Patent number: 11649855Abstract: A processing system includes a housing having an interior chamber and a central vertical axis extending through the interior chamber. A rotor is disposed within the housing interior chamber and is configured to support one or more work pieces. At least one lift actuator is configured to linearly displace the rotor along the central vertical axis between a lower, inactive vertical position and an upper, transfer vertical position. At least one levitation actuator is spaced above the rotor and is configured to exert a magnetic pulling force on the rotor to levitate the rotor upwardly from the transfer vertical position to a working vertical position. Further, an annular stator assembly is coupled with the housing, is disposed about and spaced radially outwardly from the rotor and includes a motor stator, the at least one lift actuator being configured to vertically displace the rotor relative to the stator assembly.Type: GrantFiled: April 28, 2022Date of Patent: May 16, 2023Assignee: SKF CANADA LIMITEDInventor: Daren Paul Tremaine

Patent number: 10971969Abstract: A rotor is for angularly displacing a work piece about a central axis and includes an annular, central axial portion centered about the axis and having opposing, first and second axial ends and inner and outer circumferential surfaces. An outer radial portion extends radially-outwardly from the first axial end of the central portion such that an outer generally annular cavity is at least partially defined between the central portion and the outer radial portion. Further, an inner radial portion extends generally radially-inwardly from the second axial end of the central portion such that an inner generally annular cavity is at least partially defined between the central portion and the inner radial portion. One or more motor stators are disposed at least partially within the outer or inner cavity and are each configured to angularly displace the rotor about the central axis, and preferably contactlessly drives the rotor.Type: GrantFiled: October 20, 2017Date of Patent: April 6, 2021Assignee: SKF CANADA LIMITEDInventors: Jeffrey Russel Smithanik, Daren Paul Tremaine, David Buechler

Patent number: 8269388Abstract: A rotor assembly includes a rotor having a central axis extending between the two opposing ends and a radial surface, and is rotatable about the central axis. At least one electromagnet is disposed proximal to and configured to exert magnetic force on a portion of the rotor. Further, a channeling member is disposed generally adjacent to the electromagnet and has a radial surface disposed adjacent to the rotor radial surface. As such, magnetic flux generated by the electromagnet extends generally radially between the electromagnet and the rotor portion and generally axially between the rotor portion and the channeling member so that the magnetic force biases the rotor both radially and axially to maintain the rotor at a desired position. Preferably, the assembly includes a plurality of magnets proximal to each end, two channeling members, and a tubular body extending between the channeling members and enclosing the rotor.Type: GrantFiled: February 2, 2009Date of Patent: September 18, 2012Assignee: Aktiebolaget SKFInventors: Jeffrey Russell Smithanik, Tracy Kathryn Strem, Daren Paul Tremaine

Patent number: 8270563Abstract: An apparatus includes an annular rotor that rotates about a rotational axis. A magnetic bearing system influences the position of the annular rotor in three-dimensional space and includes at least three actuators, wherein at least one actuator generates a force for lifting the annular rotor in a vertical direction, at least one actuator influences the position of the annular rotor in the radial direction of the annular rotor and at least assists in maintaining an annular gap between at least one non-magnetic bearing and the annular rotor during operation and at least one actuator influences the position of the annular rotor in an axial direction of the annular rotor. At least one radiation source may be fixedly mounted on the annular rotor.Type: GrantFiled: July 9, 2010Date of Patent: September 18, 2012Assignee: Aktiebolaget SKFInventors: Timothy Andrew Harris, Jeffrey Russell Smithanik, Daren Paul Tremaine

Patent number: 6267709Abstract: An isokinetic resistance apparatus includes a motor having an output shaft and a motor controller adapted to control power to the motor to maintain a first constant rotational speed of the output shaft. The output shaft of the motor rotates a driven shaft in a first rotational direction at a second constant rotational speed. A force receiving member is coupled with the driven shaft by a force transmitting linkage having a unidirectional clutch. A force exerted upon the force receiving member in the first rotational direction is transmitted through the driven shaft and the drive linkage to the output shaft of the motor. The motor controller adjusts power to the motor to compensate for such force and proportionately increase resistance to maintain the first constant rotational speed of the output shaft.Type: GrantFiled: October 18, 1999Date of Patent: July 31, 2001Assignee: Canadian Space AgencyInventors: Gary Jacques, Brent Warren King, Ken Wilbur Moore, Daren Paul Tremaine
