Publication number: 20240019690Abstract: An actuator may include a stator supporting a magnet; a stationary pole; and a bobbin supporting a winding of a coil, the bobbin being coaxial with the stator and stationary pole, and positioned inside the magnet and outside the stationary pole. A gap may be provided between the bobbin and the stationary pole. A beam steering mechanism may include a mirror; a frame; a pivot anchor fixed to the frame and connected to the mirror; and an actuator. An output end of the actuator may be connected to the rear surface. A beam steering mechanism may alternatively include a flexure; a mirror attached to the flexure; a frame; supports fixed to the frame and the flexure; a pivot anchor fixed to the frame and connected to the mirror or the flexure; and an actuator. An output end of the actuator may be connected to the flexure.Type: ApplicationFiled: September 25, 2023Publication date: January 18, 2024Inventors: Simon Raab, Mark S. Longmuir

Patent number: 11090761Abstract: An actuator may include a stator, a pole; a bobbin; and windings provided around an exterior surface of the bobbin. The stator may include a stator body; and a plurality of magnets circumferentially arranged around an inner surface of the stator body. The stator, the pole, and the bobbin may be coaxial. An outer diameter of the pole may be smaller than an inner diameter of the bobbin such that the bobbin is movable in an axial direction over an exterior surface of the pole. An outer diameter of the bobbin may be smaller than an inner diameter of the stator such that the bobbin is movable in an axial direction inside the plurality of magnets circumferentially arranged around the inner surface of the stator body.Type: GrantFiled: September 4, 2019Date of Patent: August 17, 2021Assignee: THORLABS MEASUREMENT SYSTEMS INC.Inventors: Carl Brian Candiloro, Bradley Hunter, Kurt Sidor, Mark S.

Patent number: 10500676Abstract: An actuator utilizes a voice coil motor with one or more voice coil windings supported on a light weight moveable bobbin that connects at one end to move an object rapidly up to a small number of millimeters translationally along a system axis. The bobbin moves over a distal portion of a center pole of a stator, which supports the voice coil motor magnets. The pole, which acts as a flux path for the voice coil motor, also provides a thin film of air in a gap between the pole and the bobbin via an air path and corresponding holes at the distal end of the pole. The bobbin moves translationally relative to the pole on the thin film of air under the control of the voice coil motor.Type: GrantFiled: November 30, 2016Date of Patent: December 10, 2019Assignee: FARO TECHNOLOGIES, INC.Inventors: Carl Brian Candiloro, Bradley Hunter, Kurt Sidor, Mark S Longmuir
