Abstract:
A motor driving circuit for controlling driving currents to be supplied to stator coils of a plurality of phases so as to supply the driving currents to said stator coils in sequence so as to generate a rotating magnetic field, the interaction between the rotating magnetic field generated by said stator coils and a magnetic field generated by a magnet of a rotor causing said rotor to rotate with respect to said stator coils comprising:driving means for supplying the driving currents to said stator coils, respectively; andpreventing means for preventing said driving means from supplying the driving currents to said stator coils in sequence, said preventing means comprising a leakage absorbing circuit for detecting a plurality of time periods during which a plurality of transistors should be in their turned off states, respectively, and turning off said plurality of transistors during said plurality of time periods, respectively.
