Abstract: A method and an apparatus are provided for maximizing energy efficiency of an electric drive system including an electric motor and a load. In the method, the torque characteristics of the system can be selected from two types of behavior: linear and quadratic behavior of a torque of the motor in respect to a rotational speed of the motor. The method gathers a plurality of data points and with which behavior the data points correlate best. The torque characteristics to be used are determined on the basis of the correlation, and the motor is controlled on the basis of the determined torque characteristics. The apparatus implements the method.
