초록 ▼

An electrical assembly for a motor controller is disclosed that includes an electrical lead. The electrical lead has a conductive trace within an insulating material and that extends a length between first and second ends. An electrical pad is in electrical continuity with and extends from the conductive trace through the insulating material at the first end. The pad includes an aperture providing a securing feature. An electrical component is supported by and integral with the second end, in one example. The electrical component is in electrical continuity with the conductive trace at the second end. A bus bar provides a joint having a first cross-sectional area. The electrical lead is flexible and is removably secured to the joint by the securing feature to provide electrical continuity from a capacitor to the bus bar. The flexible electrical lead has a second cross-sectional area substantially less than the first cross-sectional area.

1. A motor controller comprising: a capacitor;a bus bar providing a joint having a first cross-sectional area;a flexible electrical lead removably secured to the joint to provide electrical continuity from the capacitor to the bus bar, the flexible electrical lead having a second cross-sectional area substantially less than the first cross-sectional area. 2. The motor controller according to claim 1, wherein the flexible electrical lead includes a conductive trace covered in a polyimide insulating material. 3. The motor controller according to claim 2, wherein the bus bar and the conductive trace comprise copper. 4. The motor controller according to claim 2, wherein the flexible electrical lead includes a conductive pad extending from the conductive trace through the insulating material at the first end, the conductive pad including an aperture providing a securing feature. 5. The motor controller according to claim 4, wherein flexible electrical lead includes a generally rectangular cross-section, and comprising a fastening element extending through the aperture and removably securing the first end to the bus bar. 6. The motor controller according to claim 1, comprising a printed wiring board supporting the capacitor and a second end of the flexible electrical lead, which is opposite a first end of the flexible electrical lead that is secured to the bus bar, the printed wiring board including a conductive layer providing electrical continuity between the second end and the capacitor. 7. The motor controller according to claim 1, wherein the flexible electrical lead is connected directly to the capacitor at a second end of the flexible electrical lead. 8. The motor controller according to claim 7, comprising a housing surrounding the second end and the capacitor, the flexible electrical lead extending through the housing to a first end, the housing filled with a potting material. 9. The motor controller according to claim 1, comprising an inductor and a chassis, the bus bar and the capacitor supported by the chassis, and the bus bar electrically connected between the inductor and the capacitor. 10. The motor controller according to claim 1, wherein the second cross-sectional area is 2.5 percent or less than the first cross-sectional area. 11. The motor controller according to claim 1, wherein the bus bar is configured to provide 220 amps in a steady state condition and 480 amps in a transient starting condition.
