Abstract
The utility model discloses a motor stator slot wedge structure. A groove (1) is arranged on a stator core stamping sheet; a coil is arranged in the groove (1); a slot wedge is installed at the opening part of the groove (1), namely, the slot wedge mounting part (2), and a concave groove (3) identical to a ventilating duct of a stator iron core is arranged at the ventilating duct part of the stator iron core. In the utility model, due to the adoption of the structure, the influence of the stator slot wedge on an air path at the radial ventilating duct of the stator can be reduced so as to be beneficial to the circulation of the whole air path, the temperature of the motor is reduced to a certain degree, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of electric machine structure, especially relates to a kind of motor stator slot wedge structure.
Background technology
As everyone knows, stator is the critical piece of motor, and stator core is provided with groove, and coil is arranged in the groove, and slot wedge is arranged on the opening part of groove, during installation, is provided with air duct at the stator core segment distance of being separated by, to play cooling effect.At present, stator slot wedge structurally is elongated, and like this, the slot wedge at stator core air duct place will strengthen the windage in the radial ducts, and the wind path in the air duct is had certain influence, thereby influences the air cooling effect.
Summary of the invention
The purpose of this utility model provides a kind of motor stator slot wedge structure that can reduce stator slot wedge to the influence of stator radial ducts place wind path.
The problem of the required solution of the utility model realizes by the following technical solutions: stator core stamping sheet is provided with groove, coil is arranged in the groove, slot wedge is arranged on the opening part of groove, it is characterized in that: the place is provided with the Baltimore groove that matches with the stator core air duct at described stator core air duct.
The structure that the utility model adopts has reduced the influence of stator slot wedge to stator radial ducts place wind path, helps the circulation of whole wind path, can reduce the temperature of motor to a certain extent, increases the service life.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that the structural representation of stator core stamping sheet
Figure 2 shows that the structural representation of stator core stamping sheet groove
Figure 3 shows that the structural representation of stator slot wedge
Figure 4 shows that the sectional view of stator slot wedge
Among the figure 1, groove 2, slot wedge installation place 3, Baltimore groove
Embodiment
By accompanying drawing as can be known, this motor stator slot wedge structure, stator core stamping sheet is provided with groove 1, coil is arranged in the groove 1, slot wedge is installed in the opening part of groove 1, i.e. 2 positions, slot wedge installation place, and the place is provided with the Baltimore groove 3 that matches with the stator core air duct at described stator core air duct.
The utility model is when air cooling, and wind path is through stator radial ducts place the time, owing to have the Baltimore groove that matches with the stator core air duct on the slot wedge, the circulation of whole wind path is more unobstructed, can reduce the temperature of motor to a certain extent.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all execution modes exhaustive, and these belong to conspicuous variation or the change that spirit of the present utility model draws and still are among the protection range of the present utility model.
Claims (1)
