METHOD FOR DETERMINING TWO PSEUDO-SINE-WAVE SIGNALS IN QUADRATURE PHASE

摘要

PROBLEM TO BE SOLVED: To regulate a signal by a detecting element for uniformity in a quadrature phase and an amplitude. SOLUTION: The present invention relates to a method for determining two pseudo-sine-wave signals in the quadrature phase, using the pseudo-sine-wave signal transmitted from an encoder 1. The method uses at least four detecting elements 3 arranged linearly and uniformly with respect to a detecting means 2 arranged in a reading distance of the encoder 1 and for transmitting a signal transmitted from the encoder 1, as a signal Si. In the method, the transmitted signals Siis measured, and the signals Siare combined to form a signal U and a signal V in the quadrature phase calculated by (S1-S2)-(S3-S4) and (S2-S3). The present invention relates to a determination system for carrying out the determination method, and a bearing provided with the determination system. COPYRIGHT: (C)2008,JPO&INPIT
