Question
ourse
A series DC motor has a scrics-ficld winding of 25 turns per pole. Its armature resistance in 0.12, and its
field resistance is 0.05 2 The magnetization curve expressed in terms of magncto-motive force versus the
internal generated voltage at 1000 RPM is given by the following table:
EA (V)
F (Amp.tums)
50
95
150
1000
200
212
2000
243
3000
250
3500
229
253
4000
200
500
1500
2500
Those values were taken at speed n= 1000 RPM
When the motor is rotating at 900 RPM, with 220 V supply, and 100 Amp, its rotational losses are
2000 Watt.
What is the induced torque by this machine?
Select one:
O aInduced Torque -2175 N.m.
b. None
O c. Induced Torque = 2334N.m
d. Induced Torque = 196.3 N.m.
