Answer Posted / sagar
The armature of a DC shunt motor is connected to the external circuit via a commutator which can convert ac to dc as well as dc to ac. So AC supplied across the armature will be converted to DC so, current flowing in armature will be DC. But there will be an AC applied across the field winding, hence the field will vary with time from 0 value to max value. The machine will rotate but with serious vibrations induced in it, bcoz the torque will vary from 0 to a max value and that also 50-60 times per sec depending on frequency applied. (NB: don't compare this situation with synchronous m/c as there will b no rotating mf in this case)
