Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure where a rotor core and a stator core are made contact each other with bearing balls, which utilizes the fact that a method of direct contacting, with no air gap, is most effective to maintain magnetic flux density with no reduction. <P>SOLUTION: A required number of bearing balls are inserted for well balance in the gap between an iron core and an N/S core. The axes of bearing balls are connected/fixed with a non-magnetic body, or the axes of bearing balls are fixed to a stator core or a rotor core for point or line contacting, resulting in smooth rotational movement. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、発電機（励磁式、磁石式）及び、モータに関し、固定子コアと回転子コアを有するタイプの電動機では、必ずエアーギャップが存在するが、高い磁束を維持させる手段として、透磁率の高いベアリングを鉄心コア部とＮ・Ｓコア部との間に挿入し、直接接触（点又は、線接触）させ、エアーギャップを無くす構造に関する。
The present invention relates to a generator (excitation type, magnet type) and a motor. In an electric motor of a type having a stator core and a rotor core, an air gap always exists, but magnetic permeability is used as means for maintaining a high magnetic flux. The present invention relates to a structure in which a high-bearing bearing is inserted between an iron core portion and an NS core portion and directly contacted (point or line contact) to eliminate an air gap.

発電機及び、モータの構造には固定子コアと回転子コアを有するタイプの場合、鉄心コア（コイルが巻かれた鉄心）部と、Ｎ・Ｓコア（励磁式又は、永久磁石式）部との間に隙間（エアーギャップ）が存在する。このエアーギャップにより磁束が著しく減少している。
In the case of a type having a stator core and a rotor core in the structure of the generator and motor, an iron core (iron core around which a coil is wound), an NS core (excitation type or permanent magnet type) part, There is a gap (air gap) between them. This air gap significantly reduces the magnetic flux.

磁束密度を減少させず維持させるには、エアーギャップを無くし直接接触させる方法が最も効果的である。そこで、ベアリングにより回転子コアと固定子コアを接触させる構造。
The most effective way to maintain the magnetic flux density without decreasing it is to eliminate the air gap and make direct contact. Therefore, a structure in which the rotor core and the stator core are brought into contact with each other by a bearing.

本発明は、鉄心コア部と、N.・Sコア部との隙間にベアリングを必要数バランス良く挿入し、ベアリング同士の軸を非磁性体にて連結固定するか、固定子コア又は、回転子コアにベアリングの軸を固定させることにより、点又は、線接触させ回転運動の円滑を図る構成とする。 The present invention inserts a bearing in a necessary balance in the gap between the iron core and the N.S core, and connects and fixes the shafts of the bearings with a nonmagnetic material, or the stator core or the rotor. By fixing the shaft of the bearing to the core, a point or line is brought into contact with each other so that the rotational motion is smooth.

磁束密度が、従来品より強化されるため，効率が上がり、軽量化及び、省スペース化が実現できる利点がある。 Since the magnetic flux density is strengthened compared with the conventional product, there is an advantage that efficiency can be improved, and weight saving and space saving can be realized.

ベアリングの設置間隔は、接触させ無いこと以外は、寸法、重量の規制内で設計でき、従来の電動機より高効率化が実現できる為、省スペース化を図ることが出来る。 The installation intervals of the bearings can be designed within the limits of dimensions and weight except that they are not brought into contact with each other, and can achieve higher efficiency than conventional motors, so that space can be saved.

Claims
