It has less number of turns on the field and more number of turns on the armature. The number of turns on the armature is regulated by adapting lap winding and using large number of poles, especially for traction motors.
It has compensating winding which cancels the magnetic effect of armature current.
Since the field is weak, it has small air-gap.
To reduce transformer e.m.f., which gives commutating problem, these motors are run preferably from 16(2/3) cycles for 25 cycles supply.
These motors are suitable for maximum 400 V supply voltage
