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