Abstract
The utility model relates to a rotor body structure of a motor, in particular to the rotor body structure which can provide motor stability. The rotor body structure comprises magnetizers, permanent magnets and a rotor body arranged on a motor shaft, and is characterized in that the plurality of permanent magnets and a plurality of magnetizers are sequentially arranged on an outer ring of the rotor body in the axial direction and fixed on the rotor body through fixing pieces. Compared with the prior art, the rotor body structure of the motor adopts the magnetizers to press on the permanent magnets so that the permanent magnets and the rotor body to be combined more tightly, the problem of the structure of the weak permanent magnets in the prior art is thoroughly solved, the traditional way that the permanent magnets are apt to fall off from the rotor body to lead the motor to be damaged is changed, and the phenomena of demagnetization of the permanent magnets are reduced. The rotor body structure of the motor is simple and reasonable in structure, performance of the motor is more stable and reliable, efficiency of the motor is improved, service life of the motor is prolonged, use cost is greatly reduced, and updating and upgrading of the rotor body structure of the motor is achieved.
Description
Technical field
[0001] the utility model relates to a kind of structure of rotor body, relates in particular to a kind of rotor body structure that motor stabilizing property can be provided.
Background technology
At present, electromechanics trade is more extensive in the motor application of developing rotor banding magnetic, and the motor product of rotor banding magnetic makes product more energy-conservation owing to carry magnetic, and torque is adaption demand more, and volume reduces.But, motor can not be worked under complicated situation because the overladen appearance of torque and load makes permanent magnet produce demagnetization.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure to the problem that prior art exists, and motor stabilizing property is good, and the motor precision is high, and function admirable is reliable, and cost is low, reduces and does not demagnetize the motor rotor construction of long service life.
The novel purpose of this use is to realize through following technical scheme:
A kind of rotor body structure comprises: the rotor block on magnetic conductor, permanent magnet and the motor shaft, and it is to be provided with some permanent magnets and magnetic conductor successively on the rotor block outer ring is axially, and described permanent magnet and magnetic conductor are fixed on the rotor block through fixture.
Described permanent magnet is replaced by the excitation body.
The cross sectional shape of described rotor block is polygon or prismatic.
The utility model is compared with prior art owing to adopted magnetic conductor to be pressed on the permanent magnet; It is more firm to make that permanent magnet combines with rotor block; Thoroughly solved the unstable structure of permanent magnet in the prior art; Changed permanent magnet and be prone to come off from rotor block, the traditional approach that motor is damaged has reduced the phenomenon that permanent magnet demagnetizes.The utility model is simple and reasonable for structure, and motor performance is more stable, more reliable, and electric efficiency improves, and makes the motor longer service life, greatly reduces use cost, makes the rotor body structure realize further regenerating.
Description of drawings
Fig. 1 is the cross-sectional view of a kind of execution mode of the utility model;
Fig. 2 is the perspective view of the utility model.
Among the figure: magnetic conductor 1, permanent magnet 2, rotor block 3, motor shaft 4, fixture 5.
Embodiment
Below in conjunction with specific embodiment the utility model is further specified; But the protection range of the utility model is not limited by concrete embodiment; Be as the criterion with claims; In addition, with under the prerequisite of the utility model technical scheme, any change or change that those of ordinary skills that the utility model is made realize easily can both fall within the claim scope of the utility model.
Like the cross-sectional view of Fig. 1, a kind of execution mode of the utility model shown in Figure 2 and the perspective view of the utility model.Comprise: the cross sectional shape on magnetic conductor 1, permanent magnet 2 and the motor shaft 4 is hexagonal rotor block 3; Be provided with some permanent magnets 2 and magnetic conductor 1 on the axial seamed edge in these rotor block 3 outer rings successively, described permanent magnet 2 is fixed on the rotor block 3 through bolt 5 with magnetic conductor 1.
Described permanent magnet 2 is replaced by the excitation body.Other is with embodiment 1.
Claims (3)
1. rotor body structure; Comprise: the rotor block (3) on magnetic conductor (1), permanent magnet (2) and the motor shaft (4); It is characterized in that: be provided with some permanent magnets (2) and magnetic conductor (1) successively on rotor block (3) outer ring is axial, described permanent magnet (2) and magnetic conductor (1) are fixed on the rotor block (3) through fixture (5).
2. a kind of rotor body structure according to claim 1 is characterized in that described permanent magnet (2) is replaced by the excitation body.
