Dynamoelectric machine conductor
View Patent ↗A dynamoelectric machine conductor includes a bus including a central portion, a first connectable site of the central portion connectable with a first conductor and a first arm having a second electrically connectable site connectable with a second conductor. A first fused portion of the first arm located between the first connectable site and the second connectable site, the first fused portion being electrically interruptible to open a circuit between the first connectable site and the second connectable site. A second arm having a third connectable site connectable with a third conductor, and a second fused portion of the second arm located between the first connectable site and the third connectable site. The second fused portion being electrically interruptible to open a circuit between the first connectable site and the third connectable site.
1. A dynamoelectric machine conductor, comprising:
an electric machine bus including a central portion;
a first electrically connectable site of the central portion connectable with a first flexible conductor;
a first arm that extends from the central portion having a second electrically connectable site connectable with a second flexible conductor;
a first at least one fused portion of the first arm having an orifice including a continuous outer boundary that defines, at least in part, first and second reduced cross sectional portions, the orifice extending through the first arm located between the first electrically connectable site and the second electrically connectable site, the first at least one fused portion being electrically interruptible to open a circuit between the first electrically connectable site and the second electrically connectable site;
a second arm that extends from the central portion, having a third electrically connectable site connectable with a third flexible conductor; and
a second at least one fused portion of the second arm having an orifice including a continuous outer boundary that defines, at least in part, first and second reduced cross sectional portions, the orifice extending through the second arm located between the first electrically connectable site and the third electrically connectable site, the second at least one fused portion being electrically interruptible to open a circuit between the first electrically connectable site and the third electrically connectable site.
2. The conductor of claim 1 , wherein the bus is rigid.
3. The conductor of claim 1 , wherein the bus is elongated.
4. The conductor of claim 1 , wherein the bus is metal.
5. The conductor of claim 4 , wherein the metal is a highly conductive alloy.
6. The conductor of claim 4 , wherein the metal is copper or brass.
7. The conductor of claim 4 , wherein the bus is plated.
8. The conductor of claim 1 , wherein the at least one fused portions are electrically interruptible by melting due to current flow through the reduced cross sectional portions.
9. The conductor of claim 1 , wherein the bus is sized and shaped so as to be formable by stamping.
10. The conductor of claim 1 , wherein the orifice extending through at least one of the at least one fused portions is noncircular.
11. The conductor of claim 1 , wherein the first and second at least one fused portions are configured to break with conduction of less current than the first or the second flexible conductor.
12. The conductor of claim 1 , wherein the first and second at least one fused portions are configured to conduct a current that is less than a selected over current condition.
13. The conductor of claim 1 , wherein the bus is connectable with the flexible conductor by welding.
14. The conductor of claim 1 , wherein the bus is connectable with the flexible conductor by soldering.
15. The conductor of claim 1 , wherein the bus is arcuate shaped.
16. The conductor of claim 15 , wherein the first electrically connectable site is on a portion of the bus extending radially outwardly from the arcuate shape.
