ME2205 - Electrical Drives and Controls |
UNIT I INTRODUCTION |
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 factors |
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 IIISTARTING METHODS |
