摘要： Claw-shaped magnetic poles are alternately disposed along the rotation plane of a rotor of an electric rotating machine, and a permanent magnet is disposed between the claw-shaped magnetic poles. Surface of the permanent magnet is coated with a coating layer. The coating layer is composed of a anticorrosive material performing sacrificial anticorrosion (metal flake in a coating film rusts prior to a matrix resulting in protection of the matrix) such as inorganic material containing zinc and a film of the anticorrosive material is formed by spraying. Ionization tendency of zinc is larger than that of iron composing the permanent magnet, and the permanent magnet is difficult to be rusted owing to the sacrificial anticorrosion. Consequently, anticorrosion of the permanent magnet disposed between the claw-shaped magnetic poles is improved.
摘要翻译：爪形磁极沿旋转电机的转子的旋转平面交替布置，并且永磁体设置在爪形磁极之间。永磁体的表面涂覆有涂层。涂层由防腐蚀材料（包括在保护基体的基体之前在涂膜中生锈的金属薄片）如含锌的无机材料和防腐蚀材料的膜形成的防腐材料组成。锌的离子化趋势大于构成永磁体的铁的电离倾向，由于牺牲防腐蚀，永磁体难以生锈。因此，提高了设置在爪形磁极之间的永磁体的防腐蚀。
