Abstract: In a synchronous reluctance motor having a rotor having a plurality of pairs of an outer side slot formed at an outer periphery side and an inner side slot formed at inner side of the rotor. The distance between the outer periphery of the rotor and the outer side slot is determined to be the width of the stator magnetic pole portion of the stator multiplied by 0.7 to 1.3. A first total magnetic flux amount of an outer side permanent magnet disposed in the outer side slot is determined to be larger than or equal to a second total magnetic flux amount of an inner side permanent magnet disposed in the inner side slot.

Abstract: Flexural rigidity E of a target wire harness (to be referred to as a WH hereinafter) is calculated by a predetermined bi-quadratic function associated with a curvature &rgr; on the basis of a diameter &phgr; of the WH, and the wiring shape of the WH which satisfy fixing positions is calculated on the basis of torsional rigidity C and the weight per unit length which are supplied from a storage device in accordance with the diameter &phgr; of the target WH (S4-S5). The bi-quadratic function is set such that the calculated flexural rigidity E decreases as the curvature &rgr; of the WH increases.

Abstract: A switched reluctance motor is provided with multi-phase coils on the stator poles. An energization on angle, a first energization off angle, a second energization off angle and a target value corresponding to an angle of rotation are determined with respect to each coil on the basis of a target torque and a rotation speed. A pair of transistors which act as switching elements are both turned on when the angle of rotation is reached at the energization on angle. One transistor is turned off if a value of an actual current is target value of the current while the angle of rotation is not reached at the first energization off angle. The same transistor is turned off irrespective of the magnitude of the value of the actual current and the target value of the current when the angle of rotation is reached at the first energization off angle. The transistors are both turned off when the angle of rotation is reached at the second energization off angle.
