US Patent:

7135792, Nov 14, 2006

Filed:

May 11, 2005

Appl. No.:

11/127469

Inventors:

Thomas J. Devaney - Watchung NJ, US
Chun Li - Plainview NY, US

Assignee:

Dexter Magnetic Technologies, Inc. - Fremont CA

International Classification:

H02K 41/00

US Classification:

310 12

Abstract:

An embodiment of the invention is a particular arrangement of permanent magnets that generates a higher strength and more uniform magnetic field than existing permanent magnet arrangements for a voice coil motor. The permanent magnet arrangement of an embodiment is based on the Halbach arrangement of permanent magnets. The increased magnetic field strength and uniformity allows for a voice coil motor that is both capable of higher frequency actuations as well as more uniform force over the full stroke of the actuation.

International Classification:

H02K 41/03
H02K 41/02

Abstract:

A mover for a linear motor system includes a magnet subassembly. The mover includes a magnetic structure disposed on at least one side of the magnet subassembly and creating with the magnetic subassembly a resultant magnetic field. The magnetic structure being centered on a detected center of the resultant magnetic field. The mover includes a body structure mounted on or with reference to the magnetic structure to position a physical center of the body structure at approximately the detected center of the resultant magnetic field.
