core energy consumption component of the refrigeration system, the excellence of the refrigeration system is embodied by the capacity of the compressor, and the most direct and effective means for improving the efficiency of the refrigeration system is to improve the efficiency of the compressor. Refrigeration compressors are used in a wide variety of applications, such as refrigerators, freezers, refreshments, air conditioners, and the like. For a refrigeration compressor, an electric motor is essential. The motor can convert electric energy into mechanical energy and can be divided into an outer rotor motor and an inner rotor motor according to the installation mode of a rotor and a stator of the motor.
However, when the inner rotor motor has the same energy consumption relative to the outer rotor motor, the torque obtained by the inner rotor motor is small, and the starting performance of the motor is obviously influenced. When the inner rotor motor is used in a refrigeration compressor, the energy efficiency ratio of the refrigeration compressor is reduced, material consumption is increased, and production cost is improved. In addition, when a large-volume utilization space is needed, the size of the used refrigeration compressor is large; if a small-sized refrigeration compressor is used, the utilization space of the compressor is reduced, and the compressor is extremely inconvenient in practical application.
The utility model discloses a utility model with publication number CN205960819U, which discloses an outer rotor for a compressor motor, comprising a shell, a base, a magnetic pole, an assembling column and a lamination layer; the number of the magnetic poles and the assembling columns is multiple; the magnetic poles and the assembling columns are sequentially arranged at intervals along the circumferential direction of the inner wall of the shell, and one assembling column is arranged between every two adjacent magnetic poles; the outer shell is connected to the outer side of the edge of the base; the lamination is arranged between the shell and the magnetic pole. Although the outer rotor with the structure overcomes the defects, the following problems exist: the assembly column of the outer rotor with the structure extends a plurality of clamping plates, the shape structure of the assembly column is complex, the machining process is troublesome, and therefore, the technical personnel in the field improve the existing structure of the outer rotor.
