A blower motor housing for a fuel burner has a generally "cup" shaped configuration with an open end that communicates with an opening in a side wall of a burner housing. The motor housing is mounted to the burner housing with the open end in register with the opening in the burner housing, thereby joining the interior of the motor housing with the interior of the burner housing. The electric motor is mounted within the motor housing with at least a portion of the stator winding extending axially beyond the open end of the motor housing and into the interior of the burner housing. A squirrel cage blower wheel is mounted to the motor shaft substantially concentric with the stator winding and extends at least partially along the axial length of the stator winding so that, during operation of the burner, cool intake air is moved past the stator winding as it is drawn into the blower wheel.
