The control device of the alternative rotating electrical machine is configured as follows. a d-axis current command value and a q-axis current command value are kept at zero in dq vector control, in the state where the alternative rotating electrical machine is rotating. A time during which the output of the middle point level judging means is Hi is counted. A duty is calculated out from the ratio with a carrier wave cycle, and a conversion is conducted into a two-axis rotating coordinate system (three-phase to two-phase conversion) from the calculated out duty and the magnetic pole position, to calculate out a two-phase signal. The magnetic pole position origin point correction amount is calculated out based on a predetermined operation equation, from the two-phase signal. A magnetic pole position origin point correction is performed based on the calculated out magnetic pole position correction amount.
