US Patent:

58641874, Jan 26, 1999

Filed:

Mar 27, 1997

Appl. No.:

8/827145

Inventors:

Cesar Gonzalez - Troy MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

H02K 4100

US Classification:

310 12

Abstract:

A linear motor armature includes a sealed metal case having a base portion with at least one cooling channel formed therein and having a central chamber. An epoxy block is disposed within the central chamber. A lamination stack is disposed within the epoxy block. A coil assembly is disposed within the lamination stack, and the coil assembly is cooled by means of the cooling channel. Preferably, more than one cooling channel is provided to facilitate bi-directional cooling flow.

Appl. No.:

9/157183

Inventors:

Cesar Gonzalez - Troy MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

H02K 4100

US Classification:

310 12

Abstract:

An apparatus and method for cooling a linear motor armature assembly is provided for maintaining minimal separation between a motor housing and a magnet plate, wherein the motor housing has a housing opening formed at a side of the motor housing facing the magnet plate. The method includes: a) covering the housing opening with a thin sheet of non-magnetic material having a thickness of less than approximately 0. 015 inch to enclose the coil assembly within the motor housing; and b) drawing a cooling fluid through the motor housing to create a negative pressure within the cooling fluid and to cool the coil assembly.

Inventors:

Cesar Gonzalez - Troy MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

H02K 4100

US Classification:

310 12

Abstract:

A linear motor armature includes a sealed metal case having a central chamber formed therein. A lamination stack is disposed within the central chamber and includes a coil assembly disposed within the lamination stack. The central chamber is flooded with an electrically nonconductive fluid, such as oil, for cooling the coil. The cooling oil is flowed in opposing directions to facilitate bidirectional cooling of the coil.
