PROBLEM TO BE SOLVED: To improve stability and reliability in controlling, by outputting predetermined ON/OFF conditions corresponding to the ON/OFF conditions of a plurality of switching elements predetermined according to the conditions of a corrected position detection signal, and the condition of a rotor position detection signal at that time after overlapped energization elapsed time. SOLUTION: An ON/OFF signal generation means 6 for switching elements 8 outputs the first conditions of the ON and OFF of a plurality of switching elements 8, which are predetermined so as to conduct energization sequentially to a plurality of stator windings in each prescribed direction and order corresponding to the condition of a position detection signal corrected by a position detection correcting means 5, and outputs the second conditions of the ON and OFF of the switching elements 8 predetermined according to the condition of the position detection signal corrected by the position detection correcting means 5 after energization overlapping elapsed time. As a result, the generation of errors included in the output timing of the ON/OFF combination of the switching elements 8 is reduced, and the inequality of the overlapped energization time is reduced, thus it is possible to ensure stability in controlling. |
