Abstract
The utility model relates to a permanent magnet generator with simple structure and cheap price. The permanent magnet generator mainly consists of a housing, permanent magnets, a turntable, a carbon brush, an end plate and screws, wherein the turntable comprises a coil, a reverser and a shaft, a plurality of permanent magnets are connected in the housing, the permanent magnets with polarities N, S are staggered, the oval coil of the turntable is cast into an oval disc shape by using epoxy resins, the center of a disc is connected with the shaft with the reverser, the shaft of the turntable is inserted in the hole of the end plate with the carbon brush so as to be arranged in the housing together with the end plate, and the reverser is in electric contact with the carbon brush. By adopting the turntable for replacing a rotor of the traditional permanent magnet generator, the permanent magnet generator has the advantages of convenient manufacturing, low cost and light weight.
Description
Technical field
The utility model relates to a kind of simple in structure, permanent magnet generator that cost is low.
Background technology
Present existing permanent magnet generator mainly is made up of permanent magnet, rotor, shell, carbon brush etc., its rotor with silicon steel sheet process iron core, line surrounds and forms on the iron core, exist to make complicated, the deficiency that cost is high.
Summary of the invention
Exist manufacturing complicated in order to overcome existing rotor of permanent-magnetic power generator, the deficiency that cost is high, the purpose of the utility model provide a kind of simple in structure, inexpensive permanent magnet generator.
The utility model technical scheme that is adopted of dealing with problems is: mainly be made up of shell, permanent magnet, rotating disk, carbon brush, end plate, screw; Rotating disk comprises coil, axle, commutator; Connect the polylith permanent magnet in the enclosure and be arranged in circle, the permanent magnet of N, S polarity is interconnected, and the oblate coil of rotating disk becomes oblate dish type with poured with epoxy resin; Connect the axle that has commutator in disc centre; Turntable shaft inserts and has in the end plate bore of carbon brush, cased together connection, and commutator and carbon brush electrically contact.When rotating disk rotated, the winding wire cutting permanent magnet magnetic line of force induced the electromotive force generating on the rotating disk.Substitute the rotor of conventional electric generators because of this permanent magnet generator adopts rotating disk, rotating disk does not have core structure, thereby makes more convenient, in light weight, yet low simple in structure, the inexpensive purpose of the utility model that reaches of cost.
The beneficial effect of the utility model is, and is simple in structure, inexpensive.Also because of there not being iron core in light weight.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Figure is the sectional structure chart of the utility model embodiment.
1 shell, 2. permanent magnets, 3. rotating disk 3-1. coil 3-2. commutator 3-3. axles, 4 carbon brush, 5. end plates, 6. screws among the figure
Embodiment
In the embodiment shown in the figure, evenly staggered bonding polylith N, S utmost point permanent magnet 2 are arranged in circle on the end plate in shell 1, and permanent magnet 2 forms N, S utmost point flux loop with end plate 5.The oblate coil 3-1 of rotating disk 3 becomes oblate dish with poured with epoxy resin, disc centre connect one have a commutator 3-2 axle 3-3, commutator 3-2 is electrically connected with coil 3-1.It is interior with screw 6 connections that axle 3-3 inserts the shell 1 of packing into together in the hole that has carbon brush 4 end plates 5 on the rotating disk 3, and the position of assembling back rotating disk 3 is in the middle of the air gap between permanent magnet 2 and the end plate 5, and the commutator 3-2 that connects on the end plate 5 on a carbon brush 4 and the 3-3 electrically contacts.When rotating disk 3 rotations, the magnetic line of force of coil 3-1 upper conductor cutting permanent magnet 2 induces electromotive force through commutator 3-2 and carbon brush 4 power supplies.
