Question

A 50 hp , 250-V, 1200 r/min dc shunt
motor with compensating windings has
an armature resistance
( including the brushes, compensating
windings, and inter poles) 0.06 ohms.
Its field circuit has a total resistance
Radj + Rf of 50 ohms, which produces
a no- load speed of 1200 r/min. There
are 1200 turns per pole on the shunt
field winding.
Solve the following to find the speed
of this motor when its input current
is
100 A.​

Answer 1

Answer:

including the brushes, compensating

windings, and inter poles) 0.06 ohms.

Its field circuit has a total resistance

Radj + Rf of 50 ohms, which produces

a no- load speed of 1200 r/min. There

are 1200 turns per pole on the shunt
