Basic structures and characteristics of classic regulated electromotor propulsion. Regulation of spin speed and position of directional motor. Scalar and vector management of asynchronous motors (speed management through voltage and frequency), regulation of moment and speed. Modern microprocessor regulated propulsions with directional and asynchronous motors (structures, characteristics, adjustments and acommodation to working mechanisms). Electromotor propulsion as a part of distributed management system based on programmable logic controllers (PLC). Systems for positioning – servo propulsions. Voltage regulation of directional generators. Voltage and frequency regulation of synchronous generators. Management system for diesel aggregate.
