PROBLEM TO BE SOLVED: To avoid overcurrents and to generate power with high efficiency. SOLUTION: This method is for controlling an SR motor, which has a stator with a plurality of salient poles, a rotor with a plurality of salient poles whose number is different from the number of the salient poles of the stator and windings wound on the stator. While a supply mode, where a power from a battery is supplied to the windings, is carried out (ST1), various values including the revolutions of the rotor are detected (ST2). Maximum current values, which are applied to the windings when it is supposed that the changeover to a regeneration mode where electromotive forces generated in the windings, are regenerated by a battery is carried out at present are successively calculated for estimation (ST3). When the maximum current value reaches a prescribed value (ST4), the changeover to the regeneration mode is carried out (ST5). |
