• To study and understand the operation and performance of AC Synchronous motor drives.
• To analyze and design the current and speed controllers for a closed loop solid state DC motor drives.

UNIT I	DRIVE CHARACTERISTICS	6

Electric drive – Equations governing motor load dynamics – steady state stability – multi quadrant Dynamics: acceleration, deceleration, starting & stopping – typical load torque characteristics – Selection of motor

UNIT II	CONVERTER / CHOPPER FED DC MOTOR DRIVE	9

Steady state analysis of the single and three phase converter fed separately excited DC motor drive – continuous and discontinuous conduction – Time ratio and current limit control – 4 quadrant operation of converter / chopper fed drive.

UNIT III	INDUCTION MOTOR DRIVES	6

Stator voltage control – energy efficient drive – v/f control – constant air gap flux – field weakening mode – voltage / current fed inverter – closed loop control,

UNIT IV	SYNCHRONOUS MOTOR DRIVES	6
