摘要： A motor arranged to rotate an impeller includes a rotor magnet fixed to a shaft, and a stator arranged opposite to the rotor magnet. The motor is arranged on an axially lower side of an impeller cup. The stator is fixed to an inner circumferential surface of a stator support portion. An opening-side end portion of the impeller cup is arranged opposite to an upper surface of the stator support portion. The upper surface of the stator support portion includes an expanded portion defined in a portion thereof which is opposed to the opening-side end portion of the impeller cup. The expanded portion is preferably located a greater distance from the opening-side end portion of the impeller cup than a distance between the opening-side end portion and a remaining portion of the upper surface of the stator support portion.

摘要： There is provided a drive device capable of driving a capacitive load with efficiency and with low power consumption while keeping quality input reproducibility for output signal. A switching drive circuit 10f repeatedly performs operations in the order of VCP charging phase PH_VCP_CH, VCP discharging phase PH_VCP_dCH, VCN charging phase PH_VCN_CH, and VCN discharging phase PH_VCN_dCH. A switching amplifier 10 allows a charging phase per cycle for an input signal VIN that is a reference for operation to be either a phase in which the slope of the input signal VIN is positive from a reference voltage REFL or greater until a maximum voltage, or a phase in which the slope of the input signal VIN is negative from a reference voltage REFH or less until a minimum voltage.
