Abstract

The invention discloses a motor applied to a rotary compressor and the compressor with the motor. The motor applied to the rotary compressor comprises a stator and a rotor, wherein the stator comprises a stator iron core and windings, the stator iron core is provided with a plurality of stator grooves, the windings are arranged in the stator grooves, each stator groove only contains same-phase windings with the current in the same direction, the windings in each stator groove comprise a first coil and a second coil, and the ends of the first coils and the ends of the second coils are distributed in the different stator grooves reversely in the peripheral direction of the stator at certain pitch intervals. According to the motor applied to the rotary compressor, the interference space in the intersection process of two phases of windings can be effectively reduced, an receding space needing to be set on the windings on the outer side is reduced, the size of the ends of the windings is reduced, the total length of the windings is shortened, the resistance of the windings is lowered, materials used are saved, and therefore the efficiency of the motor is improved, and meanwhile the cost of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerating equipment, in particular to a motor for a rotary compressor and a compressor having the same. Background technique [0002] In current mass-produced AC motors, when the windings in the same slot are in the same phase, the ends of the windings in each slot are set as one winding, and are distributed in the same stator slot in the same direction. The arrangement of the ends of the windings makes the cross-sectional area of ​​each winding larger. When the ends of the two-phase windings intersect, the interference space is larger, and the outer windings need to set up a larger space for the inner windings. For this reason, the outer windings need Set to a larger size to allow more headroom for the inner winding when shaping. [0003] At the same time, since the resistance of the multi-phase winding of the motor is required to be symmetrical in terms of electrical performance, the inner winding ...
