Abstract
Rotating unit including a shaft, a blower rotor, and a motor armature is removable as a unit from the motor housing. The diameter of a first resiliently mounted bearing holder toward the blower rotor is larger than the diameter of the armature, which in turn is larger than the diameter of a second resiliently mounted bearing holder remote from the blower rotor.
