Filed:

May 4, 2001

Appl. No.:

09/845857

Inventors:

Jeremy P. Maus - Bloomington MN
Richard A. Mink - Ossian IN
Nathan L. Schuler - Fort Wayne IN
Steven W. Weissner - Fort Wayne IN

Assignee:

International Truck Intellectual Property Company, L.L.C. - Warrenville IL

International Classification:

B60R 1604

US Classification:

180 685, 280784, 296189

Abstract:

A battery mounting assembly for mounting batteries to a vehicle. The battery mounting assembly has lower battery tray and an upper battery tray disposed below and above one another respectively. The battery mounting assembly is constructed to move and deform in predetermined ways when it is subjected to relatively large forces such as might occur when the vehicle is involved in a traffic accident. The battery mounting assembly has one or more bumper components intended to protect batteries mounted to the battery mounting assembly from being subjected to a direct impact. Steel components of the battery mounting assembly are coated with an elastomer that has a high electrical resistance.

Appl. No.:

10/304673

Inventors:

Patrick Lee Jansen - Alplaus NY, US
Steven Wells Weissner - Fort Wayne IN, US

Assignee:

General Electric Company - Niskayuna NY

International Classification:

H02K015/02

US Classification:

29596, 29598

Abstract:

A method for fabricating an induction motor rotor lamination includes using an indexed notching die to punch a plurality of closed rotor slots at different distances from a center point of rotation by punching a first rotor slot, changing the position of a center point of the rotor lamination with respect to the notching die, and punching a second rotor slot. In another embodiment, a plurality of rotor slit patterns are punched using a variable depth indexed notching die including at least two rotor slit punching portions, one being deeper than another, by punching a first rotor slit pattern, changing the depth of closure of the notching die, and punching a second rotor slit pattern with the second rotor slit pattern having a different number of rotor slits than the first. In another embodiment, each rotor slit is open to and off center with respect to its respective rotor slot, and rotor laminations are stacked by positioning some of the rotor laminations in an orientation with is turned over and rotated with respect to others of the rotor laminations; filling the rotor slots and the rotor slits with cage material; and machining outer surfaces of the rotor laminations. In another embodiment, uniformly spaced identical rotor slots are punched and modulation is created by punching a contoured outside diameter or by inserting slot wedges of molded magnetic material.
