Abstract

Improvements in the speed control system for three-phase asynchronous motors, particularly of the type comprising in its stator two independent windings, one of them driven by controlled normal power supply and the other powered by an equally controlled direct current, which will act as a complementary brake coil, according to whose improvements it is provided that the power supply of the motor, in each of its phases, has a control of thyristors placed in antiparallel, being carried out the control of the same from a control system capable of determining the firing angle, with which is achieved by varying the voltage applied to the motor, from zero to the nominal voltage of the supply network.
