Problems solved by technology

The problem is that the electrical parameters are poor, the voltage waveform distortion rate is above 15%, and the voltage adjustment rate is above ±10%.
However, the existing problem is that the double-layer winding uses a large amount of wire, that is, a large amount of copper, and occupies a large space in the stator, which increases the volume of the generator and increases the cost; the sinusoidal winding also has the defect of not being able to fully utilize the space of the stator core, so this type of The power per unit volume of the generator is low

Embodiment Construction

[0011] Such as figure 1 , 2 As shown, the stator winding of the single-phase rare earth permanent magnet generator adopts a structure in which a single-layer laminated winding (main winding) is connected in series with an auxiliary winding. figure 1 It is a two-pole stator winding with two main windings, and the two main windings occupy the stator slots 1-12 and 13-24 respectively. figure 2 It is a four-pole stator winding with four main windings. In the middle of each pole main winding 1, there are two slots ( figure 1 There are two wire slots 6 and 7 and two wire slots 18 and 19. figure 2 As shown in the figure) is vacant for winding the auxiliary winding 2. The terminals of the main and auxiliary windings are sequentially connected in series in the manner of "main-auxiliary-auxiliary-main" to constitute the stator winding of the single-phase rare earth permanent magnet generator. The number of turns of each auxiliary winding 2 does not exceed the number of turns in a...

Abstract

The present invention is one RE permanent magnetic generator with permanent magnet rotor and consists of stator and rotor. The stator includes iron core, single-layer winding and seat; and the rotor has even number of tile-shaped magnet poles of RE permanent magnetic material distributed homogeneously. The stator winding has several subsidiary windings, each of which is connected serially to the main winding of each pole. The generator of the present invention has the advantages of both single-layer winding and double-layer winding and has output voltage waveform deformation rate lower than 2 % and voltage regulating rate lower than 3 %.

Description

technical field [0001] The invention relates to a motor with a permanent magnet rotor core, in particular to a single-phase rare earth permanent magnet generator. Background technique [0002] The generator is generally composed of a stator and a rotor, and the stator includes a stator core, a stator winding and a frame. The rare earth permanent magnet generator is evenly distributed on the rotor with an even number of tile-shaped magnetic poles made of rare earth permanent magnet materials; its stator windings include single-layer concentric, single-layer stacked, and single-layer chain. Winding, there are many forms such as double-layer winding and sinusoidal winding. The production process of the rare earth permanent magnet generator with single-layer winding is simple and the cost is low. The existing problems are that the electrical parameters are poor, the voltage waveform distortion rate is above 15%, and the voltage adjustment rate is above ±10%. Therefore, its sc...
