Abstract
Official abstract text for this publication.
In accordance with exemplary embodiments, a drive system is provided for an electric or hybrid electric vehicle that provides reduces electromagnetic emissions. The system includes, but is not limited to, an electric motor and a transmission having a collar for receiving a portion of a drive shaft. The collar has an inside diameter proportioned to an outside diameter of the drive shaft to cause capacitive coupling between the transmission and the drive shaft thereby reducing electromagnetic emissions along the drive shaft.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle, comprising: an electric motor; an inverter electrically coupled to the electric motor and providing power to the electric motor; a drive shaft having an outside diameter; and a transmission mechanically coupling the drive shaft to the electric motor, the transmission including a collar having an inside diameter configured to receive a portion of the outside diameter of the drive shaft and form capacitive coupling between the transmission and…
