Abstract
The utility model relates to a permanent magnetic A. C. synchronous electric power generator, comprising a casing, a stator assembly and a rotor assembly which are arranged in the casing. The utility model is characterized in that a rotor core formed by nestification of silicon-steel sheets is symmetrically provided with two axial trough-grooves with star-shaped longitudinal sections; magnetic steel made of permanent magnetic RE material is embedded in the axial through-grooves, which forms two poles of the rotor. Because the permanent magnetic rotor is composed of a small amount of ferromagnet and silicon-steel sheets, the utility model does not need exciting current, so that carbon brushes, slip-rings, exciting windings, and devices of commutators and current regulation are cancelled to enable the utility model to have the advantages of simpler construction and more reliable operation.
Description
The utility model relates to a kind of synchronous alternating-current generator, relates to a kind of permanent magnet AC synchronous generator that adopts rare earth permanent-magnetic material as permanent magnet specifically.
Present widely used power is 1KW～7.5KW, voltage 400V/230V, and frequency is 50HZ, and motor speed is that the synchronous alternating-current generator in 3000 rev/mins of scopes mostly is electric excitatory class, and input dc power on its rotor is to form magnetic pole.The synchronous alternating-current generator of the above-mentioned type is because of due to its structure, and ubiquity complex structure, easily the weak point of damaging.
The purpose of this utility model provides a kind of simple in structure with regard to being to overcome above-mentioned weak point of the prior art, and is reliable, and can improve the permanent magnet AC synchronous generator of its power.
The purpose of this utility model can adopt following measure to realize:
Permanent magnet AC synchronous generator of the present utility model comprises housing, is installed in field frame assembly and rotor assembly in the housing, is symmetrically arranged with two longitudinal sections and is on the rotor core that is formed by stacking by silicon steel sheet
The axial pass trough of shape, the magnet steel that is become by rare earth permanent-magnetic material making face is installed in this axial pass trough, constitutes two magnetic poles of rotor.
Be installed on the utility model rotor core each
The magnet steel of oblique crank Z in groove all is made up of three cuboid magnet steel; The mode of magnet steel by bonding is installed in and processes on the rotor core
Oblique crank Z is in groove.
Because the utility model is to constitute p-m rotor with a spot of kicker magnet with silicon steel sheet, does not need exciting curent, so cancelled carbon brush, slip ring, field winding and commutator and current regulating device on the electric exciting generator.Make structure of the present utility model more simple, move more reliable.In addition, because do not need input dc power to form magnetic pole on its rotor, the motor of the comparable prior art of its efficient improves about 7%.Moreover, because the air gap flux density of the utility model generator has surpassed the air gap flux density of the electric exciting generator of prior art, thereby has improved power output, the volume with the generator of power is reduced, this has also just saved raw material, has reduced production cost.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 rotor.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing):
Permanent magnet AC synchronous generator of the present utility model comprises housing (1), is installed in field frame assembly (2) and rotor assembly (3) in the housing, is symmetrically arranged with two longitudinal sections and is on the rotor core that is formed by stacking by silicon steel sheet (4)
