Abstract
The utility model discloses a motor rotor for a range hood, which is used in a permanent-magnet micro motor of a range hood. The motor rotor is composed of a rotor body and a rotating shaft, wherein the rotor body comprises a rotor outer ring and a rare-earth magnetic steel circular ring; the rotor outer ring is bonded on the rare-earth magnetic steel circular ring by glue, and is mounted on the rotating shaft together with the rare-earth magnetic steel circular ring; the rotating shaft is a cylindrical cast iron rotating shaft; and the tail end of the rotating shaft is provided with a bolt. The motor rotor for a range hood has the advantages of simple structure, stable performance, high power, low energy consumption and long service life.
Description
Technical field:
The utility model relates to a kind of improvement of rotor, relates in particular to a kind of soot motor rotor.
Background technology:
The improvement of Along with people's growth in the living standard and housing condition, kitchen hood has been the thing of indispensability in the cooking apparatus.At present; Lampblack absorber on the market adopts permanent magnet micro motor more, and the type motor comprises by stator and rotor and forming; Rotor is embedded in the iron core surface or is embedded core interior by the permanent magnet of certain number of pole-pairs and constitutes; The prior motor rotor core needs that steel disc entangles, the material of rotor adopts silicon steel sheet more, adopts the mode of aluminium weldering to be welded, and such motor rotor construction complicacy, less, the easy damage of power, useful life lack.
The utility model content:
The utility model is to the deficiency of existing soot motor rotor technology, and purpose is to provide a kind of soot motor rotor, has simple in structure, stable performance, power is big, energy consumption is little, the advantage of long service life.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of soot motor rotor is made up of rotor block and rotating shaft, it is characterized in that: rotor block comprises rotor exterior ring, rare earth magnetic steel annulus, and rotor exterior ring is bonded on the rare earth magnetic steel annulus through glue, is installed in the rotating shaft together with the rare earth magnetic steel annulus;
Described rotating shaft is cylindrical pig iron rotating shaft, and the end of rotating shaft is provided with bolt.
The beneficial effect of the utility model is:
1. rotor block adopts the rare earth magnetic steel material, and power is big, the motor configuration of same model, can from before 45W bring up to 80W, energy consumption is little, can practice thrift 2/5 electric weight.
2. adopt the pig iron to do rotating shaft, substitute existing iron core and add the steel disc structure, simple in structure, cost is low, and long service life.
Description of drawings:
Fig. 1 is the front view of the utility model structural representation;
Fig. 2 is the utility model structural representation.
Among the figure: 1, rotor block, 2, rotating shaft, 3, rotor exterior ring, 4, the rare earth magnetic steel annulus, 5, bolt.
Embodiment:
Embodiment: see illustrated in figures 1 and 2; A kind of soot motor rotor is made up of rotor block 1 and rotating shaft 2, and rotor block comprises rotor exterior ring 3, rare earth magnetic steel annulus 4; Rotor exterior ring 3 is bonded on the rare earth magnetic steel annulus 4 through glue, is installed in the rotating shaft 2 together with rare earth magnetic steel annulus 4; Rotating shaft 2 is cylindrical pig iron rotating shaft, and the end of rotating shaft 2 is provided with bolt 5, and bolt 5 can be fixed rotor.
