Abstract

　磁気式エンコーダ（１０）の多極マグネット（２１）を備えた多極側磁気検出部（１１）では、９０°の位相差の正弦波信号を出力する第１、第２磁気検出素子（Ａ１、Ｂ１）と、第３、第４磁気検出素子（Ａ２、Ｂ２）とが、機械角で１８０°離れた角度位置に配置されている。第１、第３磁気検出素子（Ａ１、Ａ２）は電気角で同一位置に配置され、同相の正弦波信号を出力し、第２、第４磁気検出素子（Ｂ１、Ｂ２）は電気角で同一位置に配置され、同相の正弦波信号を出力する。第１、３磁気検出素子（Ａ１、Ａ２）の出力信号の和信号を取り、第２、４磁気検出素子（Ｂ１、Ｂ２）の出力信号の和信号を取ることにより、２極マグネット（２２）からの磁束に起因する第１～第４磁気検出素子（Ａ１～Ｂ２）の検出信号の誤差成分、多極マグネット（２１）の回転振れに起因する検出信号の誤差成分を除去あるいは大幅に抑制でき、回転角度を精度良く検出できる。
