Description
Technical field
The utility model relates to a kind of motor with permanent magnet rotor core, specifically a kind of single-phase RE permanent magnetic generator.
Background technology
Generator generally is made up of stator and rotor, and stator includes stator core, stator winding and support.Rare earth permanent-magnetic generator then is to be evenly equipped with watt shape magnetic pole that even number is made by rare earth permanent-magnetic material on rotor; Its stator winding then includes individual layer concentric type, single stacked, individual layer chained scheduling single layer winding, also has various ways such as two layer winding and positive chorded winding.The rare earth permanent-magnetic generator production technology of single layer winding is simple, and cost is lower.The problem that exists is that electrical quantity is relatively poor, and voltage-form distortion rate is more than 15%, and voltage regulation is more than ± 10%.Therefore its scope of application is general electrical appliance, as illumination, power etc.And the rare earth permanent-magnetic generator with two layer winding has then solved the voltage waveform problem better, and aberration rate can be less than 3%.But the problem that exists be two layer winding be that copper consumption is big with the line amount, it is big to take stator space, makes the generator volume increase, cost improves; Positive chorded winding also has the defective that can not make full use of the stator core space, so the power of this class generator unit volume is lower.
The utility model content
The purpose of this utility model just provides a kind of form realization low-voltage waveform aberration rate of single-layer stator winding and single-phase RE permanent magnetic generator of low-voltage regulation of adopting.
The utility model is to realize like this, single-phase RE permanent magnetic generator is made up of stator and rotor, stator includes stator core, stator winding and support, stator winding is a single layer winding, be evenly equipped with watt shape magnetic pole that even number is made by rare earth permanent-magnetic material on the rotor, be provided with an auxiliary winding in the middle of each utmost point main winding of stator winding, auxiliary winding is connected in series mutually with main winding.
Observe as can be known by oscilloscope, the rare earth permanent-magnetic generator of single-layer stator winding, the distortion of its output voltage waveforms mainly appears at crest and trough place.Its reason just is that the rotor of generator is after driving rotation through other engines, this single-layer stator winding construction is in generator output sinusoidal fundamental wave, can produce secondary, three inferior high-frequency harmonics, after these high-frequency harmonics and first-harmonic are synthetic, just make the bigger distortion of waveform generation of output voltage, correspondingly voltage regulation also just increases thereupon.The utility model is by relatively independent auxiliary winding of serial connection in the middle of every utmost point main winding, this just can suppress the generation of high order harmonic component well on the output voltage waveforms of stator winding, make the irregularity of wave form of output voltage less than 2%, voltage regulation is also corresponding to be reduced to less than ± 3%.
According to the single-phase RE permanent magnetic generator that aforesaid way is made, can make output voltage waveforms reach best sinusoidal waveform, and make generator efficiency reach maximum that voltage regulation is far superior to the voltage regulation of conventional electric generators ± 10% less than ± 3%.Under the condition of equal voltage regulation, promptly to compare with the generator of double-deck stator winding, the power output of this generator unit volume exceeds other motors more than 20%.The main feature of this utility model is exactly to have concentrated the advantage of traditional single layer winding and two kinds of generators of two layer winding, overcome effectively again simultaneously that two kinds of generators exist separately as the irregularity of wave form height, voltage regulation is big and stator slot utilizes defectives such as insufficient, that the unit volume power output is little.

Embodiment
As shown in Figure 1, 2, the stator winding of this single-phase RE permanent magnetic generator adopts single stacked winding.Fig. 1 is two pole type stator windings with two main windings, and it is the stator slot of 1-12 and 13-24 that two main windings have taken label respectively.Fig. 2 is the four pole type stator winding with four main windings.In the centre of each utmost point main winding 1, there are two wire casings (Fig. 1 is 6,7 two wire casings and 18,19 two wire casings, and Fig. 2 is as shown) to vacate, be used for the auxiliary winding 2 of coiling.The terminals of each main and auxiliary winding are connected in series successively by the mode of " main-auxilliary-auxilliary-main ", promptly constitute the stator winding of this single-phase RE permanent magnetic generator.The number of turn of each auxiliary winding 2 is no more than the number of turn in main winding 1 single groove.
Rotor structure of the present utility model is to adopt the rare earth permanent-magnetic material of radial magnetizing to make a watt shape magnetic pole 3, is distributed on the rotor 4 with even number.Fig. 3, Fig. 4 are the rotor structures of two kind of four magnetic pole form.Under the version of above-mentioned single-phase RE permanent magnetic generator stator winding, epitrochanterian magnetic pole is started at from two drift angles of watt shape magnetic pole 4, and its central angle β is preferably between 55-88 °.Fig. 5, Fig. 6 are the rotor structures of two kind of two magnetic pole form, and the central angle β of its watt shape magnetic pole 4 is preferably between 110-176 °.
Within above-mentioned magnetic pole β angle span, if determined after some angle betas of magnetic pole, then to the auxiliary umber of turn an of the best should be arranged, can make the generator output voltage waveform the most near or become sinusoidal waveform, promptly the elimination effect of high order harmonic component reaches best.If single groove number of turn of main winding is N, in above-mentioned β span, the number of turn of auxiliary winding 2 changes between 1-N, the value at the number of turn and the magnetic pole β angle relation that is inversely proportional to substantially.
