Description
互いに同軸に且つ磁気干渉を起こしうるほど近接して配置され、軸倍角が同一の2つのレゾルバと、
それぞれのレゾルバから出力される出力信号を処理して、回転体の回転角情報を出力する信号処理部とを備え、
前記信号処理部が、それぞれのレゾルバに基づく回転体の回転角を表す信号の平均値を求めて、回転体の回転角情報を生成することを特徴とする。
θ=1/N・tan−1(ESIN−GND/ECOS−GND)
ここで、ECOS−GNDは、cos相の出力電圧を表し、ESIN−GNDは、sin相の出力電圧を表す。以下では、R/D106から出力される出力信号を、「φ1」で表し、R/D103から出力される出力信号を、「φ2」で表す。
102,104、202,204、302,304 レゾルバ
106,108 R/D
110,210 信号処理部
220 断線検知部
222 逆オフセット印加部
