Abstract
The utility model discloses a permanent magnet motor rotor structure. The structure comprises a rotor, an iron core, a plurality of magnets and a sheath. Balance mud plates are fixed to two ends of the iron core. An external diameter value of the balance mud plate is greater than the iron core. By using the permanent magnet motor rotor structure, the magnets which repel each other are pasted and fixed to the iron core through glue, and the magnets are fixed by the balance mud plates on the two ends of the iron core so that an extra fixing tool does not need to be added; production efficiency is increased and production cost is reduced.
Description
Technical field
The utility model belongs to Electric Manufacture technical field, particularly relates to a kind of rotor structure for permanent magnet motor.
Background technology
Permanent magnet machine rotor generally comprises rotating shaft, iron core and magnet, and iron core sleeve is located in rotating shaft.At present, the fixed form of magnet to be adopted rotor and the bonding mode of magnet, and magnet is pasted and fixed on iron core outer round surface by glue, and additional sheath is protected.
For example, notification number is CN203416062U, the applying date is the Chinese patent of 2013.08.02, a kind of rotor structure for permanent magnet motor is disclosed, magnet is pasted and is fixed on iron core outer round surface, and in the space forming between the axle head end face of the two axial ends of magnet sheath and iron core, stickup balance mud is realized the dynamic balance weight of rotor.
But, in glue bonding process, owing to having repulsive force between two permanent magnets, generally need frock to be fixed, waste time and energy like this.
Summary of the invention
For solving the deficiency existing in prior art, technical problem to be solved in the utility model is to provide a kind of convenient rotor structure for permanent magnet motor of installing, saving frock.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of rotor structure for permanent magnet motor, comprises rotor, iron core, polylith magnet and sheath, and described iron core two ends are fixed with respectively balance mud plate, and described balance mud plate external diameter value is greater than iron core.
Preferably, described balance mud sleeve-board is located in rotating shaft, and is connected with rotating shaft interference.
Preferably, the difference of described balance mud plate external diameter value and iron core external diameter value is 1mm.
Preferably, described sheath is stainless steel sleeve.
The beneficial effect of technical solutions of the utility model is:
A kind of rotor structure for permanent magnet motor, because its iron core two ends are fixed with respectively balance mud plate, described balance mud plate external diameter value is greater than iron core.Like this, the magnet mutually repelling is pasted while being fixed on iron core by glue, and magnet is fixed by the balance mud plate at iron core two ends, and not needing increases extra fixing tool, not only enhances productivity, and reduces production costs.
Brief description of the drawings
Fig. 1 is the structural representation of rotor structure for permanent magnet motor of the present utility model.
Fig. 2 is the sectional structure schematic diagram of rotor structure for permanent magnet motor of the present utility model.
Fig. 3 is the local structure for amplifying schematic diagram of Fig. 2.
Embodiment
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of rotor structure for permanent magnet motor of the present embodiment, comprises rotating shaft 1, iron core 5, two magnets 4, cylindrical circular sheath 2.Iron core 5 is sheathed in rotating shaft 1, and iron core 5 is connected with rotating shaft 1 interference.
In rotating shaft 1, closely the two ends near iron core 5 are also arranged with respectively circular balance mud plate 3, and same, balance mud plate 3 is connected with rotating shaft 1 interference.The external diameter value of balance mud plate 3 is greater than the external diameter value of iron core 5, and difference is 31.
Two magnets 4 that mutually repel are axially evenly pasted on the outer round surface of iron core 5 by glue along iron core 5, because the external diameter value of balance mud plate 3 is greater than the external diameter value of iron core 5, these two magnets 4 are fixing by the balance mud plate 3 at iron core 5 two ends, do not need to increase extra frock and are fixed.After glue curing, magnet 4 is fixed on the outer round surface of iron core 5 securely.In the present embodiment, difference 31 is 1mm.
Sheath 2 is evenly pasted and is fixed on the outer round surface of magnet 4 by glue.Sheath 2 adopts stainless steel sleeve, can strengthen protection effect.
In balance mud plate 3, paste balance mud and can realize the dynamic balance weight of the permanent magnetism electronics rotor of the present embodiment.
Above specific embodiment of the utility model is described.It will be appreciated that, the utility model is not limited to above-mentioned specific implementations, and those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
