Abstract
A kind of rotor core structure and compressor, the rotor core structure includes rotor core and several magnetic slots being located on rotor core, further include the dowel of at least one expansion slot being located at around the magnetic slot and the separation magnetic slot and the expansion slot, the dowel can deform under external force.In high-speed rotation, the air in expansion slot can be heated the motor of the present invention, to make dowel deform, magnetic slot clamping, achieve the effect that magnet steel will not shift, to reduce the noise of vibration, the probability for also reducing motor demagnetization, increases security performance.
Description
Technical field
The present invention relates to compressor field, more specifically a kind of rotor core structure and compressor.
Background technology
In inverter compressor motor field, generally use permanent magnet synchronous motor, the V-type magnet steel of permanent magnet synchronous motor at present
Structure efficiency is high, is widely used by industry.But when motor speed is larger, radial deflection can occur in magnetic slot for magnet steel,
To generate prodigious vibration noise, product quality is affected, and has larger security risk, also makes the demagnetization probability of motor
Increase.
In this field, designs a rotor core that can prevent magnet steel from radial deflection occurring in magnetic slot and compel in eyebrow
Eyelash.
Invention content
The object of the present invention is to provide a kind of rotor core structure and compressor, which makes motor in height
When speed rotation, magnet steel will not shift, and reduce the noise of vibration, increase security performance.
In order to achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of rotor core structure, including rotor core and several magnetic slots being located on iron core, it is characterised in that：Further include setting
The dowel of at least one expansion slot and the separation magnetic slot and the expansion slot around the magnetic slot, the company
Connecing muscle can deform bearing external force.
Preferably, the expansion slot is located at side of the magnetic slot close to the rotor core center of circle.
Preferably, the expansion slot is through-hole.
Preferably, the thickness of the dowel is uniform.
Preferably, the thickness of the dowel is 0.2-0.25mm.
Preferably, the length of dowel is less than the 1/5 of magnetic slot total length.
Preferably, the expansion slot is rectangular or triangle.
Preferably, the magnetic slot is uniformly distributed around the center of circle of the rotor core.
The present invention also protects a kind of compressor including above-mentioned rotor core structure.
Preferably, the compressor is frequency-changeable compressor.
Compared with prior art, the present invention at least has the advantages that：
The rotor core structure and compressor of the present invention so that for motor in high-speed rotation, the air being located in expansion slot can quilt
Heating, to make dowel deform, magnetic slot clamping, achievees the effect that magnet steel will not shift, to reduce vibration
Noise, also reduce motor demagnetization probability, increase security performance.

Specific implementation mode
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1 shown in -2, a kind of rotor core structure provided for an embodiment, including rotor core 1, magnetic slot 2,
Magnetic slot 2 is equally distributed around the center of circle of rotor core, is used for mounting magnetic steel, several expansion slots are additionally provided on magnetic slot
3, quantity according to circumstances depending on, expansion slot 3 is located at magnetic slot towards the side in the axle center of rotor core, in expansion slot 3 and magnetic
Part between steel tank 2 is dowel 4.The matched heating rod of this rotor core structure in the rotor between hole be inserted into rotor
In iron core, high-temperature heating makes the temperature of rotor core constantly increase, rotor core expanded by heating so that the gas in expansion hole
Also can expanded by heating, to make dowel 4 be deformed to magnetic slot by expansive force, the dowel of deformation fixes magnet steel so that turns
During running at high speed, magnet steel will not shift son, reduce the noise that vibration is sent out, and also reduce the general of motor demagnetization
Rate, while also improving its security performance.
In the present embodiment, expansion slot 3 is through-hole structure, has passed through two end faces of rotor core.Wherein in order to heat
Afterwards, the deformation of dowel is more uniform, and the thickness of dowel 4 is uniformly arranged, and the thickness of dowel is located between 0.2mm-0.25mm,
If the thickness of dowel is excessive, the deformation extent of expansion hole is too small, bad to the fixed effect of magnetic slot.In order not to make due to
Deform it is excessive, and the phenomenon that causing dowel to be broken occur, the length of dowel is set smaller than the 1/5 of magnet steel slot length.
In some other embodiment, the shape of expansion slot 3 can be rectangular, triangle or polygon, can also
It is some abnormity, but can all achievees the effect that above-mentioned.
The present invention also protects a kind of compressor, which is frequency-changeable compressor, it is used with expansion slot and connection
The structure of the rotor core of muscle, it reduces the noise of motor, also reduces the probability of the demagnetization of motor, improves the peace of equipment
Full performance.
Above by specific embodiment, invention is explained in detail, these detailed description are only limited to help
Those skilled in the art understand that present disclosure, can not be interpreted as limiting the scope of the invention.Art technology
Personnel should be included in various retouchings, equivalent transformation etc. that said program carries out under present inventive concept the protection model of the present invention
It encloses.
