<P>PROBLEM TO BE SOLVED: To shorten the axial length of a motor shaft, and to improve an angle detection accuracy of a rotation detector (resolver). <P>SOLUTION: Casings 11, 20 of a motor structure with the resolver include a stator 12, the motor shaft 13 rotatably supported by a bearing 21, a rotor 15 integrally rotatable with the motor shaft 13, and a resolver for detecting a rotation angle of the rotor 15. The resolver includes a disc resolver stator 23 held on the casing 20 and having a surface on which a thin film coil is formed, and a disc resolver rotor 19 provided on an end face of the rotor 15 and having a surface on which a thin film coil is formed. A part of the casing 20 holding the outer periphery of the resolver stator 23 is formed as a shield portion 20b cylindrically protruding along the outer periphery of the resolver rotor 19 to the resolver rotor 19. The casing 20 and the shield portion 20b are each made of a non-magnetic conductive material. <P>COPYRIGHT: (C)2010,JPO&INPIT |
