Expect radially fixed structure.
The technical solution adopted in the present invention has：A kind of radially fixed structure of magnetic suspension motor rotor magnetic material, including
Permanent magnet, mandrel, press strip screw and cross section are the press strip of fan shape, and it is rectangular-shaped installation that the mandrel is provided with cross section
Portion, four pieces of permanent magnets are respectively arranged on four side walls of installation portion, and are formed and the press strip shape between adjacent two permanent magnets
The installation cavity that shape is adapted, in the installation cavity, press strip screw is through press strip and is threaded on mandrel for press strip.
Further, four edges of the installation portion are provided with screwed hole, and press strip screw is provided with stepped hole.
The present invention has the advantages that：Simple structure of the present invention, it is easy for installation, save installation time and manpower
Cost, material saving is positioned by four press strips, limits the motion of magnetic material, it is ensured that the stability of the rotor after installation.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is sectional view of the present invention.
Specific embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the present invention discloses a kind of radially fixed structure of magnetic suspension motor rotor magnetic material, including
Permanent magnet 1, mandrel 2, press strip screw 4 and cross section are the press strip 3 of fan shape, and it is rectangular-shaped peace that mandrel 2 is provided with cross section
Dress portion 21, four pieces of permanent magnets 1 are respectively arranged on four side walls of installation portion 21, and are formed between adjacent two permanent magnets 1 and installed
Chamber 10, the installation cavity 10 is adapted with the shape of press strip 3, and in installation cavity 10, press strip screw 4 passes through press strip 3 and screw thread to press strip 3
It is connected on mandrel 2.
Screwed hole is provided with four edges of installation portion 21, press strip screw 4 is provided with stepped hole, and press strip screw 4 is passed through
Stepped hole is simultaneously threaded in screwed hole.The hexagonal fixing end that stepped hole is prevented from press strip screw 4 is exposed outside press strip 3.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as of the invention
Protection domain.
