### title

ELECTRIC DRIVES FOR TRACTION APPLICATIONS

### description

Electric drives operation used both in motoring and generating modes necessary in traction applications.  The fundamental drives of brush DC, PM synchronous, reluctance, and induction machines are explored.  Begins with the basics of drives and extends to the device physics of power electronics used in drives.
