    摘要: A control device for a brushless motor capable of stopping the brushless motor without any complicated control. The control device includes a rotation control section to which an output of a position detector detecting a polarity of a magnet field of a rotor on a side of a stator is fed and which generates a driving signal of a predetermined polarity based on the output of the position detector input thereto. Also it includes a motor driving section to which the driving signal is fed and which flows an excitation current through a driving coil for a phase determined depending on a polarity of the driving signal input thereto. The rotation control section includes a latch circuit which feeds the motor driving section with a signal of a polarity corresponding to that of an output signal of the position detector while it is fed with a rotation command and holds, when it is fed with a stop command, the signal fed to the motor driving section at a polarity thereof obtained at the time of feeding of the stop command thereto.
