Abstract
An electric motor powers a fluidic pump fluidly connected to a hydraulic circuit. Operating the electric motor includes determining a heat transfer coefficient for the electric motor based upon a temperature of hydraulic fluid in the hydraulic circuit. A temperature of the electric motor is determined based upon the heat transfer coefficient. Operation of the electric motor is controlled based upon the temperature of the electric motor.
