流フアンモータ。[Claims for Utility Model Registration] (1) A drive current control transistor switch provided for each phase to turn on and off the drive current of the stator coil of each phase of a brushless DC fan motor having a two-phase stator coil; In a drive circuit for a brushless DC fan motor comprising a drive control circuit that controls on/off transistor switches of each phase according to the position of a rotor of the motor, the drive current of each phase changes when a steady rotation command signal is given. A speed switching control circuit is provided which allows the control transistor switch to turn on and off and holds the drive current control transistor switch of any one phase in a cut-off state when a low speed rotation command signal is given. Brushless DC fan motor drive circuit. (2) The speed switching control circuit includes a cutoff control switch connected to the drive current control transistor switch of any one phase so as to cut off the drive current control transistor switch of any one phase when the transistor switch is turned on, and a steady rotation command signal. and a cutoff control switch control circuit that controls the cutoff control switch to be held in the cutoff body when a low speed rotation command signal is given, and to make the cutoff control switch conductive when a low speed rotation command signal is given. A brushless DC fan motor according to claim 1 of the utility model registration claim.
