(A shunt DC motor has a total resistance value for all conditions as Ra= 2 Q and under full load conditions (nominal load) armature current is Ia = 10 A. The nominal terminal Voltage for the motor is Vr-300 V and total value for field circuit resistance for all conditions is Rf=150 Q. Under full load conditions (nominal load), find the internal generated Voltage (EA), excitation circuit current (field current) (If), (total supply current flow, from electrical source) line current (IL), electrical input power (Pin) supplied from the source.

A separately excited DC motor drives a constant torque mechanical load. The armature resistance is 0.20 and the nominal armature current is la=74A. The nominal rotational speed of the motor is 1150 rpm. The armature winding is supplied from a 220V DC source. Rotational losses can be neglected. a) What is the load torque if the machine draws the nominal armature current while running at the nominal rotational speed? b) Under the same load, the field winding current is decreased by 20%. Calculate the new rotational speed. Should the machine be kept operating in this regime for a prolonged time? Why? c) Calculate the output power and the efficiency of the machine in this regime (ignore field winding losses). d) With the same load, the field winding voltage is increased back to the nominal value. If the armature winding voltage is decreased to 180V, calculate the new rotational speed. e) Sketch the motor and the load torque-speed characteristics for the conditions in a), b) and d).…

A 250 V DC shunt generator has a constant loss of 1250 W. Find the load current for maximum efficiency. Also find the value of maximum efficiency and output power times maximum efficiency. The armature resistance is 0.10.
A 230-V dc shunt motor takes a current of 5A at no-load. The resistance of armature and field circuits are 0.50 ohm and 230 ohm, respectively . If the maximum efficiency occurs at full load current, what is the value of this current? A 14 hp, 240 v shunt motor draws an armature current of 50 A at full-load. The armature resistance including brushes is 0.25 ohm. Calculate the total resistance of a starting box which wound permit this motor to develop a starting torque equal to twice that at full load.
