MAGNETIC POSITION DETECTOR

摘要

PROBLEM TO BE SOLVED: To suppress magnetic interference occurring between the detecting parts when using a plurality of detecting parts having an exciting coil and a detecting coil to detect a position of an object. SOLUTION: A magnetic position detector comprises resolvers 34 and 36 which excite an exciting coil 46 using a exciting signal having a predetermined frequency and detects a position of a rotating member 20 based on an electromotive signal generated by detecting coils 48 and 50 due to a magnetic force of the exciting coil 46 wherein the predetermined frequencies of the exciting signals for the resolvers 34 and 36 are set to have different values.
