摘要： A magnetic pole position detecting device correctly acquires magnetic pole position even if two magnetic sensors are arranged at an arbitrary interval. The magnetic pole position detecting device receives the input of sensor outputs “a” and “b” of two magnetic sensors arranged at a predetermined interval L along a magnetic pole arraying direction and a phase difference φ between the two sensor outputs “a” and “b”. When sin φ>δ, the magnetic pole position detecting device divides a·sin φ by b−a·cos φ to calculate tan θ and outputs a magnetic pole position θ=tan−1 {a·sin φ/(b−a·cos φ)}. When sin φ≦δ, because a=sin θ and b=cos(θ+φ), the magnetic pole position detecting device outputs magnetic pole position θ={sin−1(a)+sin−1(b)−φ}/2. Because φ=2π×L/(a magnetic pole pitch or the number of poles), by using φ as a correction coefficient for the two sensor outputs “a” and “b”, magnetic pole position error can be canceled even when the interval L is different from a theoretical value.
