Kotsur M. Effectiveness increasing of pulse control system of asynchronous motor with phase rotor

The work is devoted to the effectiveness increasing of the pulse control system in the circuit straightened current rotor, with the improved indexes of energy efficiency and decreasing of thermal isolation aging of asynchronous drive control system among the existent type of contactless control system in the circuit of the straightened current of rotor. The research of the electromagnetic, power-producing and thermal processes is conducted with the asynchronous motor of the modified pulse control system in comparison with classic pulse control system and asynchronous gate cascade. The effect of increasing of energy efficiency of motor drive is got due to the up recuperation of the accumulated electric energy in the wound of rotor in the electrical network with the help of fixed parameters of adjusting power of inverter. It is set that application of the modified pulse control system provides a most resource on power asynchronous motor among the type of contactless control system in the circuit of the straightened current of rotor.
