Start of a synchronous motor with a dehumidified thyristor connection.
Abstract
The control circuits for starting a synchronous motor consisting of a thyristor static converter tightly connected to the excitation winding, semiconductors of the control system for ignition angle and a contactless control unit for bit resistance, the main elements of which is a diode and a thyristor. The control electrode of the thyristor is connected to the anode through a resistor and a zener, determines the voltage of opening thyristor. Puskovye characteristics and conditions of quenching the field is better than in systems with a tensile pathogen.
