The invention relates to methods and arrangements for actuating electromechanical transducers, in particular electric motors (3) having a voltage or a current, the optimum curve shape of which is previously determined from the data of a model transducer and which data are stored in a function memory (30). In this way, a prescribed power or torque characteristic, for example without fluctuations, can be achieved.

A method for controlling an electro-mechanical transducer incorporating at least a stationary part and a movable part, comprising the steps of: obtaining at least two distinct sets of data specific to said transducer, each said set of data relating to a type of perturbation known to occur in operation of said transducer and being in machine-usable form; determining in response to actual energization of said transducer at least one of elapsed time, linear position and angular position of the movable part to obtain a determined value; and modifying the energization of said transducer according to a schedule responsive to representative data from said two sets of data and to the determined value to compensate for said known perturbations, thereby to improve the operation of said transducer.
