Abstract
The utility model relates to a permanent magnet generator, comprising a casing, a stator and a shaft; wherein the shaft is sleeved with a sleeve, the outer wall of the sleeve is sleeved with a nonmagnetic material layer, 2n soft iron plates are evenly axially arranged at the outer wall of the nonmagnetic material layer equidistantly, the soft iron plate is provided with a thin nail which is fixedly connected with the sleeve after passing through the soft iron plates and the nonmagnetic material layer, and a permanent magnet is embedded in the inter-groove arranged between the two adjacent soft iron plates. Thereby the utility model has the advantages of simple and compact structure, and high efficiency and authenticity; due to leave out the excitation winding, the carbon brush and the slip-ring structure of the excitation type generator, thereby the utility model avoids the defects that the excitation winding is easy to be burned and broke, the carbon brush and the slip-ring are easy to be frayed, greatly increasing the authenticity; and at the same time, because leaving out the dynamic dissipating produced by the excitation winding which is used as the excitation power, the utility model is capable of reducing the fuel consumption per kilowatt about 10 percent, thereby lowering the generating cost, and reducing the pollution to the environment.
Description
Technical field
The utility model relates to a kind of generator, especially relates to a kind of permanent magnet generator.
Background technology
Traditional generator is generally the excitation-type generator, mostly is made of excitation winding, carbon brush, slip ring, stator etc.They generally exist problems such as volume is big, consumptive material is many, the rotor core wire casing takes up room greatly, its excitation winding is easily burnt, broken string.In addition, its carbon brush, slip ring are in long-time running, cause the phenomenon of mechanical loss to happen occasionally owing to rubbing between carbon brush, the slip ring, and the radio interference and the electric spark of carbon brush and slip ring friction meeting generation, therefore be not suitable for working under the higher environment of explosion risk degree.
Technology contents
Technical problems such as the utility model purpose provides a kind of permanent magnet generator, and is big, heavy to solve the existing volume of prior art excitation-type generator, and efficient is lower, be out of order easily.
The utility model mainly solves above-mentioned technical problem by following technical proposals: it comprises housing, stator, rotating shaft, be with sleeve in the described rotating shaft, on sleeve outer wall, be with layer of non-magnetic material, on the layer of non-magnetic material outer wall, axially be provided with even number soft iron piece uniformly and equidistantly, described soft iron piece is provided with thin nail, should thin nail pass soft iron piece, layer of non-magnetic material and sleeve and be fastenedly connected, be embedded with permanent magnet in the groove between between the described two adjacent soft iron pieces.
As preferably, be embedded with slot wedge between the described two adjacent soft iron pieces, this slot wedge is fixed on permanent magnet in the groove.
As preferably, described rotating shaft is provided with groove, and the protruding key of described sleeve can embed in its groove.
As preferably, described thin nail adopts stainless steel to make.
Therefore, the utlity model has compact conformation, simple, efficient height, characteristics such as reliability height.Owing to saved excitation winding, carbon brush, the slip ring structure of excitation-type generator, thereby avoided excitation winding easily to burn, break, fault such as carbon brush, slip ring are easy to wear, reliability greatly improves.And, because the unique abrading section of permanent magnet generator is a bearing, make complete machine safeguard easily, only need to add bearing oil and get final product.Simultaneously,, can reduce every kilowatt of fuel consumption 10%, therefore reduce cost of electricity-generating, and reduced pollution environment owing to saved the kinetic equation loss of excitation winding as field power supply.In addition, because the employing of permanent magnet rotor structure, thereby just not needing field power supply yet, generator is as long as can generate electricity once rotating.And allow the generator internal structure arrange very compactly, volume, weight greatly reduce, and have also eliminated radio interference and electric spark that the friction of carbon brush and slip ring produces simultaneously, therefore are particularly suitable for having the environment work down of explosion risk.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is the cutaway view of a kind of preferred implementation of the utility model;
Embodiment
Permanent magnet generator shown in Figure 1 is mainly formed by housing 1, stator 2 and by the p-m rotor that rotating shaft 10, sleeve 9, layer of non-magnetic material 6, soft iron piece 5, permanent magnet 4 etc. constitute.
In above-mentioned p-m rotor, jacket casing 9 is in rotating shaft 10, because this rotating shaft is provided with groove, so the protruding key 8 of sleeve can embed in its groove and makes sleeve 9 fixing.In order to prevent the permanent magnet leakage field, on sleeve outer wall, be with layer of non-magnetic material 6.On these layer of non-magnetic material 6 outer walls, axially be provided with the individual soft iron piece of forming by silicon steel sheet 5 of 2n (even number) uniformly and equidistantly, be installed on the thin nail 7 of some stainless steels on the soft iron piece, this is carefully followed closely 7 and passes soft iron piece 5, layer of non-magnetic material 6 backs and sleeve 9 and be connected by screw threads for fastening.After all soft iron pieces 5 and rotating shaft 10, sleeve 9 etc. are fixed together, just form between its adjacent two soft iron pieces certain width between groove, just can embed permanent magnet 4 in the groove so betwixt.
In order to make p-m rotor of the present utility model in rotation, its permanent magnet 4 can not get loose; Simultaneously, change permanent magnet 4 after also being convenient to.Between above-mentioned adjacent soft iron piece 5, promptly be embedded with slot wedge 3 on the opening part two of the groove opposition sidewalls therebetween, during installation, this slot wedge 3 can be pressed in permanent magnet 4 in the groove and make it fixing, when maintenance, pounds out slot wedge 3, just can take off permanent magnet 4.
Claims (4)
1. permanent magnet generator, comprise housing, stator, rotating shaft, it is characterized in that in described rotating shaft, being with sleeve, on sleeve outer wall, be with layer of non-magnetic material, on the layer of non-magnetic material outer wall, axially be provided with even number soft iron piece uniformly and equidistantly, described soft iron piece is provided with thin nail, and this thin nail passes soft iron piece, layer of non-magnetic material and sleeve and is fastenedly connected, and is embedded with permanent magnet in the groove between between the described two adjacent soft iron pieces.
2. permanent magnet generator according to claim 1 is characterized in that being embedded with slot wedge between described two adjacent soft iron pieces, and this slot wedge is fixed on permanent magnet in the groove.
3. permanent magnet generator according to claim 1 is characterized in that being provided with groove in described rotating shaft, and the protruding key of described sleeve can embed in its groove.
