Abstract
The utility model relates to a motor stator, rotor air duct structure, comprising a groove plate and groove slices arranged on the two ends of the groove plate, wherein the groove slice is formed by laminating a plurality of slices and each slice is welded and contacted with the groove plate. The contact area between the groove slice and the groove plate is increased, after spot-welding, the deformation of the groove plate is relatively small, the lamination factor of iron cores is increased, the rotor iron consumption is reduced, the operation temperature is reduced, therefore the motor efficiency is increased; simultaneously the groove plates use the magnetic conductive material of the same trademark of the stator, rotor iron punch pieces, thus the effective availability of the material of the stator, rotor iron cores is increased and the efficiency of the motor is increased.
Description
Technical field
The utility model relates to a kind of electric machine rotor air duct structure.
Background technology
Its form of air duct structure of motor is the slotted vane made from steel plate at present; Be welded with the frid made from steel plate, the defective of its existence is: 1) contact area of slotted vane and frid is little, causes the welding deformation of frid easily; Reduce the stack coefficient of rotor core; Rotor iron loss rises, the rotor core heating, and electric efficiency reduces; 2) because frid is made by steel plate, the effective magnetic conduction volume of the rotor of motor is reduced.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide a kind of electric machine rotor air duct structure that improves rotor core stack coefficient.
The technical scheme of the utility model employing is for this reason: the utility model comprises frid and the slotted vane that is arranged on the frid two ends, and said slotted vane is formed by stacking the multi-disc lamellar body, and said each lamellar body contacts with frid.
The utility model has the advantages that: slotted vane of the utility model and frid contact area increase, and the distortion of spot welding drop end is less, can improve patent stack coefficient unshakable in one's determination, reduce rotor iron loss, and its operating temperature is descended, thereby improve electric efficiency; The utility model frid is used instead and the permeability magnetic material of rotor punching with the trade mark simultaneously, and the effective rate of utilization of the material of stator and rotor cores is improved, and efficiency of motor will be improved.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of existing air duct.
1 is that slotted vane, 2 is frid among the figure.
Embodiment
The utility model comprises frid 2 and the slotted vane 1 that is arranged on frid 2 two ends, and the slotted vane 1 of the utility model is formed by stacking the multi-disc lamellar body, and said each lamellar body contacts with frid 2.
Claims (1)
1. electric machine rotor air duct structure comprises frid and the slotted vane that is arranged on the frid two ends, it is characterized in that said slotted vane is formed by stacking the multi-disc lamellar body, and said each lamellar body contacts with frid.
