SU1676018A1 - Gated electric motor having a current regulator - Google Patents

Abstract

The invention relates to electrical engineering. The aim of the invention is to improve the quality of regulation and expand the functionality by providing two braking modes, for this purpose the valve motor is equipped with three-input logic adders 37, 38, a setting device 39 of the Stop operation modes. Each group 12, 13 of the keys of the frequency converter 5 is equipped with second additional inputs connected to each other, connected to the output of one of the adders. The first and second inputs of the adders are pairwise combined and connected respectively to the direct and inverse outputs of the counting trigger 26. The third inputs of the adders are combined with the third inputs of the Forbidding elements 23, 29 and connected to the output of the sensing sensor 39. successive operation of logic adders 37, 38 and logic elements; Ban 23, 29, thereby realizing the dynamic braking and braking opposition; the counting trigger organizes the alternate operation of the anode and cathode groups 12, 13 keys 5 frequency converter. 3 il.
