Description
Technical field
The utility model belongs to the modular construction of motor, the more particularly to solid punching of high-power and high-speed motor
Formula rotor.
Background technology
Because the rotor of existing threephase asynchronous is by rotor core, the part such as rotor windings and rotating shaft constitutes, wherein,
Rotor core：As a part for motor magnetic circuit, and rotor windings are placed, typically folded by the punching silicon-steel of 0.5 millimeters thick
Pressure is formed and then is through in rotating shaft；Rotor windings：It produces induced electromotive force and electric current as cutting stator magnetic field, and in rotation
Stress rotates rotor in the presence of turning magnetic field, and the difference according to construction can be divided into squirrel-cage and phase-wound rotor two types.
The need for can't being applied to high-power and high-speed by the existing threephase asynchronous of major limitation of rotor structure, mainly exist
1.5MW, less than 10,000 revs/min using more, 1.5MW can not be met using the design of asynchronous motor, and more than 10,000 revs/min are wanted
Ask.
Current pot-motor mainly has high speed common synchronization motor and high-speed permanent magnetic synchronous motor, both electricity
Though motivation has avoided threephase asynchronous can not meet rotating speed problem high, some problems are there is also：High speed common synchronization
The rotor of motor is winding structure, its manufacture craft and more complicated, the high cost of control, reliability under rotary speed working high
It is low, and low high-speed range during it is mainly；High-speed permanent magnetic synchronous motor can only be limited to permanent-magnet material, and material cost is higher,
Outer ring casing technology difficulty is big, and control is complicated, on the premise of stability and intensity is ensured, is only limitted to work under relatively small power
Make.
The content of the invention
The utility model purpose is to provide a kind of solid Stamped steel type rotor of high-power and high-speed motor, is solved existing
Some threephase asynchronouses due to the limitation of Material Strength, mainly in 1.5MW, less than 10,000 revs/min and be not applied for big
The problem of the high-revolving needs of power；The utility model is adopted the technical scheme that to solve the above problems：High-power high turn
Electric motor with speed includes left rotary shaft, multiple solid punching, right spindles for stacking successively from left to right with solid Stamped steel type rotor,
The rotor slot for setting rotor windings and the first installation perforation for fixing bolt are circumferentially with along circle side in solid punching,
The right-hand member of left rotary shaft be provided with first install punch position it is corresponding second installation perforation, the left end of right spindle be provided with
First installs the 3rd corresponding installation perforation of punch position；The left rotary shaft, multiple solid punchings for stacking, right spindle pass through
Sequentially pass through the second installation perforation, the screw rod that the first installation perforation installs perforation with the 3rd is connected.
Preferably, the multiple solid punching composition solid rotor iron core for stacking, the left rotary shaft and right spindle are constituted
Solid spindle.
Preferably, the solid rotor iron core is connected with the junction of solid spindle using semiaxis ring flange.
The utility model have the advantage that for：Traditional rotor core is stacked using the punching with centre bore
, then rotor core is sleeved in a rotating shaft and rotor is constituted, intensity between this structure punching and rotor
Not enough, it is impossible to meet in 1.5MW, worked under more than 10,000 revs/min operating modes.The utility model replaces original using solid punching
Punching, then securely fixed with left rotary shaft and right spindle by the multiple screw rods on circumferencial direction together with, turn so as to improve
Sub- intensity, substantially increases the power and the range of speeds of motor, disclosure satisfy that 1.5MW, more than 10,000 revs/min of requirement；Expand
The use scope of high-speed asynchronous motor, while also eliminate the height of traditional wire ring type high-speed synchronous motor and permanent-magnet material
The drawbacks of fast synchronous motor.
This solid rotor can be used in combination with common stator, thus this solid rotor when in use need not be to electronic
Other parts of machine are modified, and practicality is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the profile in Fig. 1 along line A-A.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model include successively from left to right left rotary shaft 1, multiple solid punching 3 for stacking,
Right spindle 5, rotor slot 6 for setting rotor windings is circumferentially with and for fixing bolt in solid punching 3 along circle side
First installs perforation 7, is provided with the right-hand member of left rotary shaft 1 and installs the second corresponding installation perforation of 7 positions of perforation with first, on the right side
The left end of rotating shaft 5 is provided with installs the 3rd corresponding installation perforation of 7 positions of perforation with first；The left rotary shaft 1, multiple are stacked
Solid punching 3, right spindle 5 are perforated by sequentially passing through the second installation, first installs the screw rod 4 that perforation is installed in perforation 7 and the 3rd
It is connected；The composition solid rotor iron core of solid punching 3 that so multiple is stacked, naturally it is also possible to set exhausted in solid punching 3
Edge layer, the left rotary shaft 1 and the composition solid spindle of right spindle 5.
Can also be attached using semiaxis ring flange with the junction of solid spindle in the solid rotor iron core.
Traditional rotor core is stacked together using the punching with centre bore, and rotor core then is sleeved on into one
Rotor is constituted in root rotating shaft, insufficient strength between this structure punching and rotor, it is impossible to meet in 1.5MW, 10,000 revs/min
Worked under above operating mode.The utility model replaces original punching using solid punching 3, then by the multiple on circumferencial direction
Together with screw rod 4 is securely fixed with left rotary shaft 1 and right spindle 5, so as to improve rotor strength, the work(of motor is substantially increased
Rate and the range of speeds, disclosure satisfy that 1.5MW, more than 10,000 revs/min of requirement；The use scope of high-speed asynchronous motor is expanded,
The drawbacks of also eliminating the high-speed synchronous motor of traditional wire ring type high-speed synchronous motor and permanent-magnet material simultaneously.
This solid rotor can be used in combination with common stator, thus this solid rotor when in use need not be to electronic
Other parts of machine are modified, and practicality is high.
