Patent number: 10892078Abstract: An electric actuator assembly having a support housing, a first stator magnetic field generating assembly secured to the support housing and a movable armature assembly. The movable armature assembly includes a plate assembly having a center support. The electric actuator assembly also includes a first armature magnetic field generating assembly configured to provide magnetic fields operative with a first stator magnetic field generating assembly to provide linear motion of the movable armature assembly along a reference axis, the first armature magnetic field generating assembly including first and second magnetic assemblies secured to opposite sides of the center support. In another embodiment, the electric linear actuator includes a rotational component coupled to a linear component to move therewith. The rotational component includes an armature magnetic field generating assembly being one of longer or shorter than a stator magnetic field generating assembly.Type: GrantFiled: December 7, 2017Date of Patent: January 12, 2021Assignee: MTS SYSTEMS CORPORATIONInventors: Andrew Gregory Simon, Andrew Timothy Reiner, Paul Martin Krueger, Bradley Dean Schulz

Patent number: 10739398Abstract: A method of constructing an electric linear displacement motor for use in a testing device includes providing a stator having as stator housing with internal coils and a through bore extending from a first end of the stator housing to the second end of the housing. An armature having magnets retained therein is inserted into the stator housing such of the armature is supported by the first end support and the second end support. A plurality of set screws are inserted into threaded openings proximate both the first end and the second end of the housing. The set screws then support and retain the armature such that there is an annular gap between the armature and the coils.Type: GrantFiled: October 23, 2017Date of Patent: August 11, 2020Assignee: MTS Systems CorporationInventors: Tyler B. Kuhlmann, Bradley Dean Schulz, Paul M. Krueger, Don Curtis Petersen

Patent number: 9696229Abstract: A force applicator assembly is disclosed to calibrate an in-situ force transducer (or load cell) in a force (load) applying test machine. The force applicator includes stationary member configured to be secured to fixed structure, a moving member, a load cell operably coupled to an end of the moving member, and a differential screw assembly connecting the moving member to the stationary member. A coupling assembly can be used to assure that only tension or compression loads are applied. The coupling assembly can be configured if desired such that no tension or compression loads can be applied. A method to calibrate an in-situ force transducer in a force applying test machine is also provided and uses a force generator and the coupling assembly.Type: GrantFiled: October 7, 2014Date of Patent: July 4, 2017Assignee: MTS Systems CorporationInventors: Bradley Dean Schulz, Paul M. Krueger

Patent number: 9455608Abstract: A testing apparatus includes a crosshead and a head assembly. The head assembly includes a head cover having an interior volume. An electric actuator, controls and other electric components are located within the interior volume, wherein the motor, controls and other electric components generates heat when energized. A divider within the interior volume separates a first volume from a second volume. The first volume includes the heat generating electric motor, controls and electric components and the second volume contains substantially no heat generating components. The head assembly includes at least one fan within the second volume that draws cool air from outside the head cover and forces the cool air through the second volume and into the first volume to remove heat.Type: GrantFiled: March 15, 2013Date of Patent: September 27, 2016Assignee: MTS Systems CorporationInventors: Bradley Dean Schulz, Tyler B. Kuhlmann, Paul M. Krueger, Richard Leo Taylor

Patent number: 9270155Abstract: An electric linear displacement motor for use in a testing apparatus includes a stator assembly having a stator housing and a plurality of coils within the stator housing. An armature is positioned within the stator housing and includes a plurality of magnets along a length of the armature. A bearing assembly is attached to the first end of the stator housing and includes a bearing housing containing a bearing. A first end portion of the armature engages and is carried by the bearing. A brake assembly is coupled to the first end of the armature and the bearing housing. The brake assembly includes a moving portion coupled to the armature and a non-moving portion coupled to the bearing housing wherein the moving portion has less mass than the non-moving portion and therefore reduces the moving mass of the armature.Type: GrantFiled: March 15, 2013Date of Patent: February 23, 2016Assignee: MTS Systems CorporationInventors: Tyler B. Kuhlmann, Bradley Dean Schulz, Paul M. Krueger

Patent number: 9121791Abstract: A testing machine includes a pair of vertical columns, a crosshead selectively positionable on the vertical columns, and a head assembly supported by and movable with the crosshead. The head assembly has an electric actuator, a support that can be selectively moved from a first position when the test machine is operated to a lowered position. The support supporting components are related to powering or controlling the electric actuator, said components are exposed for servicing in the lowered position.Type: GrantFiled: March 15, 2013Date of Patent: September 1, 2015Assignee: MTS Systems CorporationInventors: Bradley Dean Schulz, Paul M.
