Patent number: 8072107Abstract: The present disclosure relates generally to a permanent magnet, brushless motor comprising a primary rotor having alternating magnetic poles around a circumference, a secondary rotor similar to the primary rotor. The primary rotor may be free to rotate by approximately plus or minus one pole of the secondary rotor. As such, when the two rotor components have opposite polarities aligned, the motor may be in a field weakened state. Generally, the field weakened state may be the normal state of the motor. As a significant load is encountered, the rotors may automatically transition to a non-weakened state wherein similar polarities are aligned on the rotors. A permanent magnet, brushless motor as described herein may be employed at a motor level or integrated into a linear actuator, wherein the rotor of the permanent magnet, brushless motor may include a hollow shaft.Type: GrantFiled: September 11, 2008Date of Patent: December 6, 2011Assignee: Creative Motion Control, IncInventors: Keith Hochhalter, Mike Seiler

Publication number: 20050077855Abstract: An adaptable, servo-control system for force/position actuation generally includes an electric linear actuator and a controller. The controller interfaces with the electric linear actuator and with a number of I/O signals that are independent from the electric linear actuator. The controller interface to the independent I/O signals is transparent to the manner in which the I/O signals are produced. Rather the controller simply looks for the status of the I/O that is preferably received into the controller by hard-wiring or field bus I/O messaging such as from a industrial robot or programmable logic controller. The adaptable servo-control system is particularly suited to resistance weld systems wherein the electric linear actuator can replace the pneumatic actuator providing position and force actuation of the weld tip of the welding gun.Type: ApplicationFiled: December 3, 2004Publication date: April 14, 2005Inventors: Keith Hochhalter, Paul Romslo, Troy Erickson

Rather the controller simply looks for the status of the I/O that is preferably received into the controller by hard-wiring or field bus I/O messaging such as from a industrial robot or programmable logic controller. The controller utilizes the I/O signals to select a number of parameters to generate a motion profile for closed loop-controlled, position actuation or force actuation of the electric linear actuator.Type: GrantFiled: October 18, 2002Date of Patent: December 7, 2004Assignee: Tol-O-Matic, Inc.Inventors: Keith Hochhalter, Paul M.
