RESOLVER, AND METHOD FOR ADJUSTING POSITION OF SHAFT CENTER OF ITS STATOR, STATOR COIL POSITION ADJUSTING METHOD, AND ABSOLUTE PRECISION MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for highly precisely correcting deviations of the shaft center of a resolver stator.;SOLUTION: In the method for adjusting the position of the shaft center of the stator (32) of a single-pole resolver (30) in which a fundamental wave component of the reluctance of a gap between a rotor (31) and the stator (32) forms one period by one rotation of the rotor (31), a rotor (35) for shaft center adjustment in which a plurality of teeth (36) are arranged at regular intervals in the circumference is concentrically arranged with the stator (32) instead of the rotor (31). Then by rotating the rotor (35) for shaft center adjustment, resolver signals outputted from stator coils (C₁-C₁₈) wound on the stator (32) are converted into two-phase signals. The position of the shaft center of the stator (32) is adjusted on the basis of a waveform acquired by inputting the two-phase signals to an oscilloscope.;COPYRIGHT: (C)2006,JPO&NCIPI
