Embodiment
In order to make the technical solution of the utility model clearer, below in conjunction with accompanying drawing, rotor of the present utility model, motor and compressor are described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model and to be not used in restriction the utility model.
Referring to Fig. 1 to Fig. 6, rotor of the present utility model comprises rotor core 1, a plurality of balance weight 2 and magnet steel 3.Wherein, a plurality of balance weights 2 are separately positioned on the two ends of rotor core 1, and rotor core 1 is used identical material cast solid with balance weight 2, form integrated rotor core group, balance weight 2 is for balancing rotor iron core 1, and magnet steel 3 is sleeved in integrated rotor core group, forms rotor.
Due to rotor core and the integrated design of balance weight, in the assembling process of rotor, do not need to use screw that balance weight is fixed on rotor core, only magnetic steel sleeve need to be contained on rotor core, like this, not only simplify the assembly process of rotor, improved the assembling beat of rotor, and avoided the problem that in assembling process, rotor is out of shape, improved the quality of rotor, and then guaranteed that motor has good service behaviour.
More preferably, the material of rotor core 1 and balance weight 2 is soft magnetic material, makes like this performance of motor obtain certain lifting.It should be understood that soft magnetic material refers to when magnetization occurs in Hc and is not more than 1000A/m.Soft magnetic material is the magnetic material that (soft magnetic material) has low-coercivity and high magnetic permeability.Soft magnetic material is easy to magnetization, is also easy to demagnetization, is widely used in electrical equipment and electronic equipment.Typical soft magnetic material, can realize by minimum external magnetic field the maximum magnetization.Applying maximum soft magnetic materials is ferro-silicium (silicon steel sheet) and various soft magnetic ferrites etc.
As a kind of embodiment, the center of rotor core 1 is provided with the axis hole suitable with rotating shaft, balance weight 2 and the concentric setting of rotor core 1.More preferably, the quantity of balance weight 2 is two, is respectively main balance weight and secondary balance weight.Wherein, main balance weight arranges the first end of rotor core 1, and secondary balance weight is arranged on the second end of rotor core 1, can guarantee like this balance at rotor two ends in the process of rotor running.In the present embodiment, the shape of main balance weight and secondary balance weight is semicircle annular, and main balance weight and secondary balance weight are oppositely arranged.
More preferably, the external diameter of main balance weight equals the external diameter of rotor core, and the internal diameter of main balance weight is less than the internal diameter of rotor core.The external diameter of secondary balance weight is greater than the external diameter of rotor core, and the internal diameter of secondary balance weight equals the internal diameter of rotor core.
More preferably, all sides of rotor core 1 are provided with lug boss 11.Magnet steel 3 is annular, on the interior week of magnet steel 3, be provided with rotor core 1 on the magnet steel groove 31 that matches of lug boss.Make like this assembling of magnet steel comparatively firm, the service behaviour that assurance can motor, and easy to install.
