A mathematical model of the of pulse-phase control systems is developed, dynamic modes of induction machines in the electric drive of scraper and screw conveyors are investigated. It is established that the use of quasi-frequency control ensures the achievement of a stable low speed and the improvement of the starting properties of the drive in comparison with the use of double-speed motors. References 12, figure 4.
Key words: mathematical model, quasifrequency control, induction machine, solid rotor, transient mode.
