摘要： The invention has an object to provide a magnetic pole position estimating method and a control apparatus for a synchronous motor which reliably detect the position of a magnetic pole of the synchronous motor to carry out stable control also when a high load is applied or a load is suddenly changed.

A high-frequency impedance estimator (10) estimates high-frequency impedances Zdm and Zqm on two points which are advanced and delayed by an electrical angle of 45 degrees from a &ggr;-axis. A first magnetic pole position estimator (13) estimates a first magnetic pole position estimated value &thgr;{circumflex over ( )} to eliminate a deviation between the high-frequency impedances Zdm and Zqm. A second magnetic pole position estimator (14) inputs a current command value i&dgr;* to estimate an internal phase angle compensating angle &thgr;{circumflex over ( )}r and subtracts the internal phase angle compensating angle &thgr;{circumflex over ( )}r from the first magnetic pole position estimated value &thgr;{circumflex over ( )}, and outputs a second magnetic pole position &thgr;{circumflex over ( )}c.
