摘要

The present invention relates to a stator magnetic flux estimating device for estimating an initial position of a rotor of a synchronous machine including the rotor and the stator. The stator magnetic flux estimating device comprises: an initial value setting part setting an initial value according to a state of line-to-line voltage in integrating an organic line-to-line voltage of the stator; a line-to-line voltage integrating part integrating the line-to-line voltage; and a negative feedback part negatively feedbacking an output value for noise reduction. The output value is a value adding an output value of the line-to-line voltage integrating part to a negative feedback value of the output value. The set initial value is added to the line-to-line voltage integrating value.
