### title

ELECTRIC MACHINES FOR TRACTION APPLICATIONS

### description

Reviews the physics of electric machines.  Covers electric machine operation used both in motoring and generating modes necessary in traction applications.  The fundamentals of brush DC, PM synchronous, reluctance, and induction machines are explored.  Begins with the basics of DC machines and extends to the concept of field orientation in AC machines.
