Publication number: 20130049644Abstract: Disclosed is an air damper actuator operated by a brushless DC (BLDC) motor. An output shaft configured for connection to an air damper is driven by the BLDC motor. A controller receives position information indicative of an angular position of the output shaft and generates a control signal to control the BLDC motor for rotation by an amount based on the position information.Type: ApplicationFiled: August 22, 2011Publication date: February 28, 2013Applicant: HANSEN CORPORATIONInventor: Jeff Neumann

Patent number: 8322683Abstract: A damper actuator motor device includes a fan brake device which is secured to a motor rotor shaft and is configured to reduce motor rotation speed in a preferential direction. Preferably, the fan brake device has an asymmetric configuration, and is adapted to gather air radially in an enclosed cavity and discharge it axially in one direction. The fan device preferably is adapted to project a size that takes up more than half of the space of the cavity. When the motor is back driven, the fan brake device causes differentially pressure and air resistance in a confined area, producing a drag and braking force that increases with motor speed. The invention can be applied to motor actuators used to control air dampers and other valves in gas or fluid delivery systems. The invention can also be used to reduce water hammer in water delivery systems.Type: GrantFiled: July 10, 2006Date of Patent: December 4, 2012Assignee: Hansen CorporationInventor: Lincoln J. Dreher

Patent number: 7745966Abstract: A plurality of fan blades are secured to a rotor assembly of a single directional motor. When the motor is powered on, a force generated by the fan blades pushes the rotor assembly in a direction of a low friction thrust interface. When the motor is backdriven in a direction opposite the powered direction, the force generated by the fan blades pushes the rotor assembly in a direction of a higher-friction thrust interface, causing a tapered surface of the pinion and a tapered surface of a bearing retainer to be pressed against each other to produce a frictional braking force. The backdriven speed of the motor and drive device is therefore reduced, improving the reliability of the motor assembly. The invention can be applied to motor actuators used to control air dampers and other valves in gas or fluid delivery systems. The invention can also be used to reduce water hammer in water delivery systems.Type: GrantFiled: December 11, 2006Date of Patent: June 29, 2010Assignee: Hansen CorporationInventor: Lincoln J. Dreher

Patent number: 7739780Abstract: A specific illustrative embodiment of the present invention is disclosed here. The disclosed die tool that will assemble dissimilar materials to form a carrier plate of steel material and an insert of bearing grade material. One die used in the tool is carrier plate itself. The carrier plate provides a die opening to blank and pierce the bearing material into the steel material cavity.Type: GrantFiled: June 9, 2005Date of Patent: June 22, 2010Assignee: Hansen CorporationInventors: John M. Muncy, Steven Jay Steimel, Richard J. Turner
