US Patent:

57433526, Apr 28, 1998

Filed:

Sep 3, 1996

Appl. No.:

8/707258

Inventors:

John Michael Miller - Saline MI
Robert Howard Erickson - Novi MI

Assignee:

Ford Global Technologies, Inc. - Dearborn MI

International Classification:

B62D 504

US Classification:

180446

Abstract:

In one embodiment of the present invention, an electric assist power steering system includes steerable wheels and a polyphase induction motor mechanically coupled to provide assistance in steering the wheels. Additionally, the system includes a DC power source such as a vehicle battery or an alternator. The system also includes an inverter to convert the output voltage of the DC power source into AC phase voltages for the induction motor, the AC phase voltages having line-to-line amplitudes less than or equal to the output voltage of the DC power source. Another embodiment of the present invention includes an induction motor designed to have rotor back iron thinner than stator back iron. Such a motor will have a rotor of reduced diameter, minimizing the rotational inertia of the rotor. The present invention enables a practical electric assisted power steering system and the numerous advantages derived from an electric assisted system.

International Classification:

H01F 4100
H01F 136
H02K 1500

US Classification:

29596

Abstract:

A method of forming a 360. degree. ceramic permanent magnet by utilizing a hot isostatic pressing technique on a ceramic preform paterial cylindrically formed and placed inside a deformable metal housing having an inner diameter that is approximately the same but only slightly larger than the outer diameter of the preform. A solid steel mandrel is provided in the center diameter of the hollow cylindrical preform. Crystal alignment and densification of the ceramic material is achieved by using the hot isostatic pressing technique applied to the outside of the housing, preform and mandrel assembly.

International Classification:

H05K 7/20

Abstract:

A double-sided cold plate includes a manifold comprising openings extending from a first surface of the manifold through the manifold to a second surface of the manifold forming recesses within the manifold and an inlet channel and an outlet channel fluidly coupled to the recesses within the manifold, a plurality of first heat sinks coupled to the first surface of the manifold enclosing the openings on the first surface, and a plurality of second heat sinks positioned adjacent each other along a length of the manifold and coupled to the second surface of the manifold, enclosing the openings on the second surface, a width of the plurality of second heat sinks is greater than a width of the manifold thereby forming an overhanging portion on each lengthwise side of the manifold, the overhanging portion configured to mechanically support a plurality of electrical components positioned around a perimeter of the manifold.

International Classification:

H05K 7/20

Abstract:

A cold plate having a manifold includes a recess extending from a first side to a second side of the manifold, where the recess includes openings to the recess positioned lengthwise along the first side and a single opening to the recess on the second side, an inlet and an outlet fluidly coupled to the recess, a plurality of plates fastened to the first side enclosing the openings, a heat sink fastened to the second side enclosing the single opening on the second side, and a plurality of fluid cores one of each positioned between each of the plurality of plates and the heat sink. The plurality of fluid cores include a flow distribution insert, a first plate fin positioned between the flow distribution insert and the heat sink fastened to the second side, and a second plate fin positioned between the flow distribution insert and the heat sink.
