Patent number: 11867189Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. The motor is coupled with the hub by a hollow drive shaft, such that the drive system of the fan system is gearless. The motor is controlled by a PFC-based control module, which is in communication with sensors that are configured to sense parameters associated with operation of the fan system. The control module is configured to react in certain ways to certain conditions detected by the sensors, such that the fan system uses feedback-based control algorithms. A remote control panel is in communication with the control module. The remote control panel is operable to display fault conditions detected by the sensors. Blade retainers prevent fan blades from falling when a fan blade breaks free from the hub. Pins prevent the hub from falling when the hub breaks free from the rotor.Type: GrantFiled: March 1, 2022Date of Patent: January 9, 2024Assignee: DELTA T, LLCInventors: Richard A Oleson, J. Carey Smith, Richard W. Fizer, Richard M. Aynsley, Elios Klemo

Publication number: 20210180602Abstract: A fan system comprises a hub, a plurality of fan blades, a drive system, and a stationary tube. The hub is configured to rotate. The fan blades are mounted to the hub. The drive system comprises a rotatable hollow output shaft. The hollow output shaft is in communication with the hub, such that the drive system is operable to rotate the hub via the hollow output shaft. The stationary tube is inserted through the hollow output shaft. The stationary tube is configured to remain stationary as the hollow output shaft rotates. Wires and the like may be passed through the stationary tube, to reach an accessory mounted at the bottom of the stationary tube. The fan system may also include a detector, such as a heat detector, a smoke detector, or an accelerometer. The detector may power down the fan system in response to detecting certain conditions.Type: ApplicationFiled: February 26, 2021Publication date: June 17, 2021Inventors: Richard M.

Patent number: 10436033Abstract: A fan system includes a motor, a rotatable hub, and a plurality of fan blades. Each of the fan blades includes a substantially rigid spine member, a resilient leading edge member, and a resilient trailing edge member. The leading edge member and trailing edge members are removably coupled with the spine member, such that different leading edge members and different trailing edge members may be chosen to customize the leading and trailing edges of the fan blades. Each fan blade may have more than one type of leading edge member or more than one type of trailing edge member. The leading edge member and trailing edge member may each be coupled with the spine member by urging the leading edge member and trailing edge member in a direction that is substantially perpendicular to the longitudinal axis defined by the spine member.Type: GrantFiled: September 9, 2013Date of Patent: October 8, 2019Assignee: Delta T, LLCInventors: J.

Patent number: 10054131Abstract: A fan assembly comprises a hub and fan blades. The hub includes a plurality of sockets configured to receive complementary mounting blocks of the fan blades. The mounting blocks each include at least one tapered shoulder portion. The mounting blocks are each tapered along three dimensions. Each mounting block comprises a rear face seated against a complementary rear face of the corresponding socket and a front face that is exposed relative to the hub. A cap secures the fan blades to the hub. The fan assembly may also include one or more shrouds positioned about the fan blades. The one or more shrouds may be substantially straight cylinders, may be flared or bell-shaped, may comprise a cage, may have any other suitable configuration, or may be omitted altogether.Type: GrantFiled: March 24, 2010Date of Patent: August 21, 2018Assignee: DELTA T, LLCInventors: Richard M.

Patent number: 9574566Abstract: A fan comprises a rotatable hub, a plurality of fan blades coupled with the hub, and a plurality of air fences coupled with the fan blades. Each fan blade has a free end and an opposite end secured to the hub. The air fences are positioned at selected locations along the length of the fan blades, between the ends of the fan blades. Each air fence includes a fin, which may extend upwardly or downwardly from the fan blade. Each air fence may be formed of a resilient material and may be configured to allow the air fence to be snapped onto a fan blade. Each air fence may define an opening through which a fan blade may be inserted. One or more surfaces of the air fence may be contoured to complement a surface contour of an airfoil shaped fan blade.Type: GrantFiled: June 6, 2014Date of Patent: February 21, 2017Assignee: DELTA T CORPORATIONInventors: Richard M.
