Formation of starting characteristics of single-phase electric drives with thyristor control

Abstract

The possibility of creating a rotating magnetic field in a single-phase motor of any type using two pairs of counter-parallel thyristor elements, one of which can provide natural or artificial current switching, is shown. The use of two types of thyristor switching allows the static and dynamic characteristics of single-phase electric drives to be generated in two directions of rotation. starting torque of the magnitude and combination of the angles of control of the thyristor elements. The values current commutation angle providing the maximum starting torque and smooth acceleration dvigatelya.Issledovaniya held at AVM.
