Ceiling fan with motor, blades, stator, and rotor
A recently granted patent (Publication Number: US11967883B2) discloses a ceiling fan design that includes a stationary motor shaft, a stator with stator windings, and a rotor with rotor laminations and a rotor cover. The rotor cover features a peripheral wall with blade mounts for attaching the set of blades. Additionally, the design incorporates end bells mounted on the rotor cover, a stationary motor shaft extending through the stator and end bells, and bearings coupling the end bell to the motor shaft. The blade mounts are circumferentially spaced and oriented at an angle relative to the rotational axis, enhancing the fan's efficiency and performance.
Furthermore, the patent describes variations of the ceiling fan design, including different materials for the rotor cover and rotor laminations, as well as the configuration of the blade mounts and ramps. The design also allows for direct mounting of the blades to the ramps without the need for an intervening blade iron. The patent emphasizes the unique features of the ceiling fan, such as the overcasting of the rotor cover onto the laminations and the specific orientation of the blade mounts, which contribute to the overall functionality and effectiveness of the fan. Overall, the patent showcases an innovative approach to ceiling fan design that aims to improve performance and efficiency while maintaining a sleek and functional aesthetic.
