Abstract
The utility model provides an adopt tombarthite permanent magnet material as synchronous permanent magnet generator of rotor magnetic pole. The permanent magnet motor comprises a stator, a stator winding, a permanent magnet rotor, a fan and a shell. The permanent magnet generator rotor is mainly characterized in that a silicon steel sheet laminated core, a rotor winding and accessories thereof are not arranged on the generator rotor, rare earth permanent magnet blocks are used as magnetic poles, and the size, the number and the positions of the magnetic poles determined according to the capacity, the rotating speed and the characteristics of a hydro-magnetic material of the generator are directly fastened on the cylindrical surface of a rotor core to form the permanent magnet rotor.
Description
The utility model belongs to the industrial frequency synchronous generator, is to adopt rare earth permanent-magnetic material to make, and is applicable to internal combustion engine, the hydraulic turbine, wind energy conversion system ... Deng the composition generating set.
At present, most practical generator amatures are to produce magnetic with the electromagnetism winding to make, and complex process, volume weight is big, energy consumption is high.The generator of the p-m rotor that existing before this employing rare earth hydromagnetic material is made, as Chinese patent 92204162.8 promptly is an example, members such as its field winding of no use, carbon brush, thereby weight reduction, cut down the consumption of energy, but be difficult for heat radiation in overall structure, the machine because of it adopts, make rare earth permanent-magnetic material when working long hours, may influence the stability in magnetic field because of temperature rise, strengthen cost, cause to apply to be restricted.
The purpose of this utility model is being improved the structural design of generator amature, adopts the neodymium iron boron of sintering, provides a kind of stable performance, with low cost, generator rational in infrastructure, easy to maintenance.
P-m rotor of the present utility model adopts the cylindrical rotor core, links rotating shaft, and the fastening magnetic pole of making of the rare earth permanent magnet piece of sector crosssection of going up of outer surface is made.Its generating mechanism is consistent with conventional electric generators, and promptly when rotor rotated in stator, the magnetic line of force of rare earth permanent-magnetic material magnetic pole on the stator coil cutting rotor produced induced electromotive force thereby make in the stator coil, send electric energy in other words.
The utility model is formed structure accompanying drawing branch by rotor, stator, stator coil, shell, fan and is described as follows:
As (1) among accompanying drawing 1, the figure is generator casing, by bearing (7) rotating shaft (5) is supported, rotating shaft (5) connecting cylindrical rotor core (4), at surperficial fastening the magnetic pole of rare-earth permanent magnet (3) of rotor core (4), one end of axle (5) is equipped with a fan rotating vane (6) and rotates with axle (5), cause the air flows in the generator, to get rid of the heat that produces in the generator, keep suitable temperature levels in the generator.On shell (1), be connected with stator core and embed the interior winding (2) of iron core slot, when rotor sways, promptly send electric energy at stator winding.
Principal character of the present utility model is the formation of generator amature, as shown in Figure 2: rotor is made up of three parts, rotating shaft (5) is connected with rotor core (4), part (4) can be two compositions with (5), also can be an integral body, on the face of cylinder of rotor core (4) by the fastening magnetic pole (3) of going up requirement of number of poles requirement, magnetic pole (3) is made by rare earth permanent-magnetic material, axial cross section is fan-shaped, magnetic pole covering of the fan angle and length, the difference of generator capacity, rotating speed, magnetic material performance is looked in thickness and installation site, determines in generator designs.
The utility model and internal combustion engine, the hydraulic turbine, wind energy conversion system ... prime movers is formed generating set, be specially adapted to not have electricity, the usefulness of the middle-size and small-size power supply of power-shortage area is especially with the combination of gasoline engine, can standby at any time startup, operation, out of service, for the user provides single-phase or three phase supply.
Claims (2)
1. the utility model magneto alternator, belong to the industrial frequency synchronous generator, be primarily characterized in that generator casing [1] supports rotating shaft [5] by bearing [7], rotating shaft [5] is connecting cylindrical rotor core [4], surperficial fastening the magnetic pole of rare-earth permanent magnet [3] at rotor core [4], on shell [1], be connected with stator core and embed the interior winding [2] of iron core slot.
2. magneto alternator according to claim 1 is characterized in that epitrochanterian magnetic pole makes with the rare earth permanent-magnetic material piece, and the geometry of magnetic pole is axial sector crosssection.
