a. Induced Torque = 54.5 N.m
b. None
c. Induced Torque = 50.9 N.m
d. Induced Torque = 45.6 N.m.
Transcribed Image Text:A 180-V, DC motor is connected as a cumulatively-compounded DC motor. Its characteristics are given
below:
RA = 0.10 2
Rs = 0.05 2
RF = 125 2
Radj = 100 2
NF = 1000 turns NSE= 10 turns IL, rated = 55 A
nm=1800 RPM
This motor has compensating windings and interpoles.
When the motor is rotating at 1680RPM, 180 V supply, 52 A armature current, the rotational losses are
933 Watt.
What torque is induced by this motor?
