PROBLEM TO BE SOLVED: To provide a drive circuit for attaining an inexpensive SR motor with low noise. SOLUTION: In the drive circuit of an SR motor which is constituted with both ends of a stator coil 5 connected between the middle connection point between a switch element 1 and a diode 3 and that between a diode 4 and a switch element 2, a series circuit of a capacitor 7 and a resistor 8 and that of a resistor 9 are connected between both the terminals of the switch element 1 in parallel, as well as a similar circuit is also provided in the switching element 2. Also, a diode 6 for preventing vibrating current is connected to the stator coil 5 in series. |
