Course detail

Electrical microdrives

FEKT-NEMIAcad. year: 2011/2012

Electric drives play an important role as electromechanical energy converts in most production processes.
The controlled drives /small power/we can find in a different
applications : automobiles, vending machines,medical and laboratory technology, aviation and aeronautics, mechanical engineering,construction tools,office machinery and data processing, measuremet technology etc.
The function of all type of motors and semiconductor supply devices, microprocessor control, PLC technology - are explained.
