摘要:
An ceiling fan (10) comprising a motor system (16). The motor system (16) is mounted around a motor shaft (90). The motor shaft (90) couples to a downrod (14) for suspending the ceiling fan (10) from a structure. The motor shaft (90) and motor (16) are encased by a motor housing (198). The motor housing (198) comprises hub arms (202) for mounting a plurality of blade holders (18). The blade holders (18) coupled to a plurality of blades (20) rotatable about the motor (16) during operation. The downrod (14) comprises a wire disk (58) mounting guy wiring (22) to the downrod (14). A retention rod (304) is utilized internal of the motor (16) and downrod (14) as a secondary retention method. An electrical connector (568) is internal of the motor shaft (90) and electrically couples to the stator to power the motor (16).

Ein elektronisch kommutierter Außenläufermotor (20) hat einen Innenstator (162); einen glockenartigen Außenrotor (22) mit einer Rotorglocke (26), welcher Außenrotor (22) durch einen magnetisch wirksamen Luftspalt (168) vom Innenstator (162) getrennt ist, ein Lagerrohr (52), auf welchem der Innenstator (162) angeordnet ist und in dem eine dem Außenrotor (22) zugeordnete Welle (50) drehbar gelagert ist. Das Lagerrohr (52) hat einen rotornahen Abschnitt, der sich in axialer Richtung bis in den Bereich des Rotorbodens (43) erstreckt, und es hat einen rotorfernen Abschnitt, der sich in axialer Richtung vom rotornahen Abschnitt weg erstreckt. Am rotorfernen Abschnitt des Lagerrohres (52) ist ein Flansch (62) vorgesehen, und zwischen dem Flansch (62) und dem Rotor (22) ist ein Dichtelement (90) angeordnet, das mit mindestens einer Dichtlippe versehen ist und das Trockenlaufeigenschaften hat.
摘要:
An electronic pump includes a controller. The controller includes a power input terminal, a printed circuit board, a motor driver and a microprocessor. The power input terminal, the microprocessor and the motor driver are spaced from each other by an electronic clearance and are fixedly connected to the printed circuit board. The microprocessor is electrically connected to the motor driver by the printed circuit board. The motor driver drives a motor to rotate based on a drive control signal from the microprocessor. There is no motor drive circuit composed by discrete components and configured to drive the motor to rotate separately arranged on the printed circuit board between the motor driver and a motor. The setting of peripheral discrete components can be avoided and the energy consumption can be reduced with the application.

A fan plate system can include a fan plate and may or may not include the fan. The fan plate can include one or more surfaces. The fan plate can also include a grill configured to allow air to flow into or from a fan through the grill. The one or more surfaces can be configured to connect to a first end of an outer housing of the fan. The one or more surfaces can also provide a gap between the first end of the fan outer housing and the grill when the fan outer housing is connected to the fan plate. In some embodiments, an electronic device can include a fan plate system.
