PROBLEM TO BE SOLVED: To obtain a highly-accurate digital resolver signal by equalizing each amplitude of two-phase resolver signals outputted from a resolver.SOLUTION: An amplitude automatic adjustment method of a resolver signal is a method for equalizing each amplitude (2A', 2B') of each resolver signal (A'sin&thetas;, B'cos&thetas;) by multiplying each resolver signal (A'sin&thetas;, B'cos&thetas;) by each amplitude (2A', 2B') of two-phase resolver signals (A'sin&thetas;, B'cos&thetas;) in an A/D converter (3).SELECTED DRAWING: Figure 1 |
