Zusammenfassung:PROBLEM TO BE SOLVED: To restrain a circuit architecture and an interfering pulse properly. SOLUTION: Power voltage or DC voltage Uo equivalent to the voltage, reference voltage, and a triangular waveform lamp voltage Ur are supplied. The three voltages are delivered to switching means 4, 5, 6. A controller P controls the switching means, and the switching means periodically conducts switching between the voltages Uo, Ur and the reference voltage. As a result, periodical trapezoidal waveform control signals (c), (d), (e) are formed. The periodical trapezoidal waveform control signals (c), (d), (e) drive wiring divisions 1, 2, 3 corresponding to the motor 10.
