Abstract
Official abstract text for this publication.
An electric drive system may include a plurality of heat sensitive components, at least one temperature sensor positioned in or on each of the components and a system controller. The temperature sensors may be interconnected with the system controller to transmit temperature data from their respective heat sensitive components to the system controller. The system controller may be configured to transmit a reduced performance command in the event that a reached-temperature-threshold-limit signal is received from any one or more of the temperature sensors. System shutdown due to over temperature faults may be avoided.
First claim
Opening claim text (preview).
We claim: 1. An electric drive system comprising: a plurality of heat sensitive components; a plurality of temperature sensors in temperature communication with heat sensitive components; a system controller having a processor in bilateral communication with a reference unit; wherein the system controller continually receives temperature signals from the temperature sensors; wherein, if one of the temperature signals presents a temperature above a respective threshold temp…
