Problems solved by technology

[0002] Existing three-phase permanent magnet wind generators generally have multiple pairs of magnetic poles, and each pair of magnetic poles must have three windings, each winding must have a pair of wire slots, and there must be a certain amount of iron between the slots. The size of the core is used to ensure the needs of the winding and magnetic flux. It is difficult to reduce the size between the windings. The starting torque and starting wind speed are relatively large, and the running stability is poor.
At the same time, the volume is large, the consumables are many, and the cost is high

Embodiment Construction

[0022] As shown in Figure 1 and Figure 2.

[0023] The slotless building block breeze wind generator includes two main parts, the stator and the rotor.

[0024] In the middle of the stator is a central shaft 9 fixed on the machine base, and three groups of iron cores and coil windings are nested on the central shaft 9 in sequence, and each iron core and coil windings are provided at both ends. The insulating positioning partition 4, the coil 8 is radially wound in the I-shaped groove of the hollow I-shaped coil frame (not shown in the figure), and the two end faces of the coil frame are provided with radial radial grooves, which are stuck in the coil frame The iron core 7 in the radial radial groove is composed of two J-shaped silicon steel sheets. As Fig. 3, Fig. 4, described silicon steel sheet is J type, by silicon steel sheet outer side 71, silicon steel sheet middle part 72 and silicon steel sheet inner side 73, silicon steel sheet outer side 71 and silicon steel sheet i...

Abstract

The invention relates to a non-groove modular wind generator, which comprises stator and rotator. Wherein, the middle of stator is fixed on the middle axle of base; the middle axle is sheathed with one or several groups of iron cores and windings; the windings are radial winded on the hollow I-shaped winding support; the iron core clamped on the winding support is formed by two silicon steel plate in J-shape whose inner sides are connected and outer sides are alternated parallel; the rotator is formed by frame and several magnetic steels on the frame; the output of winding is axial outward along middle axle. The invention uses the theory of transformer based on former generator. Compared with traditional generator, it has simple structure and low noise, etc.

Description

technical field [0001] The invention relates to a generator, in particular to a slotless building block type breeze wind power generator for breeze wind power generation. Background technique [0002] Existing three-phase permanent magnet wind generators generally have multiple pairs of magnetic poles, and each pair of magnetic poles must have three windings, each winding must have a pair of wire slots, and there must be a certain amount of iron between the slots. The size of the core is used to ensure the needs of the winding and magnetic flux. The size between the windings is difficult to reduce, the starting torque and starting wind speed are relatively large, and the running stability is poor. At the same time, the volume is large, the consumables are many, and the cost is high. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a slotless building block type breeze wind power generator. ...
