Abstract

The utility model discloses a magnetic steel magnetism isolation pressing plate structure of a permanent magnet motor, comprising a magnetism isolation pressing plate (2) which is installed between two pieces of magnetic steel (1) and fixed on a rotor (4) by a screw (3); the cross section of the magnetism isolation pressing plate (2) takes on a U shape, and the bottom surface is a plane and provided with a screw hole used for installing the screw (3); the upper part of the U shape is provided with an inclined plane which is inclined outwards and used for closely pressing the magnetic steel (1); the magnetism isolation pressing plate (2) is made of a low-magnetic-conducting stainless steel sheet; and the bottom surface of the magnetism isolation pressing plate (2) is provided with six reinforcing ribs. The structure can be used for separating the magnetic steel and controlling the distance between the magnetic steel, and the magnetic steel can be closely pressed by the inclined plane, so that the reliability of the work of the magnetic steel is ensured. Furthermore, the low-magnetic-conducting stainless steel material is creatively selected as the material of the magnetism isolation pressing plate, so that the magnetic field of adjacent magnetic steel can be separated, the power density of the motor is effectively improved, and the cost is well controlled.

Description

The magneto magnet steel is every the magnetic pressure plate structure
Technical field
The utility model relates to the magneto technical field, relates to fixing the reaching of magneto magnet steel improved every magnetic, particularly relates to a kind of magneto magnet steel every the magnetic pressure plate structure.
Background technology
The installation of the permanent magnet magnet steel of magneto, fixing most important for the normal operation of motor especially is fixed in motor on the rotor for magnet steel.In order to prevent bad phenomenon such as magnet steel comes off, flies out in operation process, generally magnet steel is carried out fixing reliably.
Relatively the method for fixedly magnet steel commonly used has at present: directly use glue bonding; On the magnet steel punching install and fix with iron core on; On iron core, offer groove and with in the magnet steel embedded groove; Other various complicated mechanical fixed forms.Be not difficult to find out that from above several method usefulness glue is bonding the most simply, efficient and cost is low, be beneficial to batch process, but the reliability of this method magnet steel is not high, has certain potential safety hazard; Though other method structural reliability height, technology, complex structure are unfavorable for installing and cost control.
The utility model content
The purpose of this utility model is: provide a kind of magneto magnet steel every the magnetic pressure plate structure, it is simple in structure, safe and reliable, overcome directly with the glue not high problem of reliability that magnet steel brought that is adhesively fixed, can on the basis that strictness is controlled cost, can improve the reliability of motor rotation effectively, can separate and compress magnet steel well, play good simultaneously every the magnetic effect.
A kind of technical scheme of the present utility model is: a kind of magneto magnet steel is every the magnetic pressure plate structure, and it comprises every the magnetic pressure plate, describedly be installed between the magnet steel every the magnetic pressure plate, and by screw on rotor; Be like the U type every magnetic pressure plate cross section, the bottom surface is provided with the screwed hole that is used for mounting screw, is provided with the inclined plane that outward-dipping being used to compresses magnet steel every the both sides that are positioned at U type top of magnetic pressure plate.
Described is the plane every magnetic pressure plate bottom surface.
The described low magnetic conduction of making for low magnetic stainless steel thin plate every the magnetic pressure plate is every the magnetic pressure plate.
Describedly be provided with reinforcement every magnetic pressure plate bottom surface.Can be provided with six reinforcements as preferred version.
The utility model has the advantages that:
1, magneto magnet steel of the present utility model relates to the improvement to magneto magnet steel fixed structure every the magnetic pressure plate structure, overcomes directly with the glue not high problem of reliability that magnet steel brought that is adhesively fixed.By setting up every the magnetic pressure plate, both can separate magnet steel, the distance between the control magnet steel can also compress magnet steel by the inclined plane, can improve the reliability of motor rotation on the basis that strictness is controlled cost effectively.
2, magneto magnet steel of the present utility model in the selection of material, has been selected low magnetic stainless steel material every the magnetic pressure plate structure innovatively, the magnetic field between can the space between adjacent magnet steel, thus promote the power density of motor effectively.
3, magneto magnet steel of the present utility model is every the magnetic pressure plate structure, and the setting of its bottom surface reinforcement has strengthened the rigidity every the magnetic pressure plate well, guarantees the reliability of itself.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is that the magneto magnet steel is every the planform of magnetic pressure plate structure and the schematic diagram that installs and fixes;
Fig. 2 is the vertical view of Fig. 1.
Wherein: 1 magnet steel; 2 every the magnetic pressure plate; 3 screws; 4 rotors.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of magneto magnet steel is every the magnetic pressure plate structure, and it comprises and being installed between the magnet steel 1 every magnetic pressure plate 2 every magnetic pressure plate 2, and is fixed on the rotor 4 by two screws 3.
Be like the U type every magnetic pressure plate 2 cross sections, the bottom surface is the plane, and the bottom surface is provided with the screwed hole that is used for mounting screw 3.Have certain clearance between bottom surface and the rotor 4.
Be used to separate magnet steel 1 every magnetic pressure plate 2 bottoms, control the interval between the adjacent magnet steel 1; Every outward-dipping formation inclined plane, both sides, magnetic pressure plate top, can compress magnet steel 1 well.Be provided with six reinforcements every magnetic pressure plate 2 bottom surfaces, can promote its rigidity effectively, guarantee maintainability.
Make for low magnetic stainless steel thin plate every magnetic pressure plate 2.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection range of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
