Abstract

The domestic fan has an axially bladed rotor (7) has a snap-on coupling (3) for connecting the rotor to the stub shaft (1) of the electric motor (2). The coupling (3) is a sheet metal stamping having a base (4) securable to the shaft (1), and having axially prejecting arms (5) engageable by a snap-on action with holes in an end glange of the plastics moulded rotor. The flange has a boss projecting between the arms and engaging the end of the shaft to centralise the rotor. The axial arms are stamped and bent from a disc-shaped blank whose remaining radial portions form surfaces (2) for dissipating heat from the shaft.
