摘要： An apparatus is provided for forming an axial flux permanent magnet synchronous motor. The apparatus includes a stator assembly including a plurality of stator poles spaced about a stator shaft, each comprising a winding. Adjacent pairs of stator poles have a spacing in a circumferential direction approximately equal to or greater than a width of the stator pole. A rotor assembly includes a plurality of rotor poles of alternating magnetic polarity arranged for electrically communicating with the windings of the stator assembly. The ratio of stator poles to rotor poles may be less than 4:6 or, more specifically, less than or equal to about 1:2.

摘要： A fan includes a hub, several fan blades, and a motor that is operable to drive the hub. A motor controller is in communication with the motor, and is configured to select the rate of rotation at which the motor drives the hub. The fan is installed in a place having a floor and a ceiling. An upper temperature sensor is positioned near the ceiling. A lower temperature sensor is positioned near the floor. The temperature sensors communicate with the motor controller, which includes a processor configured to compare substantially contemporaneous temperature readings from the upper and lower temperature sensors. The motor controller is thus configured to automatically control the fan motor to minimize the differences between substantially contemporaneous temperature readings from the upper and lower temperature sensors. The fan system may thus substantially destratify air in an environment, to provide a substantially uniform temperature distribution within the environment.

摘要： A fan includes a motor, a rotatable hub coupled to the motor, and at least one fan blade. The at least one fan blade includes a first end coupled to the rotatable hub, a second end, a leading edge, a trailing edge, a passage extending from the first end to the second end, and a winglet attached to the second end. At least one flexible strap extends through the passage of the at least one fan blade. The flexible strap is coupled at a first end to the rotatable hub and coupled at a second end to the winglet, such as to an inner portion thereof within the passage.

摘要： A system for mounting a fan to a ceiling includes a connector adapted to attach to the ceiling. The connector includes at least one guide. An adaptor is adapted to attach the fan to the connector, and includes at least one rail adapted for being received within the at least one guide. A safety bracket is also provided, which is adapted to attach to the ceiling separate from the connector and connect to a safety cable without using a tool. A motor support is also provided with a cavity adapted to receive the power supply, and at least one retainer serves to retain the power supply within the cavity. A quick-connecting escutcheon is also adapted to rotatably connect to the connector.

摘要： An apparatus includes a fan and a controller configured for controlling the fan to operate in a first mode limiting rotational speed of the fan within a first range of speeds between a first minimum speed and a first maximum speed. The controller is further configured to control the fan to operate in a second mode limiting rotational speed of the fan within a second range of speeds between a second minimum speed and a second maximum speed. The second range of speeds may be narrower than the first range of speeds. Related methods are also disclosed.

摘要： A fan includes a motor adapted to be rotated about an axis and a hub adapted to be rotated by the motor. The hub may include first and second hub parts adapted to mate to form the hub, the first and second hub parts having a gap therebetween. A plurality of fan blades each includes an end portion located in the gap formed between the first and second hub parts, which may be drawn together by a fastener to capture the blades therebetween. One or more of the fan blades may include a receiver, such as an open-ended groove, for receiving a portion of the hub. An adapter may be configured to remain stationary during use while the hub and fan blades rotate, and a portion of the hub is adapted to be selectively deployed to engage the adapter to prevent rotation of the hub. Related methods are also disclosed.

摘要： An apparatus for connecting one or more guy wires to a down rod, the connector having first and second separable portions which form an aperture for receiving the down rod. At least one of the first or second portions includes at least one passage adapted for releasably receiving a portion of the guy wire. The guy wire may include an anchor, and the passage for receiving the guy wire may be adapted for capturing the anchor so as to preclude movement of the guy wire in a radial direction.
