<P>PROBLEM TO BE SOLVED: To provide an electric drive unit of high performance, with which an error included in output information of a magnetic pole position sensor incorporated in an electric machine device is reduced and ripple torque of the electric machine device, which occurs by influence of the error, can be suppressed. <P>SOLUTION: The electric drive unit is provided with a sensor output correcting circuit 15 correcting output information of the magnetic pole position sensor 11 incorporated in a permanent magnet rotating electric machine 1. Position sensor output correction information for correcting output information of the magnetic pole position sensor 11 is obtained in accordance with output information of a current sensor 13. Output information of the magnetic pole position sensor is corrected in accordance with position sensor output correction information. Output information of the magnetic pole position sensor after correction is outputted to an invertor device as position sensor correction output information. <P>COPYRIGHT: (C)2008,JPO&INPIT |
