Abstract
An electric fan includes a plurality of blades and an electric motor for rotating the blades. The electric motor includes a stator and a rotor rotatable relative to the stator about an axis. The rotor includes a backing ring and a diecast rotor can. The can includes a non-machined sidewall that is diecast integrally as part of the rotor can. The sidewall extends about the axis. The rotor can is diecast in an overlying relationship with at least part of the backing ring, with the sidewall and backing ring being securely interengaged so as to restrict relative shifting therebetween.
