Abstract
The utility model discloses a cast-aluminum rotor used for a micro motor. The cast-aluminum rotor used for the micro motor comprises an iron core, wherein the iron core has a bearing hole, a side face of the iron core is provided with a plurality of cast-aluminum holes in a circumferential direction, each cast-aluminum hole is casted with aluminum material, two sides of the iron core are respectively provided with an aluminum ring, the aluminum rings are located on the cast-aluminum holes, and the side face of the iron core is provided with six through-holes. The cast-aluminum rotor used for the micro motor has a simple structure and is convenient to process; the rotor is symmetrical along a center axis, so balance performance is relatively strong; and through-holes are arranged on the rotor, so a heat radiation effect is good.
Description
Technical field
The utility model relates to a kind of cast-aluminum rotor for micromachine.
Background technology
Rotor twines copper cash or insertion magnet steel with rotor core usually in order to form and the interactional rotating magnetic field of the rear generation of stator energising when the processing rotor, reach the effect of rotor with this.The problem that exists is: rotor core twines the production process that copper cash has increased rotor, has improved the cost of rotor; Rotor core inserts the problem that then there is fail safe in magnet steel, because rotor throws away magnet steel in the high speed rotating process easily; Also useful cast-aluminum rotor on the market, but rustic, balance is poor, and radiating effect is poor.Above-mentioned complex rotor structure is not suitable for use in the rotor of micromachine.
The utility model content
The purpose of this utility model is to provide a kind of cast-aluminum rotor for micromachine, makes this cast-aluminum rotor structure simple, easy to process, and can solve the problem that balance is poor, radiating effect is poor.
To achieve these goals, the technical solution of the utility model is: a kind of cast-aluminum rotor for micromachine, comprise iron core, has dead eye on this iron core, also along the circumferential direction be provided with some cast aluminiums hole in the iron core side, each cast aluminium hole top casting has aluminium, respectively is provided with an aluminium ring in the iron core both sides, described aluminium ring is positioned on the cast aluminium hole, and described iron core side is provided with 6 ventilation holes.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to process, and rotor is symmetrical along central shaft, has stronger balance, has ventilation hole, good heat dissipation effect on the rotor.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in the figure: a kind of cast-aluminum rotor for micromachine, comprise iron core 7, has dead eye 6 on this iron core 7, also along the circumferential direction be provided with some cast aluminiums hole 1 in iron core 7 sides, each cast aluminium hole 1 top casting has aluminium, respectively be provided with an aluminium ring 4 in iron core 7 both sides, described aluminium ring 4 is positioned on the cast aluminium hole 1, and described iron core 7 sides are provided with 6 ventilation holes 3.
When the utility model uses, in the energising situation, produce interactional rotating magnetic field between the aluminium of rotor and the stator coil, thereby rotor driven rotates.
