Title:
シンクロナスモーターおよびモーターアッセンブリ
Document Type and Number:
Japanese Patent JP6708858
Kind Code:
B2
Abstract:
A synchronous motor (10) is provided with: a rotor (11) which is rotatable around a rotating shaft (10A); a housing (13)(stator) disposed around the rotating shaft (10A); a first assembly (12)(first field magnet) which causes generation of a magnetic field (12D) in the rotor (11); a second assembly (14)(second field magnet) which is disposed around the rotating shaft (10A) in the housing (13) and causes generation of a magnetic field (14D) separately from the first assembly (12); and a third assembly (15)(exciting body) which causes generation of a varying magnetic field for providing the first assembly (12) with an angular momentum that causes rotation of the rotor (11). One of the magnetic field (12D) due to the first assembly (12) and the magnetic field (14D) due to the second assembly (14) has a magnetic field line (12E) in a direction along the circumference of the rotating shaft (10A), and the other has a magnetic field line (14E) in a direction along a moving radius direction toward the rotating shaft (10A).
