Appl. No.:

09/854884

Inventors:

Robert Anthony Lawrence - Kokomo IN

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

H01F 304

US Classification:

29609, 29596, 29732, 310216

Abstract:

A segmented core for an electric machine includes segments stamped from coated electric steel. The segments each have a first end, a second end, and winding openings. A predetermined number of segments are placed end-to-end to form layers. The layers are stacked such that each of the layers is staggered from adjacent layers by a predetermined rotation angle. The winding openings of each of the layers are in vertical alignment with the winding openings of the adjacent layers. The stack of layers is secured to form the segmented core.

International Classification:

B23P 1500

US Classification:

29890, 2940701, 2940709, 734321

Abstract:

A catalytic converter is constructed by measuring a substrate to be placed within the outer shell or can, wrapping the substrate in a selected mat and loading the package (mat and substrate) into the can. The can is larger than it will be at completion of manufacture to render such loading easier. Subsequent to loading, the measurement of the substrate is used to direct the degree to which the can is reduced in outside dimension such that a selected annulus is created between the substrate and can, said annulus being occupied by said mat.

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.

International Classification:

H01R 25/00

US Classification:

439121, 439754, 429 93

Abstract:

A voltage tap apparatus functions as both a voltage tap and a cell isolator for conductive case battery cells that are joined end-to-end in a series chain. The apparatus includes conductive leadframe elements partially encased in a plastic frame that engages the joined cells about their juncture, with portions of the lead-frame elements exposed to electrically contact the conductive cases of the cells. In a first embodiment, the plastic frame is in the form of a hinged clamp that closes about the juncture of the cells, and the lead-frame elements are routed to terminals formed on one end of the frame. In a second embodiment, the plastic frame and a connector are mounted on a printed circuit board and the leadframe elements in the plastic frame couple the battery cells to the connector.

Abstract:

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. The circular end rings are configured to have a plurality of openings configured to align with and receive a portion of the extruded aluminum bars when they are inserted into the iron core. A manufacturing process for manufacturing the rotor assembly is also described.

International Classification:

H02K001/18

US Classification:

310/218000

Abstract:

A stator core and method of making, the stator core and a plurality of separate poles are formed from lamination segments that are each stamped from a single piece of stock. The core includes a plurality of fixed pole segments and a plurality of engagement openings configured to receive and engage the separate pole segments. The method of making the stator core allows for maximum use of the material from which the laminations of the stator are stamped as well as an efficient use of the available space within the stator core. In addition, the method allows for maximum copper slot fill.

US Classification:

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.
