Fan with improved electric motor and mounting |
摘要 |
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.
