Stator for motor, permanent-magnet motor with stator and compressor

Abstract

The invention discloses a stator for a motor, a permanent-magnet motor with the stator and a compressor. The stator comprises a stator core, a plurality of pairs of wiring conductors and a stator winding, wherein the stator core comprises a yoke part and a plurality of tooth parts, the plurality of pairs of wiring conductors are arranged at the yoke part in an insulation way, each pair of wiring conductors comprises an incoming line wiring conductor and an outgoing line wiring conductor which are arranged at two sides of each tooth part, the stator winding comprises a transition line and a plurality of coils, each coil is provided with an incoming line wiring end and an outgoing line wiring end which are respectively led out of the two sides of each tooth part, the incoming line wiring endand the corresponding incoming line wiring conductor are arranged at the same side of the tooth part and are connected, the outgoing line wiring end and the corresponding outgoing line wiring conductor are arranged at the same side of the tooth part and are connected, two same coils adjacent to each other are respectively a first coil and a second coil, and the outgoing line wiring conductor connected with the first coil and the incoming line wiring conductor connected with the second coil are arranged at intervals and are connected by the transition line. With the stator disclosed by the embodiment of the invention, the problem of line crossing in a groove is favorably solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator for a motor, a permanent magnet motor with the stator and a compressor. Background technique [0002] With the development of the modern economy, the requirements for the cost performance (performance / cost) of air conditioners are getting higher and higher. The high energy efficiency and low cost of compressors as the core components of air conditioners have become the subject of industry research. -Motors put forward higher requirements. [0003] In related technologies, the main idea of ​​improving the cost performance of motors is to miniaturize the motor, that is, to minimize the volume of the motor when the power output and performance meet the requirements, so as to reduce the cost of the motor. [0004] From the perspective of electromagnetic analysis, when the same slot and pole match the same material, the performance of the motor is limited; if the slot and pol...

Problems solved by technology

[0005] However, there is a problem with the multi-slot and multi-pole slot-pole cooperation, that is, the winding wire will cross the wire in the slot, so for the centralized winding, there is a cross-wire in the gap between the coil and the coil, and the winding process The wire is easily scratched by the winding nozzle, and because of the existence of the transition wire, the manufacturing cycle will be slowed down, which will affect the efficiency of the motor manufacturing; especially for the segmented motor, if there is a cross wire in the slot, it will affect the full rate of the motor slot Further improve
