Inductive drive angle position sensor measurement error detection procedure sends sine and cosine output signals to processor for trigonometric comparison

摘要

An inductive drive (14) angle position sensor (12) measurement error detection procedure digitises the sine (16) and cosine (18) outputs and sends them redundantly by a bus (22, 24) to a reliable technology processor (20) serving several drives that checks their trigonometric relationship by calculation or table interpolation.
