A machine (100) propelled by an electric motor (210) and subject to a deration scheme is described wherein deration is specified by a combination of a temperature signal (512, 513, 514) indicating a degree to which a machine component is overheating. The machine includes an electronic controller (500) that receives a temperature signal (514) indicative of a current temperature status of the electric motor (210). The electronic controller receives a motor speed signal (515) indicative of a current speed status of the electric motor (210). The electronic controller (500) calculates, in accordance with a derating scheme, a deration value for the electric motor (210), the deration value being determined by applying a set of current operating state parameter values to the derating scheme. The set of current operating state parameters include: a motor speed parameter value; and a temperature parameter value.
