Abstract
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.
