Publication number: 20090322267Abstract: In a normal operating mode, a motor controller provides motor drive current to windings of a motor based on sensor signals to drive the windings in a normal commutation sequence, and monitors for occurrence of a motor stall condition. Upon detecting the motor stall condition in a given commutation state, then in a first driving step, the windings are momentarily driven according to an advanced commutation state, and during the first driving step, a reverse transition of the sensor signals to a state corresponding to a preceding commutation state is detected.Type: ApplicationFiled: June 30, 2008Publication date: December 31, 2009Applicant: HR TEXTRON INC.Inventors: M. Robert Mock, Raymond Y. Liu

Publication number: 20090108702Abstract: An electric motor has a stator, and a rotor disposed within the stator. The stator has a set of stator laminations and a set of windings held in position by the set of stator laminations. The rotor is arranged to rotate about an axis. The set of stator laminations is arranged into a stack. Each stator lamination includes an outer section, and a set of teeth coupled to the outer section. Each tooth of the set of teeth extends from that outer section toward the axis. Each tooth has (i) a first end which is proximate to the outer section and distal to the axis, and (ii) a second end which is proximate to the axis and distal to the outer section. A width of the first end of each tooth is substantially greater than a width of the second end of each tooth.Type: ApplicationFiled: September 23, 2008Publication date: April 30, 2009Applicant: HR TEXTRON, INC.Inventor: M.

Publication number: 20090101752Abstract: A locking assembly has a base and a rotary shaft which is capable of rotating relative to the base. The rotary shaft has a shaft body and a set of capture portions supported by the shaft body. The locking assembly further includes a set of detention mechanisms supported by the base. The set of detention mechanisms is arranged to (i) initially apply retention force to the set of capture portions to provide resistance against rotation of the rotary shaft from an initial angular position, and (ii) remove application of the retention force from the set of capture portions in response to an amount of rotational torque on the rotary shaft. The amount of rotational torque on the rotary shaft exceeds a predetermined threshold and is sufficient to substantially rotate the rotary shaft from the initial angular position.Type: ApplicationFiled: October 18, 2007Publication date: April 23, 2009Applicant: HR TEXTRON INC.Inventors: M.

Patent number: 7520192Abstract: Methods and apparatus are disclosed for providing reduced friction in drive screw assemblies, including electromechanical actuator (EMA) assemblies. A drive screw assembly is disclosed that includes a drive shaft, a drive screw, and a screw head. A stationary guide collar having a guide bore and a support surface receives the screw head or a portion of the drive screw. The guide collar may be fixed in angular relation to the screw head. As the screw head moves on a linear path during rotation of an associated drive shaft, a supported surface slides in only linear motion with respect to the support surface of the guide collar and as a result friction forces due only to linear motion are generated. Rotational friction forces and associated efficiency and power losses are consequently reduced or eliminated in the drive screw assembly.Type: GrantFiled: November 18, 2004Date of Patent: April 21, 2009Assignee: HR Textron, Inc.Inventor: M.

Publication number: 20070248432Abstract: A blind fastener is provided comprising a core bolt comprised of a bolt shaft and a bolt head. A metal sleeve is included comprising a rigid cylindrical base and a malleable cylindrical tail, the metal sleeve is positioned around the bolt shaft with the malleable cylindrical tail in communication with the bolt head. A travel stop feature is formed on the rigid cylindrical base opposite the malleable cylindrical tail. A drive feature includes a threaded bolt section extending from a foot end of the bolt shaft and a drive nut rotatably thereto. The drive nut allows the core bolt to be pulled within the metal sleeve such that the bolt head compresses the malleable cylindrical tail to form a retention button.Type: ApplicationFiled: April 21, 2006Publication date: October 25, 2007Inventors: Gary Cassatt, Dinh Vu, Robert Mock

Patent number: 7259551Abstract: Position sensing of movable elements including but not limited to machine components is disclosed. Motion of a movable element can produce motion of a magnetic field, which can be detected by magnetic sensors. The motion and/or variations of a magnetic field and/or a magnetic flux may be produced by any combination of a motion of the sensors, associated magnets, or associated magnetic material. Magnetic sensors maybe capable of measuring either rotary, or linear motion, or both. Such sensors can provide indication of an incremental position change, an absolute position, or both. Absolute position and high-resolution position sensing may be produced for measurement of either linear and/or angular motion. Suitable magnetic sensors include, but are not limited to, Hall effect devices and/or magneto-resistive elements, and may include multi-element magnetic sensors. Suitable signal conditioning and/or control means such as control electronics can be used to receive output signals from the sensors.Type: GrantFiled: September 7, 2006Date of Patent: August 21, 2007Assignee: HR Textron, IncInventors: M.

Patent number: 7109679Abstract: Oscillation and other disturbance damping is provided for a system having a load driven by an electric motor, e.g., an electromagnetic actuator. Damping is achieved using feedback in an active mode, where power is supplied in a normal operation mode of the electromagnetic actuator. Feedback may be provided by measured force (or torque) transmitted between the actuator and load mass. A gear train or other mechanical advantage device may be connected between the electromagnetic actuator output and load, this combination forming an electromechanical actuator (EMA). Instead of force or torque, acceleration of the load may be used as a feedback signal. In one embodiment, active mode damping uses the motor's actual current as a feedback signal. In certain or all active damping versions of the invention, a high pass filter is preferably used to receive feedback signals and filter out low frequency feedback. Alternatively, damping is achieved in an inactive (passive) mode of motor operation, e.g.Type: GrantFiled: March 9, 2004Date of Patent: September 19, 2006Assignee: HR Textron, Inc.Inventors: Ralph D.

Patent number: 7095193Abstract: A brushless DC motor apparatus includes a housing and a stator assembly coupled to the housing. The apparatus further includes a magnetic rotor assembly rotatably coupled to the housing. The magnetic rotor assembly is configured to rotate within the housing in response to electric currents through windings of the stator assembly. The apparatus further includes position sensors which are configured to provide position signals identifying angular position of the magnetic rotor assembly relative to the stator assembly. Each position sensor includes (i) a Hall-effect sensor disposed distally from the windings, and (ii) magnetic circuit members having first end portions adjacent the windings and proximate rotor magnets and second end portions adjacent the Hall-effect sensor. Use of such magnetic circuit members enables the Hall-effect sensors to reside a greater distance from the windings vis-à-vis conventional brushless DC motors which position sensors adjacent to stator coils within motor casings.Type: GrantFiled: May 19, 2004Date of Patent: August 22, 2006Assignee: HR Textron, Inc.Inventors: Michael I.
