Abstract
A magnet body structure for a motor rotor comprises groove punching plates, upper punching pieces, lower punching pieces and magnet blocks, wherein, a plurality of hole slots are formed on the groove punching plates, and notches are formed at the corresponding corners of the hole slots; the permanent magnets are inserted into the multi-layer laminated punching plate hole slots after the groove punching plates are laminated; the upper and the lower punching plates basically have the same shapes as the groove punching plates, are just hole slots without permanent magnets, and are respectively laminated at the outermost layers of the groove punching plates with permanent magnets so as to seal the permanent magnets in the punching plate layer of the rotor; after the punching plates are laminated, the notches at the corners of the punching plates are filled by cast aluminum; due to the above design, the metal punching plates surround the peripheries of the permanent magnets, so that the parts of the permanent magnets can be heated uniformly, thereby preventing the permanent magnet from easy crack caused by temperature difference; the permanent magnet can maintain original shape and efficacy under the action of magnetic force in case of breakage caused by collision; and accordingly, scraps are prevented from being thrown out, thereby protecting the motor from damage and exponentially prolonging the service life.
Description
Technical field
The present invention relates to field of motor manufacturing, relate in particular to the magnet structure of a kind of rotor of magneto.
Background technology
Rotor is the vital part of motor; Different according to rotating speed; On rotor, fixing the multipole permanent magnet of different numbers of poles respectively; The permanent magnet majority of magneto is to be inserted in the rotor surface with the glue adhesion or permanent magnet at present, and permanent magnet is hard crisp solid, easy of crack when collision is fallen in transit; Only between the 0.5-2 millimeter, the slit is more little in slit between rotor and the stator, and electric efficiency is high more.Motor is when high speed rotating, and the permanent magnet of adhesion usually can be thrown away by centrifugal force, perhaps because after running a period of time; Rotor heating, permanent magnet ectonexine excessive temperature differentials, and cracked gradually; As long as there is tiny chip to throw away, is attracted to motor is scrapped.This fault takes place at big motor at a high speed on one's body especially easily, and economic loss is also particularly serious.
In view of this, the inventor furthers investigate rotor, has solved puzzlement motor industry this hard nut to crack for many years finally, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of magnet structure of rotor, significantly improve the useful life of permanent magnet machine rotor, and failure rate significantly reduces.
To achieve these goals, technical scheme of the present invention is following:
A kind of magnet structure of rotor includes the groove punching, punching up and down, magnetic patch;
Have to be provided with several hole slot in the groove punching, have breach, after correspondence is superimposed, in the punching hole slot of multilayer build-up, insert permanent magnet in the corresponding corner of hole slot;
Punching and the shape basically identical of groove punching is arranged up and down only is a hole slot of not inserting permanent magnet, is superimposedly respectively inserting the outermost layer that the groove punching is arranged of permanent magnet, and the punching layer that is enclosed in permanent magnet rotor is inner.Be provided with like this, with the metal punching surrounded permanent magnet around, one is heated evenly each position of permanent magnet, difficultly causes ftractureing because of the temperature difference; Even two beat because of collision and to cause permanent magnet cracked, permanent magnet still can keep original shape and effect under magneticaction, be thrown out of the fault of damaging motor and chip will not occur;
After punching is superimposed, mend the corner indentation, there of punching full with cast aluminium.
Benefit of the present invention is that permanent magnet is closed in punching inside, and under the protection of metal level, the cracked probability of permanent magnet greatly reduces, even because of a variety of causes has had crackedly, also can under magneticaction, keep original shape and effect.The failure rate of rotor greatly reduces, and significantly improve useful life.

Description of reference numerals:
Punching about in the of 1,2 permanent magnets, 3 have the groove punching, 3-1 hole slot, 3-2 breach.
Embodiment
Through accompanying drawing and embodiment the present invention is done further to set forth in detail below.
Embodiment 1
A kind of magnet structure of 4 utmost point rotors such as Fig. 1 are to shown in Figure 3; 17 have groove punching 3 correspondences to be superimposed together; In 4 hole slot 3-1, insert four permanent magnets 2, in the superimposed punching 1 up and down of the outermost layer that groove punching 3 is arranged, be enclosed in internal rotor to permanent magnet 2 at last; Aluminium, polishing breach are melted in casting in all punching breach 3-2 again.
The basic structure of 6 utmost point rotors is identical with embodiment 1, difference be to use 6 hole slots are arranged groove punching 3 arranged, as shown in Figure 4, inserted 6 permanent magnets 2.
8 utmost point rotors or 10 utmost point motor rotor constructions are similar, used like Fig. 5, shown in Figure 6 groove punching 3 arranged.
The above is merely one embodiment of the present of invention, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection range of this case.
Claims (2)
1. the magnet structure of a rotor includes the groove punching, punching up and down, magnetic patch;
Have to be provided with several hole slot in the groove punching, have breach, after correspondence is superimposed, in the punching hole slot of multilayer build-up, insert permanent magnet in the corresponding corner of hole slot;
Punching and the shape basically identical of groove punching is arranged up and down only is a hole slot of not inserting permanent magnet, is superimposedly respectively inserting the outermost layer that the groove punching is arranged of permanent magnet, and the punching layer that is enclosed in permanent magnet rotor is inner.
2. the magnet structure of a kind of rotor according to claim 1 is characterized in that: after described punching is superimposed, mend the corner indentation, there of punching full with cast aluminium.
