Abstract: A fan assembly is disclosed. The fan assembly has a frame and a motorized blade assembly. The motorized blade assembly has an electric motor and an integrally attached bladed propeller with a central hub. The motor includes a rotor and a stator, the rotor having a rotatable output shaft extending from a front side of the motor with a bladed propeller secured to the output shaft. The motor includes a housing with a mounting area for securing an electrical control switch. The mounting area is provided by a flange portion of the rear motor wall and positioned radially outwardly relative to the output shaft, and provides mounting of the control switch with a user interface that is exposed from the fan frame. The fan assembly motor also may provide an electrical connection port for removable attachment of an electrical power cord, wherein the connection port is integral with the motor housing and is exposed from the fan frame for attachment of the cord by a user.

Abstract: An apparatus and method for assembling a fan grill to a shroud of a fan housing. The apparatus includes a support structure having a moveable carriage disposed in a horizontal plane. The moveable carriage is adapted to align and carry the fan grill and shroud combination. A clamping structure is moveably attached to the support structure and has clamps adapted to clamp the fan grill and shroud combination in a fixed position. A plurality of automatic drivers attached to the clamping structure are moveable in a direction transverse to the horizontal plane of the carriage. The automatic drivers drive a plurality of fasteners into the fan grill and shroud combination. The moveable carriage may be adapted to carry more than one fan grill and shroud combination to allow an operator to load a second fan grill and shroud combination onto the carriage while a first fan grill and shroud combination is engaged by the drivers.

Abstract: A household fan with motor and motor housing for shielding the motor. The electric motor is preferably a four-pole permanent-split capacitor motor with a narrow profile enabling it to fit within a narrow box fan, the motor having a stator including a core of stacked laminations. A first outermost lamination defines a first supporting surface, and a second outermost lamination defines a second supporting surface on which the front and rear casings are supported. Copper windings are wound about the core. A rotor has an output shaft which passes through a central region of the core. The front and rear casings are generally dome-shaped. Each casing has a circumferential side wall and a vented end wall. The front casing has a recessed area around the opening for the output shaft such that a portion of the bladed propeller assembly protrudes within the recessed area, allowing for a narrow profile design. Radially extending legs allow for mounting on parallel brackets along a rear grill of the fan.
