Abstract
The invention discloses a motor rotor comprising a rotor core formed by superposing a plurality of rotor punching sheets, a rotating shaft and steel magnets. A plurality of steel magnet grooves and magnetic isolation grooves are arranged in the circumferential surface of the rotor core. The inner surfaces of the steel magnet grooves are coated with EP-138 adhesive. The steel magnets are pasted in the steel magnet grooves by EP-138 adhesive. A gap is left between the core and the steel magnets to enable the steel magnets to be pasted toward a fixed direction, and the steel magnets are sealed by adhesive tapes. According to the invention, as a gap is left between the core and the steel magnets to enable the steel magnets to be pasted toward a fixed direction, the yield rate of products is improved without affecting the characteristic values of motors.
Description
Technical field
The present invention relates to motor device field, be specifically related to a kind of rotor.
Background technology
Rotor resin impregnated adhesive tape device of the prior art generally comprises: rotor core, rotating shaft and magnet steel that multi-disc rotor punching is formed by stacking, on the periphery of rotor core, be provided with a plurality of magnet steel grooves and magnet isolation tank, described magnet steel is embedded in described magnet steel groove, described magnet steel seals by adhesive tape, and described adhesive tape is resin impregnated adhesive.The defect of this kind of structure is: owing to having certain margin of tolerance between rotor core sheet and magnet steel, if and this margin of tolerance manufacturer cannot hold or quality is stable not, magnet steel likely cannot pack rotor core sheet into so, or magnet steel coordinates tension to cause the destroyed situation of magnet steel overlay coating to occur with rotor core sheet.
Therefore, be necessary to provide a kind of rotor solving the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: a kind of rotor that improves product yield is provided
For achieving the above object, the technical solution used in the present invention is: a kind of rotor, comprise: the rotor core, rotating shaft and the magnet steel that are formed by multi-disc rotor punching superposition, on the periphery of described rotor core, be provided with several magnet steel grooves and magnet isolation tank, the inner surface of described magnet steel groove scribbles EP-138 glue, and described magnet steel is affixed in magnet steel groove by EP-138 gluing, leaves a space between described iron core and magnet steel, make magnet steel towards fixed party to pasting, described magnet steel seals by adhesive tape.
As the preferred technical scheme of one, described adhesive tape is resin impregnated adhesive.
Beneficial effect of the present invention is: the present invention, by leaving a space between iron core and magnet steel, makes magnet steel towards fixed party to pasting, thereby can improving product yield and do not affect motor characteristic value.
Brief description of the drawings
Fig. 1 is the structural representation of rotor in the present invention;
In Fig. 1: 1, rotor core, 2, rotating shaft, 3, magnet steel, 4, adhesive tape.
Embodiment
In order further to understand the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these are described is for further illustrating the features and advantages of the present invention, instead of limiting to the claimed invention.
As shown in Figure 1, a kind of rotor, comprise: the rotor core 1, rotating shaft 2 and the magnet steel 3 that are formed by multi-disc rotor punching superposition, described rotor core 1 is fixing by the rear aluminium casting of multi-disc rotor punching stack, on the periphery of described rotor core 1, be provided with several magnet steel grooves and magnet isolation tank, described magnet steel groove can according to the rotating speed of concrete rotor with and characteristic arrange, its number is generally 2 pairs, 4 equities, be even number, and identical to the magnet steel polarity on opposite.The inner surface of described magnet steel groove scribbles EP-138 glue, described magnet steel is affixed in magnet steel groove by EP-138 gluing, between described iron core and magnet steel, leave a space, make magnet steel towards fixed party to pasting, described magnet steel 3 seals by adhesive tape 4, in the present embodiment, described adhesive tape 4 is resin impregnated adhesive, it is preserved at low temperatures, add man-hour 80 degree drying room baking 5 hours, its thickness can reach the part of metal, with the fixing magnet steel of this adhesive tape, it is very small that the gap of adhesive tape and magnet steel can reach, gap than the fixing magnet steel of metal ring circle is much smaller, greatly reduce the friction between rotor and stator, higher to motor-field conducting effect conversion ratio, the shaping of can polishing after fixing with adhesive tape.
The present invention, by leaving a space between iron core and magnet steel, makes magnet steel towards fixed party to pasting, thereby can improving product yield and do not affect motor characteristic value.
It should be noted that, in this article, relational terms such as the first and second grades is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply and between these entities or operation, have the relation of any this reality or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby the process, method, article or the equipment that make to comprise a series of key elements not only comprise those key elements, but also comprise other key elements of clearly not listing, or be also included as the intrinsic key element of this process, method, article or equipment.The in the situation that of more restrictions not, the key element being limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises described key element and also have other identical element.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
