it is the single winding Xmer which work on self induction
principle

Answer / nyo satt paing

The auto transformer is generally used in low power
applications where a variable voltage is
required. The auto transformer is a special type of power
transformer. It consists of only one
winding. By tapping or connecting at certain points along the
winding, different voltages can
be obtained.

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
