Module 1 : Introduction to Electric Drives
Electromechanical Converter System
(Cont.)
Electrical energy input from the source = Mechanical Energy Output + Increased in stored energy in coupling field + Energy losses
% Overall Efficiency = ( Pmech / Pelect ) ? 100
Losses
(a) Loss in the winding resistance of the energy converter
(b) Core loss
(c ) Friction and Windage loss
