UNIT I INTRODUCTION 8
Basic Elements – Types of Electric Drives – factors influencing the choice of electrical
drives – heating and cooling curves – Loading conditions and classes of duty – Selection
of power rating for drive motors with regard to thermal overloading and Load variation
UNIT II DRIVE MOTOR CHARACTERISTICS
Mechanical characteristics – Speed-Torque characteristics of various types of load and
drive motors – Braking of Electrical motors – DC motors: Shunt, series and compound -
single phase and three phase induction motors.
UNIT III STARTING METHODS
Types of D.C Motor starters – Typical control circuits for shunt and series motors –
Three phase squirrel cage and slip ring induction motors.
UNIT IV CONVENTIONAL AND SOLID STATE SPEED CONTROL OF D.C. DRIVES
Speed control of DC series and shunt motors – Armature and field control, Ward-
Leonard control system - Using controlled rectifiers and DC choppers –applications.
UNIT V CONVENTIONAL AND SOLID STATE SPEED CONTROL OF A.C. DRIVES
Speed control of three phase induction motor – Voltage control, voltage / frequency
control, slip power recovery scheme – Using inverters and AC voltage regulators –
