7408433, Aug 5, 2008

Filed:

Jan 12, 2007

Appl. No.:

11/652622

Inventors:

James C. Irwin - Beavercreek OH, US

Assignee:

Saia-Burgess Inc. - Vandalia OH

International Classification:

H01F 7/08

US Classification:

335228, 335229, 335234, 335272

Abstract:

A pin lock is movably mounted for linear movement along a longitudinal axis. A magnet, preferably a permanent magnet, is mounted for limited rotation between the pin extended and pin retracted positions. An electromagnet provides a controllable electromagnetic field which encompasses at least a portion of the permanent magnet. A ferromagnetic latch is located within the magnetic field of the mounted magnet in each of the pin extended and pin retracted positions. A mechanical interconnection between the pin lock and the permanent magnet for moving the pin lock when the permanent magnet is rotated wherein the movement extends or retracts the pin lock between its pin extended and pin retracted positions. Reversing the electromagnetic field of the electromagnet serves to rotate the magnet so that the pin lock moves from one to the other of the two positions.

International Classification:

H01F 1/00
H01F 3/00
H01F 7/00

US Classification:

335277, 335257, 335247, 335248

Abstract:

An electromagnetic actuator () comprises a stator (), a piston (), and a key (). The stator comprises a stator frame () having an axial direction (), the stator frame in turn comprising a magnetic member () and a base (). The base () is separated by a gap () in the axial direction from the magnetic member () and positioned so that magnetic flux extending through the magnetic member () also extends through the base (). The piston () is configured to reciprocate within the stator frame () in the axial direction (). The key () is configured and position both to locate the base () with respect to the stator frame (and thereby provide the gap) and to absorb energy when the piston () strikes the base. A flux transfer flange () is configured to concentrate magnetic flux extending through the magnetic member () in a radial direction into the base ().

International Classification:

H01F 3/00

US Classification:

335261, 335255, 335279, 335281

Abstract:

Embodiments of soft latching solenoids comprise a coil assembly (); a plunger assembly (); at least one flux conductor () comprising a flux circuit. The coil assembly () is fixedly situated with respect to a solenoid frame (). The plunger assembly () is configured to linearly translate in a first direction along a plunger axis () upon application of a pulse of power to the coil assembly (). The flux conductor(s) () is/are positioned radially exteriorly to the plunger assembly () to form the flux circuit. The flux circuit comprises the solenoid frame (), the plunger assembly (), and the at least one flux conductor (). The flux circuit is arranged and configured so that the plunger assembly () is held in a plunger detent position upon cessation of the pulse of power.

Appl. No.:

13/935655

Inventors:

James C. IRWIN - Beavercreek OH, US

International Classification:

H02K 33/00

US Classification:

310 1204

Abstract:

A haptic actuator ((X)) provides compact mounting for a haptically-actuated assembly by mounting at least a portion of the haptically-actuated assembly to magnetic circuit members of the haptic actuator. The haptic actuator comprises a first magnetic member (); a second magnetic member (); a field generator (); and a resilient connector (). The first magnetic member () is configured to have a driven part () of the haptically-actuated assembly mounted to the first magnetic member (). The second magnetic member () is selectively separated by at least one air gap from the first magnetic member () and is configured to have a stationary part of the haptically-actuated assembly () connected to the second magnetic member (). The second magnetic member () is positioned at least partially within the field generator () and the first magnetic member () is positioned externally to the field generator (). The resilient connector () is configured to connect together the first magnetic member () and the second magnetic member () in a manner to allow selective closing and opening of the at least one air gap upon selective activation and de-activation of the field generator ().

International Classification:

H02K 134
H01F 708

US Classification:

310181

Abstract:

A force motor having four magnetic lanes arranged annularly around an axially movable central shaft, where the shaft is connected to an armature which also moves axially with the shaft within a gap located between two coils forming each lane of the motor. The four magnetic lanes are electrically and magnetically independent and provide three levels of safety-redundancy in case of coil failure.
