At least provided with locating recesses area on the inner wall of keyway;Keyway, first keyway are recorded in a clockwise direction or counterclockwise
It is not provided with locating recesses area, next keyway locating recesses area more than a upper keyway;The locating recesses area is arc
Recessed area.
Preferably, it there are three keyway settings, being recorded from wink clockwise, the first keyway does not have a locating recesses area, and second
A keyway is equipped with a locating recesses area, and second keyway is set there are two locating recesses area.
Preferably, the edge of keyway bottom surface is arranged in the locating recesses area, and is arranged along keyway length direction.
Preferably, on the inner wall of the evenly spaced centrally disposed axis hole of multiple keyways, keyway is along central shaft hole
Axial setting.
The beneficial effects of the utility model are: a kind of rotor punching keyway arrangements that oblique polar angle degree is adjusted are provided, it is adjustable
The rotor punching keyway arrangements for saving oblique polar angle degree can be transformed into a variety of oblique pole structures, be selected by the assembly of dowel hole, segmentation
The sequence of iron core, which adjusts, to be realized, is useful in new product development Qualify Phase, is selected optimal oblique pole mode, can motor be shown
Optimal performance.
