Filed:

Sep 14, 2001

Appl. No.:

09/952539

Inventors:

Frank D. Sorg - Middletown IN
Ronald D. Gentry - Cicero IN

Assignee:

Delco Remy America, Inc. - Anderson IN

International Classification:

B23K 1124

US Classification:

219110, 219 5622

Abstract:

The method of the present invention involves setting a penetration threshold as well as a maximum weld time when hot staking armature conductors to the slots of a commutator. To perform each weld, an electrode is forcibly contacted with the top conductor in one of the slots of the commutator. Next, electric current is delivered to the electrode, causing the conductor to heat and begin to deform within the slot. During this time, the electrode moves further into the slot. If the electrode reaches the penetration threshold in the commutator slot before the maximum weld time is reached, current to the electrode is terminated. After terminating current to the electrode, the electrode remains in contact with and applies force to the conductor until the maximum weld time is reached. After the maximum weld time is reached, the electrode is removed from contact with welded conductor.

International Classification:

H05K 334
B23K 108

US Classification:

228259

Abstract:

A dip soldering process includes a reservoir of molten solder and a solder ladle for immersion therein to refresh the supply of ladled solder. The ladled solder is displaced by a displacement plunger to thereby overflow the ladle and carry with it surface contamination. Continued immersion of the plunger during the soldering operation of the workpiece accomplishes continual flow across the soldered workpiece thereby removing any contaminants which rise to the surface or are introduced by the workpiece.

Abstract:

A rotor for an electric machine includes a rotor core defining an axis of rotation, a plurality of windings positioned on the rotor core, and a commutator extending from the rotor core. The commutator includes an elongated contact portion and a riser connected to an end of the elongated contact portion. The riser includes a circumferential wall extending radially outward from the end of the elongated contact portion. The circumferential wall includes a V-shaped top portion with a plurality of notches formed in the V-shaped top portion.
