Question

3-)The total Armature Winding resistance and series area winding resistance of a DC series motor are respectively; 52mΩ and 27mΩ’
stop. Motor armature coefficient Ka = 40. DC series motor at 200V to feed a mechanical load
it operates and is powered by a full load current of 325A. Flux value per pole is 50mWb
it is known. Brush losses are negligible. Core losses 250W and total on rotary parts
missing 60W. We will answer the following

(a) What is the value of the torque produced (induced moment)?

(b) calculate the speed of the engine.

(d) calculate the efficiency of the engine

(Clearly write down the formulas and process stages that you use for calculations.)
