Abstract: A method is disclosed for braking a two-phase synchronous electric motor of the magnetized rotor type, driving a mechanical device. By this method the current supplied to the electric motor is controlled as a function of the actual position and the actual angular speed of the rotor within the braking period on the basis of information derived from the motor itself without additional detector devices. Perfectly proportioned braking is achieved taking into account individual motor and load characteristics and their possible variation, for example with temperature.
