Abstract
The utility model discloses a permanent magnet synchronous gearless traction machine. The permanent magnet synchronous gearless traction machine comprises a shell, a stator arranged in the shell, a rotor rotationally arranged in the stator, and a traction wheel driven through a rotating shaft by the rotor. The permanent magnet synchronous gearless traction machine is characterized in that: the rotor comprises a magnetic yoke fixed on the rotating shaft, and a tile-shaped or square samarium cobalt permanent magnet fixed on the peripheral face of the magnetic yoke. Compared with the prior art, the permanent magnet synchronous gearless traction machine has the advantage that the manufacturing cost can be reduced.
Description
Technical field
The utility model relates to the application of a kind of novel permanent magnetic material on permanent-magnet synchnorous gearless dragging machine, belongs to the elevator technology field.
Background technology
Existing permanent-magnet synchnorous gearless dragging machine adopts neodymium iron boron (NdFeB) permanent magnetic material more; Quick rise along with the rare earth price; The price of neodymium iron boron (NdFeB) permanent magnetic material is also risen significantly, cause the price of traction machine also significantly to go up, thereby increased user's use cost.
Summary of the invention
The utility model purpose is to provide a kind of permanent-magnet synchnorous gearless dragging machine that manufacturing cost is reduced.
The utility model is to realize like this; Comprise casing, be arranged on stator in the casing, rotate the rotor that is arranged on the stator middle part, by the traction sheave of rotor through the rotating shaft drive, its special feature is that rotor comprises the yoke that is fixed in the rotating shaft, the tile that is fixed on the yoke side face or square shape SmCo (SmCo) permanent magnet.
Electromechanics trade can with permanent magnetic material aluminium nickel cobalt, ferrite permanent-magnet materials and rare earth permanent-magnetic material are arranged.Wherein, because of having excellent relatively performance, rare earth permanent-magnetic material is used widely.
In rare earth permanent-magnetic material, neodymium iron boron and SmCo are common two kinds.
The present invention seeks to realize like this: previous, because of the samarium cobalt rare earth permanent magnet body contains important strategic goods and materials--metallic cobalt,, only be used for military fields such as Aeronautics and Astronautics, navigation, weaponry so the samarium cobalt rare earth permanent magnet body costs an arm and a leg.Few people use it on the elevator traction machine.
Now, along with the demand of rare earth material increases and the adjustment of national industrial policies, the cost advantage of Nd-Fe-Bo permanent magnet material has not existed, far above the cost of samarium-cobalt material.Therefore, adopt tile samarium cobalt permanent magnet body, manufacturing cost just reduces significantly.
Compared with present technology the utility model has the advantage that manufacturing cost is reduced.
Description of drawings:
Fig. 1 is the structural representation of the utility model rotor;
Fig. 2 is the left view of Fig. 1.
Embodiment:
Combine accompanying drawing and embodiment that the utility model is done describes in further detail at present:
As shown in the figure; The utility model comprises casing, be arranged on stator in the casing, rotate the rotor that is arranged on the stator middle part, by the traction sheave of rotor through the rotating shaft drive, its special feature is that rotor comprises the yoke 2 that is fixed in the rotating shaft 5, the tile that is fixed on yoke 2 side faces or square shape or other shape SmCo (SmCo) permanent magnets 1.Permanent magnet 1 is close to the surface of yoke 2, and the N utmost point and S are extremely adjacent.
