Abstract
A compact air blower assembly operates efficiently at high speeds, such as 10,000 to 12,000 rpm, and can be inexpensively manufactured from a common set of blower parts to provide varied airflow capacities, and satisfy a variety of applications. The compact multi-use air blower assembly is provided by a high speed brushless electric motor comprising a stator and a rotor and rotatable shaft carried by a pair of shaft bearings, with the rotatable shaft including a shaft extension extending outwardly from one of the shaft bearings. A housing includes a first portion electric motor and shaft bearings and a second portion surrounding the first portion, forming a blower enclosure about the shaft extension with a centrally located air inlet and a peripherally located air outlet. The blower enclosure encompasses a centrifugal blower wheel including a solid wall extending radially outwardly from a shaft-engaging hub and forming a plurality of air-moving blades projecting axially outward from the wall to edge portions that extend radially within the blower enclosure between the air inlet and the air outlet.
