摘要： A mixed-flow fan features a housing (42); an impeller (43) journaled rotatably with respect to the housing, and equipped with fan blades (54); a generally cylindrical air conduit (50) defined between the fan housing and the impeller, the fan blades extending into the air conduit in order, during operation, to transport air; an external-rotor motor (75) having an internal stator (100) and an external rotor (74) which includes a tubular ferromagnetic yoke (63) partly embedded in material of the impeller. A cup-shaped yoke (72) fits into a central cavity (68) of the tubular yoke (63) and accommodates a permanent magnet arrangement (66) which interacts with the stator. The tubular yoke (63) and the cup-shaped yoke (72) together serve as a magnetic return path for the external-rotor motor. The structure minimizes damage during final assembly, and simplifies insertion of balancing weights.

摘要： An impeller and at least a portion of a cooperating peripheral volute may be integrated are integrally injection molded with, concentric outer rotor and inner stator assemblies, respectively, to achieve a low profile precision impeller mechanism based on an improved brushless D.C. motor with low length to diameter ratio and suitable for use in a variety of other applications. A rotating cap has an inner circumference which is molded about an outer ferromagnetic back ring that in turn supports a rotor magnet having a number of poles of alternating polarity and separated by a relatively small cylindrical air gap from a fixed stator assembly. The fixed stator assembly is integrally molded into a base housing having a bearing support that extends upwardly through the center of the stator assembly and that is rotatably coupled to a rotating shaft that extends downwardly from the center of the rotating cap.

摘要： An electronic device having a first motor which rotates a rotating body (for example, blades) about a rotation axis and a second motor which vibrates a vibrator including the rotating body in the axial direction is provided. A control IC unit has a first circuit which subjects the rotation to control drive by a first waveform, and a second circuit which subjects the vibration to control drive by a second waveform. Rotation and vibration of a rotating and vibrating unit driven by the first and second motors generates an airflow and output sound by a synthesized output of a first output corresponding to the rotation and a second output corresponding to the vibration. The control IC unit generates a second waveform by using a reversed-phase waveform with respect to the first waveform or the like and suppresses the output sound by control of the first and second waveforms.
