Abstract
The utility model discloses a kind of high speed durface mounted permanent magnet servo motor rotor structure, including rotating shaft, end plate one, magnet steel, rotor core and end plate two；The magnet steel is fixed on rotor core；The end plate one, rotor core and end plate two are set in rotating shaft；And end plate one and end plate two are separately fixed at the two ends of rotor core；The two ends of the magnet steel are in close contact with end plate one and end plate two；Bonding magnetic steel is on rotor core in the high speed durface mounted permanent magnet servo motor rotor structure, and magnet steel coordinates with rotor core neck, to reach resistance centrifugal force purpose, so as to avoid magnet steel from coming off, compared with prior art, reliability is improved, the high cost that steel bushing is brought, complex process defect are reduced again；Integrated operation is simple, and low cost has a wide range of application, practical.
Description
Technical field
The utility model is related to rotor structure technical field, specially a kind of high speed durface mounted permanent magnet servo motor rotor.
Background technology
At present, in some high speed durface mounted permanent magnet servomotors, rotor structure typically all uses two methods：Conventional
It is that magnet steel is Nian Jie with rotor core, outside uses to tie up without latitude glass fiber tape and twined；Special occasion uses magnet steel and rotor core
Bonding, outside replaces no latitude fiber band to be fastened with steel bushing.The former is the method that common electric machine is routinely used, and technique is simple,
Low cost, but fiber band aging is easily caused in high rotating speed or high temperature rise operating mode, the drawbacks of magnet steel comes off, reliability has limitation
Property.The latter typically uses in high rotating speed or ultrahigh rotating speed occasion, and structure is reliable, but complex process, high cost.
The content of the invention
The purpose of this utility model is to provide a kind of high speed durface mounted permanent magnet servo motor rotor structure, and it can be effective
Solve problem present in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of high speed durface mounted permanent magnet servomotor
Rotor structure, including rotating shaft, end plate one, magnet steel, rotor core and end plate two；The magnet steel is fixed on rotor core；It is described
End plate one, rotor core and end plate two are set in rotating shaft；And end plate one and end plate two are separately fixed at the two of rotor core
End；The two ends of the magnet steel are in close contact with end plate one and end plate two.
Further, the magnet steel is provided with several, and symmetrical expression annular is pasted onto the outer surface of rotor core.
Further, the magnet steel is provided with lug；The rotor core is provided with groove；The lug and matching grooves.
Compared with prior art, the beneficial effects of the utility model are：The high speed durface mounted permanent magnet servo motor rotor knot
Bonding magnetic steel is on rotor core in structure, and magnet steel coordinates with rotor core neck, to reach resistance centrifugal force purpose, so as to avoid
Magnet steel is come off, compared with prior art, improves reliability, and the high cost that steel bushing is brought, complex process defect are reduced again；Overall behaviour
Make simple, low cost has a wide range of application, practical；By lug and groove, make to keep away by coordinating between magnet steel and iron core
Exempt from the magnet steel that centrifugal force brings to come off；The unreliability of no latitude fiber band is improved, both advantages of fusion are real by mould
Existing, technique is simple, it is easy to accomplish.

In accompanying drawing：1. rotating shaft；2. end plate one；3. magnet steel；31. lug；4. rotor core；41. groove；5. end plate two.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1 ~ 4 are referred to, the utility model provides a kind of technical scheme：A kind of high speed durface mounted permanent magnet servo motor rotor
Structure, including rotating shaft 1, end plate 1, magnet steel 3, rotor core 4 and end plate 25；The magnet steel 3 is fixed on rotor core 4；Institute
End plate 1, rotor core 4 and end plate 25 is stated to be set in rotating shaft 1；And end plate 1 and end plate 25 are separately fixed at rotor
The two ends of iron core 4；The two ends of the magnet steel 3 are in close contact with end plate 1 and end plate 25.
Further, the magnet steel 3 is provided with several, and symmetrical expression annular is pasted onto the outer surface of rotor core 4.
Further, the magnet steel 3 is provided with lug 31；The rotor core 4 is provided with groove 41；The lug 31 and groove 41
Matching.
The utility model is in design：Magnet steel 3 is designed with lug 31, and rotor core 4 is provided with groove 41, makes both necks
Coordinate, change existing high speed surface-mount type servo motor rotor rotor one side poor reliability, magnet steel is easy to fall off, on the one hand
Though reliability is high, the drawbacks of the polarization of high cost；By the design of lug 31, groove 41, that improves its centrifugal direction can
By property, the aging unreliability because only leaning on fiber band to fix, or the cost rise that steel bushing fixing band is come, complex process are eliminated
Problem, rotor punching, magnetic steel die shaping, greatly improve operability and qualification rate, compared with prior art, the high speed table
Mounted permanent magnetic servo motor rotor structure does not increase raw material and process procedure, has saved production cost；Increase in structure design
Plus coordinate, for centrifugal action, substantially increase its reliability and usage range.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
