Abstract
The invention relates to an improved stator of a motor, which comprises a stator core, a stator winding and groove insulation paper. The improved stator is characterized in that the two end faces of the stator core are respectively fastened with an insulating ring which is made of insulating materials and consistent with the stator core in physical dimension and notch. The groove insulation paper is arranged in a stator groove, and the both ends of the insulation paper do not extend out of the end face of the insulating ring. The improved stator has the advantages that as the groove insulation paper is not higher than the end face of the insulating ring, and the end connected part of the stator winding is short, the stator is convenient to be reshaped so as to improve the insulating strength, save 10-20% of copper, reduce the leakage magnetic flux and leakage reactance of the end connected part of the stator winding of the motor, improve the efficiency of the motor and reduce the production cost.
Description
Technical field
The present invention relates to a kind of motor stator, belong to the stator improvement of electric rotating machine, particularly a kind of improved type electric machine stator.
Technical background
Present motor stator posts the trim ring of hot rolled steel plate moulding in the both ends of the surface of stator core; Motor stator slot outlet insulation is the slot liner paper of slot liner or film to be extended an end exceed the groove outlet; As groove outlet insulation,, thereby make that motor windings rolls off the production line, shaping, shortening end coil bring difficulty because of it is soft insulation. and the trim ring at stator core two ends is when motor moves; Produce eddy current therein. make its heating be higher than stator core; Cause the loss of electric machine and damage stator slot outlet insulation, because soft insulated motor stator winding will have one section straightway not damage groove outlet insulation with assurance after going out notch, thereby the termination portion of motor stator winding is long more; The required copper cash of winding is many more, and brow leakage is logical also just strong more. and make the loss of electric machine too high.
Summary of the invention
The present invention is in order to address the above problem, and a kind of improved type electric machine stator is provided, and its stator winding termination portion is short, does not need slot liner paper to extend the groove outlet, improves groove outlet dielectric strength, saves the winding copper material, improves a kind of motor stator of electric efficiency.
The present invention is for realizing above-mentioned purpose; Adopt following technical scheme: a kind of improved type electric machine stator; Comprise stator core, stator winding, slot liner paper; Be characterized in being fastened with physical dimension, a notch dead ring consistent with stator core of processing with insulating material respectively at two end faces of stator core, the dead ring end face is not stretched out at slot liner paper two ends in stator slot.
Beneficial effect of the present invention: by motor stator provided by the invention; Because slot liner paper does not exceed the dead ring end face, the stator winding termination portion is short, the convenient dielectric strength that improves of shaping; Can practice thrift the copper material of 8-15%; Reduce motor stator winding termination section leakage flux and leakage reactance, improve efficiency of motor, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 one dead rings, 2 one stator windings, 3 one slot liner paper, 4 one stator iron cores
Embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is done further detailed description
Its structure of a kind of motor stator is as shown in the figure, and it is made up of dead ring 1, stator winding 2, slot liner paper 3, stator core 4.Dead ring 1 adopt have thermal endurance, fold resistance, insulating material anti-aging and certain degree of hardness process, its physical dimension, notch are consistent with stator core, are anchored on two end faces of stator core 4; Dead ring 1 is not stretched out at slot liner paper 3 two ends in stator slot, and stator winding 2 does not have straightway at the groove port of export, and dead ring is as groove outlet insulation; Form rigid insulation; Be convenient to mechanization and roll off the production line and improve the operating efficiency that manual work is rolled off the production line, shorten the length of motor stator winding termination portion, practice thrift copper material 8-15%; Reduce the motor copper loss, reduce termination section leakage flux and leakage reactance, improve electric efficiency. be specially adapted to motor and generator unit stator in the electric rotating machine.
