Abstract

A system that may include a bus bar that may include a mounting bracket configured to electrically couple the bus bar to a motor. The mounting bracket may also be configured to be removably coupled to the motor with at least one fastener. A transducer may be electrically coupled to the bus bar and have transducer elements. A dielectric material may be disposed between the bus bar and the transducer to prevent debris from contacting the active transducer elements and electrical arcing from occurring.

Claims (29)

1. A system comprising:

a bus bar;

a transducer coupled to the bus bar and having one or more transducer elements; and

a layer of dielectric material disposed between the bus bar and the transducer;

wherein the bus bar includes a mounting bracket configured to mechanically couple to a motor.

2. The system of claim 1 , wherein the layer at least partially encapsulates the transducer and at least partially encapsulates the bus bar.

3. The system of claim 1 , wherein the mounting bracket is configured to provide a space between the transducer and the motor, and the layer is at least partially disposed in the space between the transducer and the motor.

4. The system of claim 1 , wherein the bus bar is disposed relative to the transducer such that electrical current of the bus bar is detectable by at least one of the one or more transducer elements.

5. The system of claim 1 , wherein the dielectric material is an epoxy, a ceramic, a silicone, or a combination thereof.

6. The system of claim 1 , wherein the one or more transducer elements are configured to measure or detect one or both of an electrical current or a thermal load of the motor coupled to the bus bar.

7. The system of claim 1 , wherein the layer of dielectric material has a dielectric strength above 450 volts per mil.

8. The system of claim 1 , wherein the layer of dielectric material is between 1 millimeter and 15 millimeters thick.

9. The system of claim 1 , wherein the bus bar includes a bar portion and the mounting bracket extends as an appendage from the bar portion.

10. The system of claim 1 , wherein the bus bar is J-shaped.

11. A system comprising:

a bus bar including a mounting bracket configured to couple the bus bar to a motor, the mounting bracket also configured to be removably coupled to the motor with at least one fastener;

a transducer coupled to the bus bar and having transducer elements, the transducer coupled to the bus bar such that the mounting bracket forms a space between the transducer and the motor; and

a layer of dielectric material at least partially encapsulating the transducer, at least partially encapsulating the bus bar, and at least partially within the space between the transducer and the motor.

12. The system of claim 11 , wherein the dielectric material is an epoxy, a ceramic, a silicone, or a combination thereof.

13. The system of claim 11 , wherein the transducer elements are configured to measure or detect one or both of an electrical current or a thermal load of the motor when the bus bar is coupled to the motor.

14. The system of claim 11 , wherein the layer of dielectric material has a dielectric strength above 450 volts per mil.

15. The system of claim 11 , wherein the layer of dielectric material is between 1 millimeter and 15 millimeters thick.

16. A method comprising:

removing a first bus bar and first sensor from a motor; and

coupling a second bus bar with a second sensor coupled thereto to the motor to replace the first bus bar and the first sensor, a layer of dielectric material positioned between the second bus bar and second sensor; wherein the second bus bar includes a mounting bracket that extend as an appendage of the second bus bar.

17. The method of claim 16 , wherein coupling the second bus bar to the motor comprises at least one of electrically coupling, or mechanically coupling the second bus bar to the motor.

18. The method of claim 16 , wherein the second sensor includes at least one transducer element that is encapsulated by the layer of dielectric material.

19. The method of claim 16 , wherein the second bus bar is disposed relative to the second sensor such that electrical current of the second bus bar is detectable by at least one transducer element of the second sensor.

20. The method of claim 16 , wherein the second sensor includes transducer elements that are configured to measure or detect one or both of an electrical current or a thermal load of the motor after the second bus bar is coupled to the motor.
