US Patent:

7952253, May 31, 2011
Filed:

Sep 25, 2007
Appl. No.:

11/861147
Inventors:

Kevin Allen Bischel - Algonquin IL, US
Assignee:

Woodward, Inc. - Niles IL
International Classification:

H02K 1/16
US Classification:

310216057
Abstract:

A rotary actuator includes an outer enclosure having an inner diameter surrounding a hollow interior. A stack of stator laminations, each having a stator diameter greater than the inner diameter of the outer enclosure when in an unflexed state, are also included in the rotary actuator. Each of the stator laminations is configured to flex into a shape so as to be positionable within the outer enclosure and substantially conform to the inner diameter. The stator lamination thus forms a line-to-line fit with at least a portion of the outer enclosure to form an interface having a desirable reluctance.

7973445, Jul 5, 2011
Filed:

Jan 14, 2008
Appl. No.:

12/013751
Inventors:

Kevin Allen Bischel - Algonquin IL, US
Assignee:

Woodward Controls Inc. - Niles IL
International Classification:

H02K 1/06
US Classification:

310162, 310166, 310216004, 3102541, 310216057, 310216075
Abstract:

A rotary actuator includes a stator assembly positioned within an outer enclosure. A rotor assembly is positioned adjacent to the stator and is configured to rotate relative thereto and about a centerline axis of the rotary actuator. Each of the outer enclosure, the stator assembly, and the rotor assembly are arranged to carry a magnetic flux therethrough and form a flux path loop, such that as a magnetic flux flows through the outer enclosure, the stator assembly, and the rotor assembly, a torque is generated by rotation of the rotor assembly relative to the stator assembly.
