Claim:
1. A driving circuit for driving a reluctance motor, the reluctance motor including: a rotor; a stator; a first winding component having a number N of first phase winding portions that are wound around the stator, and that are electrically coupled in series to form a close loop having N first circuit nodes among the first phase winding portions, where N is an integer not smaller than 3 ; and a second winding component having N second phase winding portions that are wound around the stator, that respectively correspond to the first phase winding portions, and that are electrically coupled in a star configuration; for each corresponding pair of the first phase winding portions and the second phase winding portions, one of the first phase winding portion and the second phase winding portion being wound around the other of the first phase winding portion and the second phase winding portion, said driving circuit comprising: a capacitor battery unit having a positive terminal and a negative terminal to provide a direct current (DC) voltage therebetween; a switching circuit including: N damping capacitors respectively and electrically coupled to said second phase winding portions in parallel, to thereby form N resonant circuits that respectively correspond to said N first phase winding portions and that are electrically coupled to said capacitor battery unit.
