摘要： A motor driver includes a first signal selector and a second signal selector. The first signal selector is used for selecting a signal to be supplied to an energizing unit of driving coils, and selects either one of a normal energizing pattern signal supplied from an energizing signal generator or a signal from the second signal selector based on a signal from an over-current detector. The second signal selector selects either one of a first non-normal energizing pattern signal from a first energizing signal output unit or a second non-normal energizing pattern signal from a second energizing signal output unit based on a signal from a rotary direction detector.

摘要： In a motor driver, based on driving waveforms of respective phases generated by a driving waveform generator, a power feeder feeds respective phase-coils with an alternating current consecutively changing in sine wave. Further, a phase advancing controller adjusts phases of the driving waveform, and performs phase-advancing control such that each phase of back electromotive forces induced in respective phase-coils generally coincides with a phase of the ac running through the coils. In phase-advancing controlling, a phase current is detected with a common current. The structure discussed above can reduce torque ripples, vibrations and noises, and a motor thus can be driven efficiently.
