Abstract
The utility model discloses a kind of compressor IPM rotors, including rotor core, permanent magnet and end cap, permanent magnet is inserted directly into tank set on rotor core, end cap is fixedly linked located at the two ends of rotor core and permanent magnet and respectively by rivet with rotor core, rotor core circumferential surface offers groove, can avoid rotor core that saturated phenomenon occurs because of high-magnetodensity, so as to improve electric efficiency, it is ensured that the high performance operation of motor.
Description
Technical field
The utility model is related to a kind of electric moto used in compressor rotor, specifically a kind of Permanent Magnet and Electric for compressor
The IPM rotors with notching construction on machine.
Background technology
At present, the use within the compressor of IPM magnetoes is more universal.Due to built-in permanent magnetic body（IPM）Turn
The permanent magnet of son is located at internal rotor, thus such rotor has the low feature of simple structure, high mechanical strength, rotary inertia,
And permanent magnetism shape and the free degree of configuration are higher.But at the same time, existing IPM rotors are generally also present one and significantly lack
Point, i.e. the magnet steel magnetic at the position of rotor core circumferential surface are close higher, and silicon steel sheet is susceptible to saturation, and then influences motor
Efficiency.
The content of the invention
Technical problem to be solved in the utility model is to propose that one kind can avoid rotor that saturation occurs because of high-magnetodensity
Phenomenon, so that it is guaranteed that the compressor of the high performance operation of motor IPM rotors.
In order to solve the above technical problems, a kind of compressor of the utility model with IPM rotors include rotor core, permanent magnet and
End cap, the permanent magnet is inserted directly into tank set on the rotor core, the end cap located at the rotor core and
The two ends of the permanent magnet are simultaneously fixedly linked with the rotor core respectively, and the rotor core circumferential surface offers groove.
A kind of above-mentioned compressor IPM rotors, set tank is tile-type groove on the rotor core, and the permanent magnet is inserted
Enter in the tile-type groove.
A kind of above-mentioned compressor IPM rotors, the groove that the rotor core circumferential surface is opened up is rectangular channel.
A kind of above-mentioned compressor IPM rotors, the end cap is fixedly linked by rivet with the rotor core.
Due to using above-mentioned technical pattern, rotor core circumferential surface is provided with groove, can be used to avoid rotor the utility model
There is saturated phenomenon because of high-magnetodensity in iron core, so as to improve electric efficiency, it is ensured that the high performance operation of motor.Tile-type groove is used for
Lay permanent magnet, it is ensured that rotor overall mechanical strength, improve the reliability of motor operation.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model compressor includes rotor core 1 and end cap 6, end cap with IPM rotors
6 include upper and lower two, are respectively arranged on the two ends of rotor core 1, and two end caps 6 are riveted solid by rivet 2,4 and rotor core 1
It is fixed to be connected.Rectangular channel 5 is offered on the circumferential surface of rotor core 1, can be used to avoid rotor core 1 from satisfying because of high-magnetodensity
And phenomenon.
As shown in Figure 4, Figure 5 and Figure 6, the utility model compressor IPM rotors also include permanent magnet 3, in rotor core 1
Shoe groove is offered as tank, permanent magnet 3 is inserted directly into tile-type groove, and permanent magnet 3 is embedded in the inside of rotor core 1.Forever
Magnet 3 is simultaneously the spacing fixation of two end caps 6.
Be securely fixed in permanent magnet 3 inside rotor core 1 by the utility model, and permanent magnet 3 can be avoided during high-speed rotation
With the relative motion between rotor core 1, so as to improve the reliability of motor operation.Meanwhile, the end cap 6 of both sides can directly pass through
The riveting of rivet 4 is got up, and assembly process process is good.Rectangular channel 5 is provided with the circumferential surface of rotor core 1, can be used to avoid rotor iron
There is saturated phenomenon because of high-magnetodensity in core, so as to improve electric efficiency.
In the utility model structure, the vessel shape of permanent magnet can as needed with the shape of permanent magnet on rotor core
It is changed.The quantity of permanent magnet and the quantity of tank can also be changed according to design needs.Institute on rotor core circumference
If groove its shape can have any shape, the quantity of groove can also be changed as needed.
