Abstract
The utility model relates to a structure of a motor rotor body, in particular to the structure with permanent magnets arranged on the motor rotor body, which comprises the permanent magnets and the rotor body fixed on the motor shaft. A plurality of permanent magnets matched with the shapes of slot of the rotor body are inlaid in the axial direction on the outer ring of the rotor body. The utility model is simple and reasonable in structure. The performance of the motor is more stable and reliable, the precision of the motor is much higher, the maintenance, changing and assembling are convenient, and the service life of the motor is long. Accordingly, the usage cost is greatly lowered, and the requirements of users are satisfied to the maximum.
Description
Technical field
The utility model relates to a kind of structure of rotor body, especially relates to the structure that permanent magnet is installed on a kind of rotor body.
Background technology
At present, electromechanics trade is in developing magneto, because the application of p-m rotor, product is more energy-conservation, and volume reduces, but gummed mode or binding combination mode are generally all adopted in the installation of permanent magnet and rotor block, makes the stability of motor and the poor-performing of product.When adopting the gummed mode, the permanent magnet of rotor is come off from rotor block, motor is damaged; When adopting the binding combination mode, usually can make the motor performance variation, and complex process, electrical machinery life is short, and maintenance difficult can not satisfy present enterprise and pursue energy-conservation production demand.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure at the problem that prior art exists, and motor stabilizing is good, and motor precision height, function admirable are reliable, and cost is low, the structure of permanent magnet being installed on the rotor body of long service life.
The purpose of this utility model realizes by the following technical solutions:
The structure of permanent magnet is installed on the rotor body, comprises: permanent magnet, be fixed in the rotor block on the motor shaft, it is: some permanent magnets that are complementary with flute profile rotor block are inlayed on axially in the rotor block outer ring.
The flute profile of described rotor block be in dove-tail form groove or the ladder-type trough any one.
The utility model compared with prior art, because the form that adopts the groove shape of permanent magnet external shape and rotor block to be complementary, and be embedded on the rotor block, it is more firm to make that permanent magnet combines with rotor block, thoroughly solved and used the gummed mode in the prior art, the permanent magnet of rotor is easily come off from rotor block, motor is damaged; Use the binding combination mode, make the difficult problem of motor performance variation, complex process.The utility model is simple and reasonable for structure, and motor performance is more stable, more reliable, and motor precision height has made things convenient for maintenance, replacing and installation, and the motor long service life greatly reduces use cost, satisfies user's demand to greatest extent.

Fig. 1 is the utility model external structure schematic diagram;
Fig. 2 is the sectional structure schematic diagram of a kind of execution mode of the utility model;
Fig. 3 is the sectional structure schematic diagram of the another kind of execution mode of the utility model.
1 is motor shaft among the figure, and 2 is rotor block, and 3 is permanent magnet.
Embodiment
Below in conjunction with specific embodiment the utility model is further described in detail, but protection range of the present utility model is not limited by specific embodiment, is as the criterion with claims.In addition, with under the prerequisite of technical solutions of the utility model, any change or change that those of ordinary skills that the utility model is done realize easily all will fall within the claim scope of the present utility model.
The utility model external structure schematic diagram as shown in Figure 1 and Figure 2 and the sectional structure schematic diagram of a kind of execution mode of the utility model, comprise: permanent magnet 3, be fixed in the rotor block 2 on the motor shaft 1, when the flute profile of rotor block 2 outer rings is the dove-tail form groove, evenly be inlaid with some permanent magnets 3 that are complementary with dove-tail form groove shape rotor block 2 on rotor block 2 outer rings are axial.
Sectional structure schematic diagram as the another kind of execution mode of Fig. 1, the utility model external structure schematic diagram shown in Figure 3 and the utility model, comprise: permanent magnet 3, be fixed in the rotor block 2 on the motor shaft 1, when the flute profile of rotor block 2 outer rings is ladder-type trough, evenly be inlaid with some permanent magnets 3 that are complementary with ladder-type trough shape rotor block 2 on rotor block 2 outer rings are axial.
Claims (2)
1. the structure of permanent magnet is installed on the rotor body, comprise: permanent magnet (3), be fixed in the rotor block (2) on the motor shaft (1), it is characterized in that: some permanent magnets (3) that are complementary with flute profile rotor block (2) are inlayed on axially in rotor block (2) outer ring.
2. the structure of permanent magnet is installed on the rotor body according to claim 1, the flute profile that it is characterized in that described rotor block (2) be in dove-tail form groove or the ladder-type trough any one.
