Answer Posted / naveen
Torque is proportional to flux and current.
reason why starting torque is high in series motor only is:
in DC series motor, flux is also proportional to current since the field winding is series with DC motor.
and the reason why its high in start is :
in starting back emf is 0 . current=(V-Ef)/R when Ef is 0 current attains high value which decreases as the speed of motor increases and thus the Ef.
