摘要： A pressurised gases source is provided, the source comprising a centrifugal impeller driven by a motor within a housing, the housing having a gases inlet, a gases outlet and a partition to define first and second interior regions. The first region is defined by the housing and the partition and comprises the gases inlet and the impeller, and the second region is defined by the housing and the partition and comprises the gases outlet. The first and second regions are fluidly connected by a crescent shaped opening formed in or by the partition.

摘要： A blower device (1) includes the following elements. An impeller (10) rotates around a central axis. A motor (20) includes a stator (24) and rotates the impeller (10) positioned above the motor (20). A motor housing (21) houses the stator (24). A fan casing (2) forms a first flow passage. An upper side of the fan casing (2) covers the impeller (10) and has a suction inlet (3). A lower side of the fan casing (2) has an evacuate outlet (4) communicating with the suction inlet (3) via the first flow passage. A flow inlet (21a) is provided in the motor housing (21) farther downward than a top surface of the stator (24). The flow inlet (21a) communicates with the first flow passage. The motor housing (21) has a second flow passage extending upward from the flow inlet (21a) and communicating with a space farther upward than the stator (24).

摘要： A fan device (1) includes an impeller (10) rotating around a central axis and a motor (20) disposed farther downward than the impeller (10). The impeller (10) includes a base unit (11) enlarged downward and plural blades (12) disposed on a peripheral surface of the base unit (11). Upper portions of the blades (12) are positioned at a leading end of a rotating direction with respect to lower portions. In an outer end portion on a front surface of each blade (12) at the leading end of the rotating direction, a radial-direction component of a normal unit vector of an upper end portion of the blade (12) is smaller than that of a lower end portion, assuming that an outer peripheral side of the blade (12) is a positive direction. A thickness of a root of the lower end portion is larger than that of the upper end portion.

摘要： An axial fan has an inner-rotor motor which includes a drive end, a non-drive end and a shaft which extends axially from the drive end; and an impeller which includes a cylindrical impeller cup and a number of impeller blades that extend radially from the impeller cup. The impeller cup has an open upstream end and a closed downstream end which is connected to the shaft. In operation, the motor spins the impeller to generate an airflow in a direction from the non-drive end of the motor to the drive end of the motor. The impeller cup is configured to receive the motor therein and surround the drive end of the motor but not the non-drive end of the motor. As a result, the non-drive end of the motor is exposed to the airflow during operation of the fan.
