Abstract

Disclosed is a high-efficient motor used for a scroll compressor. The high-efficient motor comprises a stator iron core and a rotor, wherein the stator iron core is provided with a winding and a connecting line; the coil of the winding is formed by composite enamelled wires in a winding manner; the stator iron core is formed by a group of stator punching sheets with stator grooves in a welding, laminating and pressing manner; the rotor is formed by a group of rotor punching sheets with rotor grooves in an aluminum-casting, laminating and pressing manner; rotor end rings are arranged at the two ends of the rotor respectively; the stator groove is 19-20mm in thickness, 4.5-5mm in radius and has a circular bottom; and the number of turns of the composite enamelled wires in each stator groove is 41. The rotor is directly mounted on a rotary shaft of the scroll compressor, so that the structure of the motor is simplified, the size of the motor is reduced, and the capacity margin of the motor is improved; meanwhile, the parts are reduced and the cost is lowered; and in addition, optimized design is adopted, so that the loss can be lowered, and the efficiency of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-efficiency motor for scroll compressors. Background technique [0002] Due to the advantages of high energy efficiency, compact structure, low noise, and simple operation, at present, scroll refrigeration compressors are gradually replacing traditional semi-hermetic piston compressors, which is a development trend. The main starting point to improve the energy efficiency ratio of the compressor is the motor. However, due to the relatively compact structure of the scroll compressor, it is determined that the space for the motor is limited, and it is very difficult to further improve the efficiency of the motor. For this reason, many companies In the process of exploration, but the effect is not good. [0003] In addition, in addition to the rotor and stator, most motors also have casings, end covers, bearings and rotor shafts. As an independent whole, they are connected to ...
