QUESTION 3
A de shunt motor after running for several hours on constant mains of 350 V takes a field current
of 1.6 A. If the temperature rise is known to be 40°C, what value of extra circuit resistance is
required to adjust the field current to 1,6 A when starting from cold at 20°C?
The temperature coefficient of the motor's armature material is 0,0043/K at 20°C.
