Abstract
The utility model relates to a quadrature sine single layer winding. The utility model is characterized in that a stator is arranged with a main winding and a harmonic winding on an alternating-current generator whose stator slot number is 36 and pole number is 16. The main winding is a three-phase single layer symmetrical alternating current winding. Each coil has two types of turn numbers; the ratio of the two types turn numbers is 3:2. The coil pitch also has two types; the two types are respectively 1-4 and 1-3. The harmonic winding is a single-phase single layer equal turn equidistant winding with the pitch of 1-3, and is arranged in a slot with the main winding turn ratio of 2. The branch number an of each phase in the main winding =2; the three-phase Y is connected to output. The harmonic winding and the main winding form into the quadrature arrangement; the main winding outputs the sine voltage. The utility model has the advantages that: 1. the three-phase symmetrical winding realizes the single layer structure, which is labor-saving and material-saving; 2. the main winding has small phase belt harmonic and waveform deviation factor smaller than 3%; 3. the single-phase single layer harmonic winding and the single layer three-phase main winding are in quadrature and are not mutually interfered with good electromagnetic compatibility; 4. the stator slot has uniform filling rate and the motor has high efficiency.
Description
Technical field
The utility model relates to a kind of winding of generator, particularly a kind of orthogonal sinusoidal single layer winding.
Background technology
Every extremely every phase groove is counted the proper faction groove three-phase alternating current winding that molecule is an odd number, can't be designed to the positive chorded winding of the little individual layer of harmonic wave by traditional method for designing, assist the triple-frequency harmonics winding as the excitation source winding if increase in this motor, as not with the main winding quadrature, when working between then main and auxiliary winding interference is arranged mutually, and how conventional method fails to solve orthogonal design.
Summary of the invention
The purpose of this utility model designs a kind of orthogonal sinusoidal single layer winding exactly, and the intermediate frequency brushless generator that it makes output voltage height sine and the glitch-free main and auxiliary winding of quadrature all be necessary for single layer structure becomes possibility.
The utility model is achieved like this, in number of stator slots is 36 grooves, number of poles is on the alternating current generator of 16 utmost points, be furnished with the harmonious wave winding of main winding in the stator, main winding is a three-phase individual layer symmetrical alternating current winding, every circle has two kinds of numbers of turn, and two kinds of turn ratios are 3: 2, and coil span also has two kinds, be respectively 1-4 and 1-3, humorous wave winding is the equidistant windings of circle such as single-phase individual layer, and pitch is 1-3, and to be arranged in the main winding turn ratio be in 2 the groove, the every way a=2 that props up mutually of main winding, three-phase Y connection output, humorous wave winding and main winding form quadrature arrangement, main winding output sine voltage.
The utlity model has following advantage:＜1〉three-phase symmetric winding realized single layer structure, labor and material saving;＜2〉the main winding harmonic wave is little, and irregularity of wave form is less than 3%;＜3〉humorous wave winding of single-phase individual layer and individual layer three-phase main winding just do not disturb alternately, and Electro Magnetic Compatibility is good;＜4〉the stator slot filling rate is even, the electric efficiency height.
