Abstract
An electric motor drive system includes a fan configured to cool power electronic components of the electric motor drive system. The electric motor drive system also includes a temperature sensor disposed proximate an air inlet of the fan and configured to sense an ambient temperature of air entering the air inlet. In addition, the electric motor drive system includes a processor communicatively coupled to the temperature sensor and configured to determine at least one of a drive prognostic and a derating requirement based on the sensed ambient temperature.
