摘要： A motor driving device includes (a) a wide-angle feeding device for feeding power to three-phase coils in a width of 150 degrees in electrical angles and (b) a feeding amount controller for controlling a feeding amount to the coils. During overlapping periods, in which adjacent coils out of the three coils are in the same fed condition, an amount of a first value is fed to the coils and an amount of a second value is fed during the periods other than the overlapping periods. This structure allows the motor to reduce torque ripples, vibrations as well as noises during its operation, and at the same time, the motor can produce a greater output and operate at higher efficiency.

摘要： A motor driving power supplying section obtains an output voltage by switching-controlling a predetermined voltage outputted from a main power supply and smoothing a voltage thus switching-controlled. A driving transistor group includes a plurality of driving transistors, for supplying electric power based on the output voltage of the motor driving power supplying section to the motor driving coils of multiple phases. A commutation control section supplies conduction switching signals to the driving transistor group so as to switch successive conduction states of the motor driving coils. An output control section controls the output voltage of the motor driving power supplying section so that a collector-emitter voltage of at least one of the plurality of driving transistors included in the driving transistor group has a predetermined value. A torque control section controls conduction current intensity to the motor driving coils by controlling output currents of the plurality of driving transistors included in the driving transistor group.
