摘要： 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.

摘要： A resolver includes an excitation coil for receiving an excitation signal formed by amplitude modulation of a high-frequency signal and a detection coil for outputting a detection signal. The resolver is arranged to detect a change in position of a rotor provided with the excitation coil or the detection coil based on the detection signal varying with the change in position of the rotor. The high-frequency signal is a digitized signal generated from a reference clock.

摘要： A resolver comprises an excitation coil for receiving an excitation signal and a detection coil for outputting a detection signal. The detection sine wave is changeable according to an amount of displacement of a movable element provided in the excitation coil or the detection coil. The resolver detects the amount of displacement of the movable element based on the excitation signal and the detection signal. The detection coil is one coil formed of a first detection coil pattern and a second detection coil pattern connected in series or in parallel such that the second detection coil pattern is shifted in phase by a half cycle from the first detection coil pattern.
