Abstract
The condition and prospects of development of special electrical machinery intended to replace regulating units in automatic-control systems of nuclear-power plants are considered. Technical solutions to ensure the operation of such machines in a controlled self-running regime are proposed. Two different methods of motor design are described in relation to the type of actuator: on the basis of electromagnetic loads and on the basis of the ratio of the moments of inertia of the motor and drive. Variants with different ratios of copper to steel parts are analyzed, and the conclusion is drawn that it is necessary to coordinate this relation with the size and weight requirements and overload capacity.
