Abstract
Disclosed is a permanent magnetism motor rotor structure, comprising a rotating shaft, two baffle plates, a permanent magnet, and rotor punching sheets, wherein one of the two baffle plates is provided with a small hole and an annular groove; the rotor punching sheets are laminated together to form a hollow and circular column-shaped rotor iron core; a magnet groove is arranged between the internal surface and the external surface of the rotor iron core; the permanent magnet is embedded inside the magnet groove; two ends of the rotor iron core are each fixedly provided with a baffle plate respectively; and the rotating shaft passes through the rotor iron core and the central section of the baffles and is fixed. The permanent magnetism motor rotor structure features simple structure, excellent manufacturability, low making cost, and the like.
Description
Technical field
The utility model relates to generator or motor, specifically is a kind of rotor structure for permanent magnet motor.
Background technology
As the major part that magneto magnetic field is set up, the performance of permanent magnet is very big to the influence of motor properties, in order to guarantee the operate as normal of magneto, needs effective protection and secure fixation to the permanent magnet in the rotor core.
Magneto for built-in magnetic structure; After permanent magnet embedded in the magnet slot unshakable in one's determination, two ends fitted tightly with baffle plate usually, can make permanent magnet at axial restraint on the one hand; Avoid permanent magnet to be exposed in the air on the other hand, receive the erosion of airborne oxious component.Simultaneously, in order to make permanent magnet secure fixation in iron core, best bet is under the environment of vacuum pressure, to flood or inculcate adhesive.
Because in order effectively to protect permanent magnet, permanent magnet is positioned at magnet slot, it is very close to each other that two ends have baffle plate to fit tightly, and adhesive can't get into rotor core inside like this, reaches and fill gap, the purpose of secure fixation permanent magnet.
Summary of the invention
The utility model technical problem to be solved is; Not enough to prior art; A kind of rotor structure for permanent magnet motor is provided, solve current rotor structure for permanent magnet motor can't realize adopting vacuum pressure impregnation or or the method for inculcating adhesive make the problem of permanent magnet secure fixation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of rotor structure for permanent magnet motor comprises rotating shaft, two baffle plates, permanent magnet and rotor punchings; Have aperture and cannelure on arbitrary of two baffle plates; Aperture is on cannelure, and rotor punching overlaps together the rotor core of forming the hollow cylinder shape, is provided with magnet slot between the inner surface of rotor core and the outer surface; Permanent magnet embeds in the magnet slot; The rotor core two ends are fixed with a baffle plate respectively, and rotating shaft is passed the middle part of rotor core and baffle plate and is fixed, and the space between permanent magnet and the magnet slot, aperture, cannelure constitute the loop.
The loop can let fluid flow.
In the space between permanent magnet and the magnet slot slot wedge is arranged, be used for regulating pore size.
The utility model can not only effectively protect permanent magnet, can also guarantee that dipping lacquer is abundant, solidifies the back and forms paint film; Thereby make the permanent magnet secure fixation, baffle plate can be used for the rotor core axial restraint simultaneously, and the utility model also has simple in structure; Good manufacturability, characteristics such as low cost of manufacture.
Description of drawings
Fig. 1 be the rotor of the utility model embodiment motor along motor shaft to cut-away illustration;
Fig. 2 is the three-dimensional model diagram of the baffle plate of the utility model band aperture and cannelure.
Wherein:
1: rotating shaft; 2: slot wedge; 3: the baffle plate of band aperture and cannelure; 4: permanent magnet: 5: rotor punching; 6: backboard; 7: aperture and cannelure; 8: aperture; 9: cannelure.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
Accompanying drawing 1 and accompanying drawing 2 are respectively the rotor of the utility model embodiment motor along the three-dimensional structure sketch map of motor shaft to the baffle plate of cut-away illustration and band aperture and cannelure.Shown in accompanying drawing 1, backboard 6 and rotor punching 5 embed permanent magnet 4 after laminating in the rotating shaft 1, regulate the gap with slot wedge, at last with baffle plate 3 axial restraints of being with aperture and cannelure.To assemble the p-m rotor of accomplishing again and under the environment of vacuum pressure, flood or pour into adhesive, it is inner that adhesive gets into rotor core from the aperture of baffle plate 3 and cannelure, fills the gap of permanent magnet and magnet slot, and curing is in aggregates under suitable temperature conditions.
Permanent magnet is embedded in the rotor core, and the size of suitable formation paint film is adjusted in formed gap between the magnet slot on itself and the rotor punching with slot wedge; The length overall of assembling back permanent magnet is slightly shorter than the length overall of iron core; Permanent magnet is fixed with end plate after being embedded in rotor core; One end end plate and rotor core surface fit tightly; Other end end plate have in the position that slot wedge is installed be uniformly distributed with advance to coat with lacquer aperture; There is cannelure to be communicated with between each aperture, is placed with loose institutional framework, can after dipping lacquer solidifies, can fill up the cushion block in the gap between baffle plate and permanent magnet in permanent magnet surfaces.
Claims (2)
1. a rotor structure for permanent magnet motor comprises rotating shaft, two baffle plates, permanent magnet and rotor punchings, it is characterized in that; Have aperture and cannelure on arbitrary of two baffle plates; Aperture is on cannelure, and rotor punching overlaps together the rotor core of forming the hollow cylinder shape, is provided with magnet slot between the inner surface of rotor core and the outer surface; Permanent magnet embeds in the magnet slot; The rotor core two ends are fixed with a baffle plate respectively, and rotating shaft is passed the middle part of rotor core and baffle plate and is fixed, and the space between permanent magnet and the magnet slot, aperture, cannelure constitute the loop.
2. rotor structure for permanent magnet motor according to claim 1 is characterized in that, in the space between permanent magnet and the magnet slot slot wedge is arranged.
