Description
Technical field
The utility model belongs to the modular construction of motor, and more particularly to high-power and high-speed asynchronous motor is with solid
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；Rotor windings：It produces induced electromotive force and electric current as cutting stator magnetic field, and in the presence of rotating excitation field
Stress rotates rotor, and the difference according to construction can be divided into squirrel-cage and phase-wound rotor two types.By the master of rotor structure
Limiting existing threephase asynchronous can't be suitable for the need for high-power and high-speed, mainly in 1.5MW, 10,000 revs/min
Below using more, 1.5MW, more than 10,000 revs/min of requirement can not be met using the design of asynchronous motor.
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 high-power and high-speed asynchronous motor solid rotor, is solved existing
Threephase asynchronous due to the limitation of Material Strength, mainly in 1.5MW, less than 10,000 revs/min and be not applied for big work(
The problem of the high-revolving needs of rate；The utility model is adopted the technical scheme that to solve the above problems：High-power and high-speed
Asynchronous motor solid rotor, including integrally formed solid rotor iron core and solid spindle, the edge on solid rotor iron core
Circle side is circumferentially uniformly machined with multiple rotor slots for setting rotor windings, the two ends of solid rotor iron core be machined with for
The end ring groove of end ring is installed.
Preferably, the sliver of rotor windings is welded in rotor slot；The end ring welding is in end ring groove.
Preferably, the solid rotor iron core and solid spindle are made using copper material.
The utility model have the advantage that for：Because solid rotor iron core and solid spindle are integrally formed, and
It is directly to be processed in solid rotor iron core that rotor slot closes end ring groove, instead of traditional Stamped steel type rotor structure, so that
Rotor strength is improve, the power and the range of speeds of motor is substantially increased, 1.5MW, more than 10,000 revs/min is disclosure satisfy that
It is required that；The use scope of high-speed asynchronous motor is expanded, while also eliminating traditional wire ring type high-speed synchronous motor and forever
The drawbacks of high-speed synchronous motor of magnetic material.The sliver and end ring of solid rotor winding using welding by the way of and solid rotor
Iron core 3 is connected, and further increases the intensity of this solid rotor.
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 includes integrally formed solid rotor iron core 3 and solid spindle 1, described
Solid rotor iron, 3 and solid spindle 1 made using copper material, be uniformly machined with along circle side is circumferential on solid rotor iron core 3
Multiple is used to set the rotor slot 5 of rotor windings, and the end ring for installing end ring 2 is machined with the two ends of solid rotor iron core 3
Groove.
In order to further increase the intensity of rotor, the sliver 4 of solid rotor winding is welded in rotor slot 5；The end ring 2
It is welded in end ring groove.
Because solid rotor iron core 3 and solid spindle 1 are integrally formed, and it is directly solid that rotor slot 5 closes end ring groove
What rotor core 3 was processed, traditional Stamped steel type rotor structure is instead of, so as to improve rotor strength, substantially increase
The power and the range of speeds of motor, disclosure satisfy that 1.5MW, more than 10,000 revs/min of requirement；Expand high-speed asynchronous motor
Use scope, while also eliminating the disadvantage of the high-speed synchronous motor of traditional wire ring type high-speed synchronous motor and permanent-magnet material
End.
The sliver 4 and end ring 2 of solid rotor winding are connected by the way of welding with solid rotor iron core 3, further
Increased the intensity of this solid rotor.
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.
Finally it should be noted that：Above example is only used to illustrate the technical solution of the utility model, rather than its limitations；
Although being described in detail to the utility model with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement, but these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technology of the utility model
The spirit and scope of scheme.
