Description
Technical field
The utility model relates to technical field of motors, especially a kind of rotor structure of permagnetic synchronous motor.
Background technology
The same with traditional electric excitation synchronous motor, permagnetic synchronous motor is made up of stators and rotators two large divisions.The stator of permagnetic synchronous motor maintains static when motor runs, and structure is identical with electric excitation synchronous motor.Main building block comprises the parts such as the casing of armature winding, silicon steel sheet, end cap and secured core.The magnetic flux that permagnetic synchronous motor and electro-magnetic motor architectural difference are mainly manifested in magneto is provided by permanent magnet.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides that a kind of structure is simpler, cost is few, improves the rotor structure of the permagnetic synchronous motor of power of motor density and efficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of rotor structure of permagnetic synchronous motor, comprise rotor body, described rotor body comprises rotating shaft, pole shoe and permanent magnet, rotor body outer surface has first collar of magnetic material, described rotating shaft overcoat has lining, be dispersed with pole shoe and permanent magnet between described lining and first collar, described permanent magnet outer surface has second collar of nonmagnetic substance, and is provided with pad between second collar and permanent magnet outer surface.
Further, described lining is the lining of nonmagnetic substance.
Further, a permanent magnet is provided with between two pole shoes.
The beneficial effects of the utility model are: the utility model structure is simple, and raising can motor reliability, reduces cost, improves power density and the efficiency of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. pole shoe, 2. first collar, 3. second collar, 4. pad, 5. permanent magnet, 6. lining, 7. rotating shaft.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of rotor structure of permagnetic synchronous motor, comprise rotor body, rotor body comprises rotating shaft 7, pole shoe 1 and permanent magnet 5, rotor body outer surface has first collar 2 of magnetic material, rotating shaft 7 overcoat has lining 6, lining 6 is the lining of nonmagnetic substance, pole shoe 1 and permanent magnet 5 is dispersed with between lining 6 and first collar 2, a permanent magnet 5 is provided with between two pole shoes 1, permanent magnet 5 outer surface has second collar 3 of nonmagnetic substance, and is provided with pad 4 between second collar 3 and permanent magnet 5 outer surface.
High-speed cruising or diameter of the rotor proper larger time rotor surface need the centrifugal force that bears larger, and permanent magnet 5 only has certain tensile strength, is enclosed within rotor body outer surface with first collar 2, fixing pole shoe 1 and permanent magnet 5.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to right.
