Abstract
The utility model relates to an asynchronous motor squirrel cage. The both ends of the cage strips of the squirrel cage are provided with a comb-shaped notch, the improvement of the structure of the asynchronous motor squirrel cage reduces the heating pressure of the end of rotor cage strips during starting, running and stopping cooling of the motor, and therefore, the phenomenon of the breaking of the cage strips is reduced and the copper material consumption is saved.
Description
The utility model relates to a kind of rotor of cage induction motor, particularly the asynchronous machine mouse cage.
Common cage induction motor cage-shaped structure all adopts whole copper bar and end ring welding, the bending rigidity of cage bar and axial extensional rigidity are all bigger, and be that displacement load is caused by the thermal stress that rising-heat contracting-cold causes, so rigidity is big more, caused stress is also big more, so phenomenon of rupture often takes place in the motor use cage bar of common asynchronous moter mouse cage.Chinese patent CN2101340U discloses a kind of shallow/deep groove type cage rotor bar-broken preventing system, and it fractures cage bar end integral body and bends back and end ring welding fabrication, and this kind structural manufacturing process complexity, bending rigidity be obviously minimizing not, and copper material consumption is big.
The purpose of this utility model is to provide a kind of and reduces mouse cage cage bar phenomenon of rupture and save the asynchronous machine mouse cage that copper material consumes.
The purpose of this utility model realizes finishing as follows: the asynchronous machine mouse cage, and it comprises cage bar and end ring, the two ends of cage bar have the pectination notch.The two ends of cage bar can be to be fixed on the end ring after the axial line bending of mouse cage respectively.
The utility model has reduced rotor cage bar end suffered thermal stress when electric motor starting, operation, shutdown cooling greatly, thereby has significantly reduced cage bar phenomenon of rupture, and saved copper material consumption by the improvement to the asynchronous machine cage-shaped structure.
Accompanying drawing has provided embodiment of the present utility model.
Fig. 1 is the structural representation of the utility model cage bar;
Fig. 2 is the structural representation of utility model mouse cage.
With reference to the accompanying drawings the utility model is described in further detail:
With reference to Fig. 1 cage bar 1 of the present utility model as shown, its two ends all have the pectination notch, and its notch can be opened along any direction.With reference to Fig. 2; after being embedded in cage bar 1 on the rotor core 2, present embodiment again cage bar 1 two ends are bent to mouse cage axial line 4; form mouse cage with end ring 3 welding fabrications then; the bending rigidity that this structure makes the axial stiffness of cage bar and cage bar stretch out the rotor core part reduces greatly; thereby the cage bar has reduced the possibility that the fracture of cage bar takes place because of the stress that end ring, copper bar rising-heat contracting-cold cause when reducing electric motor starting, operation, shutdown cooling greatly.
