Embodiment Construction

[0033] Please refer to the figures shown, the air gap variable mechanism 10 of the radial flux motor provided in a preferred embodiment of the present invention, it is the inner rotor generator as its specific technical content, and the constituent elements It is mainly composed of a first sub-component 20 as a rotor, a second sub-component 30 as a stator, an annular air gap 40 and a driving part 50 .

[0034] The first sub-part 20 has a first sub-body 21 that is generally columnar, and several diameter-reducing parts 22 formed by elongated sliders that are arc-shaped in cross-section are coaxial and parallel to the first sub-body with the center of curvature. The way of the shaft of the body 21 is that one end 221 is combined on the peripheral side of the first body 21 by a joint part 23, so that the diameter-reducing parts 22 are adjacent to each other, and the diameter-reducing parts 22 can be connected to each other. The convex arc surfaces 222 are connected to each other ...

Abstract

The invention discloses an air gap changing mechanism of a radial magnetic flux type motor. The mechanism comprises a first component, an annular second component, an annular air gap and a driving part, wherein the first component is provided with an outer annular surface; the annular second component coaxially surrounds the circumference of the first component, so that a rotating shaft which is coaxial with centers of curvature of the first component and the second component is used as an axis by the first component and the second component, and the first component and the second component mutually and relatively rotate; the annular air gap is arranged between the inner annular surface of the second component and the outer annular surface of the first component; any one of the first component and the second component is provided with at least two separated cambered reducing parts, the centers of curvature are coaxial with the rotating shaft, and the cambered surface on one side is arranged opposite to the opposite annular surface of the other component to form the air gap between the two surfaces; the reducing parts can move between an open position and a close position in the direction perpendicular to the rotating shaft; and the driving part is used for driving each reducing part to displace between the open position and the close position. When each reducing part moves between each open position and each close position, the width of the air gap can be changed, and further, the magnetic flux density of the air gap can be changed.

Description

technical field [0001] The invention relates to an air gap changing mechanism of a radial magnetic flux motor. Background technique [0002] As far as the technology of using the kinetic energy generated by natural forces such as wind or water to generate electricity is concerned, since these natural forces are rather unstable forces, the output of the generator under the action of these natural forces also presents a relative difference. Stable changing state, therefore, how to stabilize the output of the generator is an urgent problem to be overcome in the technical field of converting natural force into electric energy such as wind power generation, and among them, the method of stabilizing the output through the variable structure of the generator is not a feasible way. [0003] The generator composed of magnets and induction coils properly arranged on the stator and rotor can convert mechanical energy into electrical energy according to Lengz's law. Relative movement ...
