However for series dc motor, cutting off the field winding simply decreases the speed of the motor and the motorstops. When field current is made to zero but still armature circuit is connected to supply. ... Because of the residual magnetic flux emf will be generated which helps in rotating ofmotor.

Hey buddy here is ur aswer !!
》In d.c shunt motor if fieldwinding supply is removed the motor back emf will drop to zero, hence the armature will draw more current to make up the emf.
》This results in blowing up of fuse.
》However for series dc motor, cutting off the field winding simply decreases the speed of the motor and the motor stops.
Hope u like !!
