ABSTRACT:
A blower unit which, in one embodiment, includes an elongate main mounting member, a stator, a fan subassembly, and a blower housing, is described. In the one embodiment, the elongate main mounting member is the main structural member of the unit. The stator includes a stator core and stator windings, and the stator is secured to the main mounting member. The fan subassembly includes a rotor and a plurality of vanes. The rotor includes a substantially cylindrical iron ring and a magnetic portion having a substantially cylindrical shape. The magnetic portion is secured within the inner diameter of the iron ring and defines a rotor bore. The stator is located in the rotor bore and is concentric with respect to the rotor. The rotor is coupled to the plurality of vanes so that the vanes rotate with the rotor. The fan subassembly also includes bearing assemblies which are spring biased toward, and into rotatable engagement with, the elongate main mounting member. The fan assembly further includes a shroud for partially enclosing the plurality of vanes.
