Abstract
The invention relates to a stator punching piece for a high voltage motor. Stator punching piece slots which are symmetrical in the left-right direction are evenly arranged on an inner circle of a stator punching piece body. The left-right symmetrical center line of the stator punching piece slots are arranged in the radial direction of the stator punching piece body. In the cross section of the stator punching piece body, each stator punching piece slot comprises a stator punching piece slot outer section, a stator punching piece slot middle section and a stator punching piece slot inner section. The inner end portion of the stator punching piece slot outer section is connected with the outer end portion of the stator punching piece slot middle section, and the inner end portion of the stator punching piece slot middle section is connected with the outer end portion of the stator punching piece slot inner section. The stator punching piece slot outer section and the stator punching piece slot inner section are rectangular, the middle portion edge of the stator punching piece slot middle section in the height direction is embedded in the stator punching piece body on one corresponding side, the width of the stator punching piece slot outer section is identical with that of the stator punching piece slot inner section, and the inner end portion of the stator punching piece slot inner section is connected with an inner circle of the stator punching piece body. The stator punching piece has the advantages of being small in electromagnetic noise, small in starting current, small in temperature rise and the like.
Description
Technical field
The present invention relates to a kind of stator punching, especially a kind of high-voltage motor is used stator punching.
Background technology
Because original traditional design is not considered the high-voltage motor of height of center 315; The domestic in the past motor that does not just have height of center 315; Also do not have standardization, seriation design, domestic high-voltage motor that can't shopping center high 315 all was through import ABB AB, Siemens Company in the past; This a kind of design at present can be satisfied the blank that can fill up domestic height of center 315 high pressure.Be widely used in the motor in the fields such as industry, agricultural, commerce, building industry and traffic at present.
Stator punching is the key components and parts in the motor, its material, interior round size, excircle dimension, flute profile size, flute profile what etc. efficiency of motor is had direct influence.And use maximum Y series high voltage motor, its stator punching can't reach the purpose of high 315 motors in design centre in the market, and realize that in long-term use also there are defectives such as electromagnetic noise is big, starting current is big, temperature rise height in it.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide that a kind of electromagnetic noise is little, the little high-voltage motor that heats up is used stator punching.
According to technical scheme provided by the invention; Said high-voltage motor is used stator punching, comprises the stator punching body, on the interior circle of stator punching body, evenly offers to 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, said stator punching groove comprises the outer section of stator punching groove, stator punching groove stage casing and stator punching groove inner segment, and 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 a rectangle, and the edge, middle part of stator punching groove miding level height direction is embedded in to the stator punching body of a corresponding side, and stator punching groove inner segment is a rectangle; The outer section of stator punching groove is identical with stator punching groove inner segment width, and the interior circle of the inner end of stator punching groove inner segment and stator punching body joins.
The height in said stator punching groove stage casing is 4 ~ 5mm.
The height of said stator punching groove inner segment is 0.9 ~ 1.1mm.
On the interior circle of stator punching body, evenly offer 48 or 72 stator punching grooves.
The present invention has that electromagnetic noise is little, starting current is little and the advantage such as little that heats up.
