Single track layer stator terminal assembly
View Patent ↗Disclosed is a terminal assembly for a stator of a dynamoelectric machine. The terminal assembly includes a at least five electrically conductive tracks arrayed in a single layer, each track configured and positioned for electrical communication with corresponding leads extending from the stator providing electrical connection between at least one lead of stator leads and a rectifier bridge. The tracks are at least partially encapsulated in a nonconductive casing.
1. A terminal assembly for a stator of a dynamoelectric machine comprising:
at least five electrically conductive tracks disposed in a single layer, each track configured and positioned for electrical communication between a rectifier bridge and at least one lead of a plurality of leads extending from the stator, at least six of the leads disposed in an arc of less than 90 degrees of circumference of the dynamoelectric machine; and
a nonconductive casing at least partially encapsulating the at least five tracks.
2. The terminal assembly of claim 1 , wherein one or more tracks of the at least five tracks includes a tab, the tab including a retaining hole that when encapsulated retains the one or more tracks including the tab within the terminal assembly.
3. The terminal assembly of claim 2 , wherein a first track of the at least five tracks extends radially outwardly in a local area to avoid interference with a second track of the at least five tracks.
4. The terminal assembly of claim 1 , wherein one or more tracks of the at least five tracks include a connector to electrically communicate with a corresponding lead of the plurality of leads.
5. The terminal assembly of claim 4 , wherein a first connector includes at least a first leg and a second connector includes at least a second leg, the first leg being disposed in a different axial location than the second leg.
6. The terminal assembly of claim 1 wherein the at least five tracks is six tracks.
7. The terminal assembly of claim 1 wherein the portion of one of the tracks of the at least five tracks is exposed from the nonconductive casing to allow for clearance of an overmolding die.
8. The terminal assembly of claim 1 wherein the nonconductive casing includes one or more attachment features to enable attachment of the terminal assembly to the dynamoelectric machine.
9. The terminal assembly of claim 8 wherein a first track of the at least five tracks extends radially outwardly in a local area around a first attachment feature and a second track of the at least five tracks extends radially inwardly in a local area around the first attachment feature.
10. The terminal assembly of claim 1 wherein at least six of the leads exit a stator core from adjacent core slots.
11. A terminal assembly for a stator of a dynamoelectric machine having a plurality of leads extending therefrom, the terminal assembly comprising:
at least six electrically conductive tracks disposed in a single layer, each track of the at least six tracks configured and positioned for providing electrical communication between at least one lead the plurality of leads and a rectifier bridge;
a first track of the at least six tracks extends radially outwardly in a local area around a first attachment feature and a second track of the at least six tracks extends radially inwardly in a local area around the first attachment feature; and
the first track of the at least six tracks extends radially outwardly in a local area, other than in the area around a first attachment, to avoid interference with the second track of the at least six tracks.
