摘要： An influence resulting from double saliency of an electric motor, i.e., an influence of a deviation of the axis of an alternating current due to a rotor magnetic pole position θ on the estimation of a magnetic pole position, is eliminated, and, in particular, the magnetic pole position of double saliency electric motor can be estimated with high precision. To this end, an alternating voltage impression section impresses an alternating voltage on an electric motor, a current detection section detects a motor current, a reference direction generation section outputs an instantaneous reference direction θ′ from a rotor magnetic pole position θ of the electric motor, a vector conversion section separates the detected current into a parallel component and a quadrature component with respect to the reference direction θ′, and a magnetic pole position estimation section estimates actual rotor magnetic pole position θ of the electric motor based on at least one of the parallel component and the quadrature component of the current.
