ABSTRACT:
A sensorless and brushless DC motor in which phase-corresponding coils are turned on at an electric angle of 180.degree..
The driving circuit of the DC motor includes comparators for outputting position detection signals, comparators for outputting turn-on signals, power transistors for turning on phase-corresponding coils, a rotation direction control section, a charge/discharge control section, a charge/discharge section, a turn-off signal generating section, and transistors for forcedly turning off the power transistors.
