    • A casing of a motor with resolver includes a stator, a motor shaft rotatably supported by a bearing, a motor rotor integrally rotatable with the motor shaft, and a resolver for detecting a rotation angle of the motor rotor. The resolver includes a disc-shaped resolver stator held on the motor casing and having a surface on which a thin-film-shaped coil is formed, and a disc-shaped resolver rotor provided on an end face of the motor rotor and having a surface on which a thin-film-shaped coil is formed. Part of the motor casing holding the outer periphery of the resolver stator is formed as a shield portion cylindrically protruding along the outer periphery of the resolver rotor to the rotor. The motor casing and the shield portion are each made of a non-magnetic conductive material.
    • 具有旋转变压器的电动机的壳体包括定子,由轴承可旋转地支撑的电动机轴,与电动机轴一体旋转的电动机转子,以及用于检测电动机转子的旋转角度的旋转变压器。 旋转变压器包括保持在电动机壳体上并具有形成有薄膜状线圈的表面的盘形分解器定子,以及设置在电机转子的端面上的具有表面的圆盘形旋转变压器转子 其上形成有薄膜状线圈。 保持分解器定子的外周的马达壳体的一部分形成为沿着旋转变压器转子的外周向圆筒状突出的保护部。 电动机壳体和屏蔽部分均由非磁性导电材料制成。
