Abstract
The utility model discloses a rotor core subassembly for servo motor has the main shaft, the rotor core who forms by the high velocity ram machine punching press has on the main shaft, this structure since rotor core through the punching press, impress, paste, towards magnetism technology to can promote production efficiency by a wide margin, reduce the disability rate, and can have apparent promotion to motor quality and wholeness.
Description
Technical field
This utility model relates to the core assembly of servomotor, especially relates to a kind of rotor core for servomotor and ties
Structure.
Background technology
The rotor core of servomotor typically uses attached magnetic magnetic sheet directly to paste, this structure paste time magnetic sheet frangible, cracking,
Operation easier is big, and naked eyes are difficult to, and affects performance and scrappage is high.It is thus desirable to a kind of behaviour relatively does simply,
Efficiently, again magnetic sheet is played protection and the excellent structure of overall performance.
Utility model content
The purpose of this utility model is to solve problem set forth above, it is provided that a kind of simple in construction, can play disk
Protection and the excellent a kind of rotor core structure for servomotor of overall performance.
The purpose of this utility model is achieved in that a kind of rotor core structure for servomotor, tool
There is main shaft, described main shaft has the rotor core being stamped to form by high velocity ram machine.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, described rotor ferrum
Magnetic sheet is attached on surface by core by resin.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, described rotor ferrum
The external diameter of core is 20mm to 200mm.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, described rotor ferrum
Core is stalloy.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, and described main shaft is
Bearing steel.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, and described resin is
Epoxy resin.
Further prioritization scheme is, above-mentioned a kind of rotor core structure for servomotor, and described magnetic sheet is
Neodymium iron boron.
Advantage of the present utility model: this utility model due to rotor core through punching press, be pressed into, paste, rush magnetic technique,
Such that it is able to significantly improving production efficiency, reduce scrappage, and motor quality and overall performance are obviously improved.
Accompanying drawing explanation
In order to make content of the present utility model be easier to be clearly understood, below according to specific embodiment and combine accompanying drawing, to this
Utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Reference: 1, main shaft, 2, rotor core, 3, resin, 4, magnetic sheet.
Detailed description of the invention:
As shown in Figure 1, a kind of rotor core structure for servomotor, there is main shaft 1, described main shaft 1 has by height
The rotor core 2 that speed punch press is stamped to form；Magnetic sheet 4 is attached on surface by described rotor core 2 by resin 3；Described rotor
The external diameter of iron core 2 is 20mm to 200mm；Described rotor core 2 is stalloy；Described main shaft 1 is bearing steel；Described resin
3 is epoxy resin；Described magnetic sheet 4 is neodymium iron boron.
Its work process is: described rotor core 2 uses high quality silicon steel disc, and axle, resin and magnetic sheet, through punching press, pressure
Enter, paste, rush magnetic and form.Rotor core 2 import high velocity ram machine, uses advanced person folded fourth of the twelve Earthly Branches technological requirement precision high.Perpendicularity
Ensure within 0.05mm-0.1mm.Axle uses import material, high accuracy processing, and hardness is high, is unlikely to deform.Resin 3 is
Import epoxide resin material, viscosity is strong, high temperature resistant, good stability.Magnetic sheet 4 uses import neodymium iron boron, and high temperature is difficult to demagnetization,
Stability is high.Rush overall performance after magnetic completes stable, excellent.
Particular embodiments described above, has been carried out the purpose of this utility model, technical scheme and beneficial effect the most in detail
Illustrate, be it should be understood that and the foregoing is only specific embodiment of the utility model, be not limited to this practicality new
Type, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, should be included in
Within protection domain of the present utility model.
