Description
Technical field
The utility model relates to a kind of stator punching, especially a kind of high-voltage motor stator punching.
Background technology
Because original traditional design is not considered the high-voltage motor at center high 315, domestic just less than the motor at center high 315 in the past, also do not have standardization, Seriation Design, domestic high-voltage motor that can't shopping center high 315 all was by import ABB AB, Siemens Company in the past; At present this a kind of design can be satisfied the blank that can fill up high 315 high pressure in domestic center.Be widely used at present the motor in the fields such as industry, agricultural, commerce, building industry and traffic.
Stator punching is the key components and parts in the motor, its material, inner circle size, excircle dimension, flute profile size, flute profile what etc. the efficient of motor is had direct impact.And use in the market maximum Y-series high-tension motors, its stator punching can't reach the purpose of high 315 motors in design centre, and realize that in long-term use procedure also there are the defectives such as electromagnetic noise is large, starting current is large, temperature rise is high in it.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the high-voltage motor stator punching that a kind of electromagnetic noise is little, intensification is little is provided.
The technical scheme that provides according to the utility model, described high-voltage motor stator punching, comprise the stator punching body, on the inner circle of stator punching body, evenly offer and be symmetrical stator punching groove, the left-right symmetric center line of stator punching groove is along the radially setting of stator punching body, in the cross section of stator punching body, described stator punching groove comprises the outer section of stator punching groove, stator punching groove stage casing and stator punching groove inner segment, the inner end of the outer section of stator punching groove and the outer end in stator punching groove stage casing join, the outer end of the inner end in stator punching groove stage casing and stator punching groove inner segment joins, the outer section of stator punching groove is rectangle, the edge, middle part of stator punching groove miding level height direction is embedded in to the stator punching body of a corresponding side, stator punching groove inner segment is rectangle, the outer section of stator punching groove is identical with stator punching groove inner segment width, and the inner circle of the inner end of stator punching groove inner segment and stator punching body is joined.
The height in described stator punching groove stage casing is 4 ~ 5mm.
The height of described stator punching groove inner segment is 0.9 ~ 1.1mm.
On the inner circle of stator punching body, evenly offer 48 or 72 stator punching grooves.
The utlity model has that electromagnetic noise is little, starting current is little and the advantage such as little that heats up.
