Abstract
The utility model relates to a reeling single and double novel winding for single phase and three phases. The equivalent pitch is shorter than Beta=2/3; the circuit rank is less; such winding has two pitches and two numbers of windings and the turn ratio is 2:1; the winding is formed into a single and double layers, and the tankful rate is the same. The winding can eliminate three harmonic with a low content of harmonic. The utility model has the advantages of simple manufacture; the working hours of winding and line dissemble of 33 percent can be reduced. The end is short; the insulation of trough layer is less; thereby the expensive copper wire and insulation material can be saved; the manufacturing cost can be reduced greatly. The waveform of the electrical machine of single and three phase which is made by such winding is good; asynchronous electric start capability and the adaptability are strong; the use is wide.
Description
Technical field
The utility model relates to list, the general AC Windings of three-phase, novel single, the general winding of three-phase of the single, double layer of especially a kind of lap winding type.
Background technology
Single, the general AC Windings of three-phase generally adopts the short distance winding of β=2/3, but this winding contains subharmonic such as abundant 5,7, and the generator voltage waveform is undesirable, and total harmonic distortion can not satisfy the needs of user to power supply wave shape greater than 5%.
Summary of the invention
The purpose of this utility model is improved the shortcoming of the short distance winding of β=2/3 exactly, makes in the voltage waveform of its winding output and not only eliminates 3 subharmonic, and weaken 5,7 inferior harmonic waves widely, thereby improve the sine of voltage waveform greatly.
The purpose of this utility model is realized by following technical scheme:
Novel single, the general AC Windings of three-phase of the single, double layer of a kind of lap winding type, its equivalent pitch is also littler than β=2/3, this winding of number of phases m=3, A only has 8 circles mutually, lacks 4 circles than tradition 12 circles, and this winding has two kinds of pitches, first kind of pitch is 13, promptly by 5-18,7-20,9-22 and 24-1,28-5,6 circles and second kind of pitch are 5, and promptly 11-16 and 30-35 are 2 circles totally 8 circle compositions.Wherein number of turn of the every circle of this 4 circle of 7-20,9-22 and 24-1,26-3 is 2 times of all the other 4 circle numbers of turn again.And all the other B, C and A 120 ° of electrical degrees of mutual deviation mutually, structure is analogized.The A of the utility model winding, B, C three-phase can K, Y, Δ connects and makes three phase electric machine, and also only A makes the monophase machine winding mutually.
The utility model has the advantages that significantly.
1) this winding is single, double layer structure, combines the advantage separately of single layer winding and two layer winding, and for example single layer winding can save layer insulation, and two layer winding short distance waveform is good.
2) the comprehensive effective pitch of this winding can be saved electromagnetic wire less than the pitch of β=2/3.
3) the every phase of this winding 8 circles only, and the individual layer groove accounts for 2/3 of total groove number, so the machining period saving reaches 33%, cost reduces greatly.
4) this winding list, three-phase can be general, its voltage waveform total harmonic distortion is good single, the general AC Windings of three-phase of a kind of electric property less than 5%.

Fig. 1 is the utility model structural representation;
Embodiment
An embodiment of the present utility model is shown in figure one, number of stator slots Z=36, number of poles 2P=2, number of phases m=3 is an example with A mutually, and winding has two kinds of pitches, first kind of pitch is 13, promptly by 5-18,7-20,9-22 and 24-1,28-5,6 circles and second kind of pitch are 5, and promptly 11-16 and 30-35 are 2 circles totally 8 circle compositions.Wherein number of turn of the every circle of this 4 circle of 7-20,9-22 and 24-1,26-3 is 2 times of all the other 4 circle numbers of turn again.And all the other B, C and A 120 ° of electrical degrees of mutual deviation mutually, structure is identical.Distribute mutually from figure one A, draw its winding coefficient computing formula easily and be .5 ° of K γ=° cos.60 °/12sin γ of 45 °+sinr15 of sin γ, wherein r=1,3,5,7...... thus as can be known the total harmonic distortion of its output voltage waveforms weaken greatly.The embodiment motor is surveyed its total harmonic distortion less than 5%.
