Abstract: A rotating electric machine has a drive control part and a motor having a stator and a rotor. The drive control part has an external disturbance voltage instruction generation part, a switching signal generation part, first and second drive circuits, a current acquisition part detecting an external disturbance current flowing in three phase winding in each of a first coil and a second coil of the stator, and a phase angle estimation part detecting a phase angle of the rotor of the motor based on the detected external disturbance current. The drive control part adjusts turn-on/turn-off timings of switching signals so as to reduce a timing difference between corresponding line external disturbance voltages in the three phase windings more than the time difference without performing the timing adjustment while maintaining a duty ratio of these line external disturbance voltages to that when the timing adjustment is not performed.

Abstract: When a start condition is satisfied after the internal combustion engine has been stopped according to an automatic stop control, a control apparatus reversely rotates the engine to compress an air in an expansion stroke cylinder at that time point, and thereafter generates a first time combustion.
