Abstract
Power capacitors for AC motors are mounted diametrically on associated transmissions. The power capacitors are in one embodiment annular and in another embodiment, arcuate. By having power capacitors mounted on transmission housings diametrically, cooling of the power capacitors is facilitated for both air and liquid cooling.
Claims13
A drive assembly for a vehicle comprising:
- an AC motor coupled to a transmission encased within a housing having proximal and distal ends;
- an inverter coupled to the AC motor, wherein the inverter is axially mounted and integral with the AC motor thereby creating an electric drive unit, wherein the inverter is configured to convert direct current to alternating current;
- and
- a power capacitor diametrically mounted on the housing of the transmission and electrically connected to the inverter of the electric drive unit of the AC motor.
