- (TRUE OR FALSE) - Shunt motor should not be started on no-load. - Field copper loss is likely to have highest proportion at rated load ofthe DC generator. - In a DC generator, the iron losses mainly take place in the commutator. - Energy conversion of DC generator is based on the principle ofproduction of dynamically terminal voltage. - Increasing the speed of DC motor, the back emf will decrease but theline current falls. - The current drawn by the armature of DC motor is directly proportionalto torque. - Lenz’s law rule is used to determine the direction of rotation of dcmachines. - Compound dc motor at no-load it regulates highest speed. - The direction of this force is perpendicular to both the wire and themagnetic field in DC motor. - The direction of DC motor induced emf is such that the same of thearmature current.Complete the wiring diagrams as per Worksheets 6-A and 6-B then solve for "A" through "K" for the DC motor on Worksheets 6-A and 6-B when it is running at capacity and its specifications are as follows:Rated input = 125 volts, 16 ampsArmature Resistance = 0.3 ohms(Ω)Shunt Field Resistance = 50 ohms (Ω)Series Field Resistance 0.6 ohms (Ω)Rheostat Resistance = 12.5 ohms (Ω)A)power consumed by series field(P-series)a)56.58W b)153.6W c)265.42W d)1523.WB)power consumed by shunt field(P-shunt)a)56.58W b)153.6W c)265.42W d)1523.56WC)power consumed by armature resistance(P-arm)a)56.58W b)153.6W c)265.42W d)1523.56WD)percent efficiency of the machine( % eff) if rotational loses are 850 Wa)30% b)64% c)86% d)99%5.
