Stator for rotary motor and rotary motor using same

Abstract

The invention relates to a stator for a rotary motor and the rotary motor applying the stator. The stator comprises a stator middle section and two end disc assemblies, namely an end disc A and an end disc B, wherein the stator middle section is a stator core lamination group embedded with a conductor; the stator core lamination group is of a circular cylindrical structure, stator wire embedding grooves are formed in the stator core lamination group, and inner-layer and outer-layer conducting bars are arranged in the stator wire embedding grooves; the two end disc assemblies are installed at the two ends of the stator middle section respectively. Each end disc assembly comprises a plurality of layer disc assemblies, a plurality of wire outlet ends and a plurality of neutral point rings; the number of the leading-out terminals is the same as the phase number of the stator windings; the plurality of layer disc assemblies are coaxially nested; the inner and outer layer conducting bars of the same pole phase group of the same phase are connected in series through the end disc conductor, different pole phase groups of the same phase are connected in parallel to the same phase ring and the same neutral point ring, and the pole phase groups of different phases are connected to different phase rings. According to the invention, the length of the end part of the stator is greatly reduced, so the axial size of the motor is smaller, the structure is more compact, and the manufacturing cost of the stator is reduced.

Description

technical field [0001] The present invention relates to a stator for a rotating electric machine and a rotating electric machine using the same. Background technique [0002] At present, the stator forming coil of the motor is usually designed in the form of a shuttle structure or an involute, which can ensure that the coil manufacturing and stator embedding process are easier to realize, but it also brings two problems: 1) The length of the coil end It accounts for a relatively large proportion of the total axial length of the stator, which is not conducive to saving the axial size of the motor; 2) The embedding and paralleling are in the same process. Many, time-consuming and labor-intensive, not conducive to automatic production of machines. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a design method with a simple and compact structure, which replaces the traditional stator coil paralleling...
