    Rotor for Brushless Motor
    The present invention relates to a rotor, and more particularly to a rotor for a brushless motor applied to the compressor.
    In general, the compressor is discharged by changing the refrigerant flowing in the evaporator to a high temperature, high pressure bar, a brushless motor is installed to operate the compressor.
    As shown in FIG. 3, the compressor includes a housing 50 in a sealed state, a stator 51 fixed inside the housing 50, and a rotatable inside the stator 51. It is comprised by the installed rotor 52 and the valve assembly 55 which was connected to the said crankshaft 53 of the said rotor 52, and operated so that refrigerant may flow in from the accumulator 54. As shown in FIG.
    Here, the rotor 52 has a core 57 into which the crankshaft 53 is inserted, as well as a plurality of magnets 56 inserted and fixed as shown in FIG. 4, and the core 57 described above. An end plate 58 in close contact with an upper portion of the magnet to prevent the magnet from being separated, a balance 59 attached to the end plate 58 to maintain a rotational balance of the core 57, and the balance 59 described above. It is composed of an upper plate 60 in close contact with the upper surface of the oil to prevent the oil from being dispersed when the oil is ejected to the upper surface through the core 57, and a rivet 61 for fixing the plurality of parts to the core 57. have.
    That is, the rotor 52 is configured by sequentially stacking the end plate 58, the balance 59 and the upper plate 60 on the core 57 and then fixing it with a rivet 61.
    However, as described above, when the rotor is composed of the end plate, the upper plate, the balance and the core, the rotor is complicated and the one side of the upper plate is spaced apart from the core. There is a problem that noise occurs.
    Accordingly, an object of the present invention to solve the above problems, to simplify the configuration of the rotor, and to provide a rotor for a brushless motor that can reduce the noise and vibration during rotation.
    In order to achieve the above object, the present invention provides a brushless motor rotor in which a plurality of magnets are inserted into a core, and is in close contact with one side of the core, and a balance is inserted and a magnet inserted into the core is not separated. And a fixing member for fixing the plate to the core, and a plate having a supporting portion for blocking the block.
    1 is a perspective view showing a rotor for a brushless motor according to the present invention;
    2 is a cross-sectional view taken along the line A-A in FIG.
    3 is a cross-sectional view showing a compressor application state of a general brushless motor;
    4 is an exploded perspective view showing the rotor in FIG.
    ＊ Explanation of symbols on main parts of drawing
    1: insertion part 2: plate
    3: rivet 4: support
    57: core 59: balance
    1 and 2 are a perspective view showing a rotor for a brushless motor according to the present invention and a cross-sectional view taken along the line AA of FIG. 1, in which the core 57 is in close contact with the upper surface of the core 57 and a balance 59 is shown. ) Is inserted into the plate (2) formed integrally with the cylindrical inserting portion (1) to block the magnet 56 inserted in the core 57 is not separated, the core 57 and the plate (2) And a fixing member such as a rivet (3) for fixing through the balance (59).
    In particular, the support portion 4 is formed on the opposite side of the insertion portion 1 of the plate 2 so that the core 57 and the plate 2 are not separated from each other and the magnet 59 is not separated.
    That is, since the bottom surface of the insertion part 1 and the support part 4 blocks the magnet 59 inserted in the core 57 from the upper surface, the magnet 59 is not required to install the conventional end plate 58. It is possible to prevent the departure of.
    Of course, even if the support portion 4 is formed on the bottom surface of the plate 2 as a whole, and the balance 59 is attached, the separation prevention effect of the magnet 56 is the same, but the fixing force of the balance 59 is lowered.
    When explaining the operation and effect of the present invention as described above, the operator inserts the balance 59 in the insertion portion 1 of the plate 2 to assemble the rotor.
    When the balance 59 is inserted, the plate 2 is positioned on the upper surface of the core 57 and the rivet 3 is fixed thereto.
    At this time, the bottom surface of the insertion portion 1 and the support portion 4 is to cover the upper surface of the magnet 56 of the core 57, the insertion portion 1 and the support portion 4 is a conventional end plate (58) to play the role.
    That is, the configuration of the rotor can be simplified by being able to prevent the magnet 56 from being separated by the insertion portion 1 and the support portion 4 without using the end plate 58.
    When the rotor is mounted on the compressor to operate the rotor as described above, the rotor rotates at a constant speed. During the rotation, the insertion part 1 serves as a side and bottom support of the balance 59. The support part 4 is in close contact with the core 57 to block the upper and lower vibrations of the plate 2, thereby reducing vibration and noise.
    As described above, the present invention has the advantage of simplifying the configuration of the rotor by configuring the plate to prevent the departure of the magnet without installing an end plate that is tightly fixed to the upper surface of the core in the rotor of the brushless motor It is.
