Filed:

Sep 12, 2001

Appl. No.:

09/950853

Inventors:

David L Brown - Westfield IN, US
Gerald R Stabel - Swartz Creek MI, US
Robert Anthony Lawrence - Kokomo IN, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

H02K015/16

US Classification:

29596, 29605, 29606, 29732, 310179

Abstract:

A method of inserting coils in slots of a stator is provided. The method includes interleaving a first set of first phase windings and a first set of second phase windings on an insertion tool. The method also includes activating the insertion tool to radially insert the first set of first phase windings and the first set of second phase windings in the slots of the stator. In one embodiment, interleaving the first set of first phase windings and the first set of second phase windings on the insertion tool includes forming the first set of first phase windings in first phase openings defined in the insertion tool, and forming the first set of second phase windings in second phase openings defined in the insertion tool.

US Classification:

264630

Abstract:

A method for manufacturing an inorganic honeycomb structure that resists water damage after drying comprises compounding a base batch mixture including inorganic powders, a batch cross-link agent, an aqueous vehicle, and a cross-linkable batch constituent, and forming the batch mixture into a honeycomb core or skin component while reacting the cross-link agent with cross-linkable batch constituent.

David Brown - Westfield IN, US
Robert Lawrence - Frankfort IN, US

International Classification:

H02K003/04
H02K017/00
H02K019/00
H02K021/00

US Classification:

310207000, 310214000, 029596000, 029606000

Abstract:

A stator core extends along a longitudinal axis and includes a plurality of radially-inwardly projecting teeth separated by intervening slots. Each tooth includes a tooth tip at the radially innermost portion of each tooth, thereby defining a slot opening. A wave-shaped conductor segment including a pair of segment ends having a first cross-section shape, a plurality of straight portions having a second cross-section shape and having a plurality of end-turn regions with a third cross-section shape disposed in between the straight portions in an alternating pattern is radially inserted into the stator core. After the conductor segment is inserted, the tooth tips are deformed so as to reduce the size of the slot opening, thereby providing for an improved magnetic flux path and slot fill percentage, as well as reduced cost and complexity without decreasing reliability.

Delphi Technologies, Inc. - Troy MI

International Classification:

H02K 1502

US Classification:

310 42

Abstract:

Described is a rotor assembly comprising: a circular iron core having a top and bottom side spaced from each other; extruded aluminum bars inserted into and around the circumference of the circular iron core; and a pair of extruded circular end rings attached to the top and bottom of the iron core and positioned. A manufacturing process for manufacturing the rotor assembly is also described.
