WIPO Patent Application WO/2022/145035
Kind Code:
A1
Abstract:
In the present invention, an armature unit has a first armature core (H1), a second armature core (H2), and a core linking part (L) magnetically coupling the first armature core (H1) and the second armature core (H2). The first armature core (H1) has magnetic pole sets (G1u, G1v) which are magnetically coupled. The second armature core (H2) has magnetic pole sets (G2u, G2v) which are magnetically coupled. A first magnetic flux (Φ1) and a second magnetic flux (Φ7) are formed in the armature unit by magnets (Mg). A first magnetic circuit through which the first magnetic flux (Φ1) flows includes the magnetic pole set (G1u), the magnetic pole set (G1v), the magnetic pole set (G2u), the magnetic pole set (G2v), field cores (22N, 22S), and the magnets (Mg). A second magnetic circuit through which the second magnetic flux (Φ7) flows includes the magnetic pole set (G1u), the core linking structure, the magnetic pole set (G2u), the field cores (22N, 22S), and the magnets (Mg). The foregoing configuration makes it possible to suppress magnetic saturation of the magnetic circuits formed in the armature unit, and also eliminates the necessity of magnetically dividing each armature core in the machine actuation direction, which makes it possible to increase the strength of the armature core.
