Abstract
The utility model discloses an outer rotor assembly device of a DC brushless motor. The outer rotor assembly device of the DC brushless motor includes an iron coil, a metal connection plate arranged on an end of the iron coil and having no magnetic permeability, a shaft sleeve, a shaft and a permanent magnet installed on the inner wall of the iron coil concentrically. The metal connection plate having no magnetic permeability is a stainless steel plate or a cast aluminum plate. Since a prior iron connection plate having magnetic permeability on the end of the iron core is replaced with the stainless steel plate or the cast aluminum plate having no magnetic permeability, magnetic flux leakage of the permanent magnet installed on the inner wall of the iron coil in a pasted manner is prevented. The outer rotor assembly device of the DC brushless motor in the utility model is suitable for applying widely.
Description
Technical field
The utility model relates to a kind of dc brushless motor, especially a kind of dc brushless motor external rotor assembly apparatus.
Background technology
Existing dc brushless motor external rotor assembly apparatus is to be shaped at iron ring one end to connect iron plate, connects iron plate central authorities and is shaped on axle sleeve; Axle sleeve central authorities are fixed with axle; Permanent magnet is mounted on the iron ring inwall with one heart, because the connection iron plate of iron ring one end is a magnetic conductor, can produce certain leakage field phenomenon; Thereby influence the dc brushless motor overall performance, this is need be improved.
The utility model content
The technical problem that the utility model will solve provides a kind of can reaching and neatly is bonded in permanent magnet on the iron ring inwall, and the dc brushless motor that can prevent and reduce the leakage field phenomenon again changes assembly apparatus outward.
For solving the problems of the technologies described above, the utility model comprises iron ring, and iron ring one end is shaped on connecting plate; Axle sleeve, axle and be contained in the permanent magnet of iron ring inwall with one heart; Connecting plate is processed by non-magnetic metal material, and a kind of of non-magnetic metal material is corrosion resistant plate, and non-magnetic metal material another kind is a cast aluminium; Because connection iron plate magnetic conductor with iron ring one end; Change non-magnetic corrosion resistant plate or cast aluminium into, can not produce the leakage field problem to the permanent magnet that is mounted on the iron ring inwall, the utility model is adapted at using in the various dc brushless motor external rotor assembly apparatus.
Description of drawings
Fig. 1 is that a kind of dc brushless motor external rotor of the utility model assembly apparatus adopts stainless steel connecting plate embodiment generalized section;
Fig. 2 is that a kind of dc brushless motor external rotor of the utility model assembly apparatus adopts cast aluminium connecting plate embodiment generalized section.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1, the utility model comprises iron ring 2, and iron ring 2 one ends are shaped on stainless steel connecting plate 1; Stainless steel connecting plate 1 central authorities' system is with axle sleeve 4; The fastening axle 5 that is equipped with of axle sleeve 4 central authorities, magnetic shoe 3 is mounted on iron ring 2 inwalls with one heart, thereby forms the dc brushless motor external rotor assembly apparatus of one group of few leakage field.
Referring to Fig. 2, the utility model comprises iron ring 7, and iron ring 7 one ends are shaped on cast aluminium connecting plate 6; Cast aluminium connecting plate 6 central authorities are shaped on axle sleeve 8; The fastening axle 5 that is equipped with of axle sleeve 8 central authorities, magnetic shoe 3 is mounted on iron ring 7 inwalls with one heart, thereby forms the dc brushless motor external rotor assembly apparatus of one group of few leakage field.
