Abstract

The invention relates to electrical engineering and can be used in a valve actuator. The aim of the invention is to increase energy performance and reliability. The valve motor contains a synchronous machine with a two-phase winding core, phases 1 and 2 of which are included in the diagonal of the bridge transistor switch, a rotor position sensor 28, a choke with two power windings 19 and 20 and a measuring winding 22 that is connected to the inputs of the comparator 23 with a control input and also four logical elements AND 24-27 and four logical elements EXCLUSIVE OR 29-32. The control inputs of the transistors 4-10, connected by the emitters, are connected directly to the outputs of the rotor position sensor 28, and the control inputs of the remaining transistors to the outputs of the corresponding EXCLUSIVE OR logic elements. At the same time, switching at the angle of less than 180 e-hail is ensured at the start-up and at low speeds of rotation, while at the same time ensuring the dynamic braking mode due to the included transistors 4-10. This increases the energy performance and reliability of 2 or Ј (L
