Abstract

The electric motor 2 comprises permanent magnets and a magnetic material forming part of the rotor and of the stator in order to ensure magnetic immobilisation of the rotor during stoppage of the motor so that the means 6 of transforming the circular motion into a rectilinear displacement of the output rod 74 is a ball or roller circulating nut-screw pair with very low friction which delivers a high overall efficiency of the actuator.
