Abstract
A direct drive, high velocity, high power centrifugal air blower. The blower employs a high-speed electric motor (>15,000 rpm) having an output drive shaft that is directly coupled to an impeller rotatably housed within a volute. The assembly enables the impeller to rotate at speeds up to 100,000 rpm without the need for either step-up gears or belts and pulleys interposed between the motor output drive shaft and the impeller. The elimination of an indirect coupling assembly between the motor ouput shaft and the impeller provides a high power, high velocity blower/vacuum with greater reliability than indirectly coupled assemblies.
Claims2
A centrifugal fan consisting essentially of:
- (a) an electric motor operable for rotating a drive shaft at rotational velocities greater than 15,000 rotations per minute;
- (b) an impeller affixed to said drive shaft;
- and (c) a volute substantially enclosing said impeller, said volute having an axially disposed air intake port and a tangentially disposed air output port.
