STATE THE ENERGY BALANCE EQUATION AS APPLICABLE TO ALL SITUATION OF ELECTROMAGNETIC MACHINES. [7 marks]

Energy balance equation
A Machine accept energy in two forms either through mechanical or electrical from its terminal system. We take energy input to be positive. As the function of the mechanical energy conversion terminal input will normally be negative(-ve) of the total energy inputs, some converted, some stored and the rest dissipated in loss.
Therefore, (Elect Energy input) + (Mech Energy input)
= (Store field energy) + ( stored mech energy) + Dissipation
Comparable relations apply to energy changes and to energy rates (i.e power)
Energy changes: dwe + dwm = dwf + dws + de
Energy rate = Pe + Pm = dwf/dt + dws/dt + P
So energy rate equation becomes
Pe + Pm = P

On the 4th of November I officially became a member of the exclusive 1st student with distinction after five years of no such record, in the history of The Polytechnic Ibadan, Faculty of Engineering to graduate with distinction as a DPP students since its establishment in 2011. My unrelenting power to solve problems, have made me to create a platform where student can get valid information anywhere, anyplace at anytime Evolving education world wide 🌎
