Considered actuator for industrial control systems on the basis of a shape memory material. The use of a material that has the ability to create large reversible strain by rearranging the martensitic domain structure in the magnetic field allows you to create effective short stroke actuators. Feature of the actuator is the pulse mode of magnetization of its active element. Designed magnetic system unit and proposed method of calculation of its parameters, taking into account the dependence of the resistance magnetizing coil segment and the number of turns in a segment from the area of its cross-section, also the limitations related by the size of the magnetic system and the power dissipated in the coil. Selected the optimum size of the coil segments, that provide the required level of tension magnetic field with a minimum size of magnetic system unit. Proposed mathematical model for the study of pulsed magnetization process of the active element of the device to determine the parameters of the magnetizing pulse.
