Изобретение относится к электротехнике и может быть использовано для регулирования частоты вращения электродвигателя постоянного тока и для регулирования электрической мощности, поступающей от сети переменного тока к нагревательным и осветительным приборам. Целью изобретения является упрощение схемы снижения уровня радиопомех, создаваемых электроприводом. Электропривод содержит задатчик частоты вращения, выпрямительный мост, силовой ключ, электродвигатель, якорная обмотка которого шунтирована диодом и включена последовательно в цепь силового ключа, при этом в него дополнительно введены схема фиксации уровня напряжения, включенная в диагональ выпрямительного моста, и амплитудный ограничитель, а задатчик частоты вращения подключен параллельно разделительному конденсатору схемы фиксации уровня, а выход задатчика соединен через амплитудный ограничитель с управляющим входом силового ключа.The invention relates to electrical engineering and can be used to control the rotational speed of a DC motor and to control the electrical power coming from the AC network to heating and lighting devices. The aim of the invention is to simplify the scheme for reducing the level of radio interference generated by the electric drive. The electric drive contains a speed adjuster, a rectifier bridge, a power switch, an electric motor, the anchor winding of which is shunted by a diode and connected in series to the power switch circuit, while a voltage level fixation circuit included in the diagonal of the rectifier bridge, and an amplitude limiter are added to it, and an adjuster the rotational speed is connected parallel to the isolation capacitor of the level fixing circuit, and the output of the setter is connected via an amplitude limiter to the control input of the power circuit cha.
