Answer:
If the shunt winding is open the motor won't start, but if the shunt open while the motor is running, the motor will keep on running as if nothing went wrong, except if the wire of the winding get maniacally between the stator and the fields the motor can be damaged beyond repair. But normally the shunt windings is done with very thick conductors, so the chance that the shunt will go open is zero.
No. A d.c. 'shunt' motor is one whose stator's field windings are connected in parallel with its rotor windings ('shunt' is simply an archic term for 'parallel'); it does not mean that the rotor can function without brushes.
Yes. The field is provided by the shunt windings, which are connected in parallel with the supply. You may be confusing a motor with a generator, as you cannot start a shunt generatorwithout residual magnetism.
A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.
base speed is the speed with full voltage on the shunt this speed is mostly from the number of poles , single pole fastest max speed is when you weaken the shunt the limit is the amount of power the armature can take and thing like bearings an strength of the reinforcement of the windings
when the field winding of a running dc shunt motor suddenly breaks open the motor fails to run because in the motor the stationary winding is armature and rotatory is field winding
A series motor is one in which the field windings are in series with the armature windings. So the torque is proportional to the square of the supply current.'Shunt' is an archaic term for 'parallel'. So a shunt motor is one in which the field winding is in parallel with the armature windings. So the torque is proportional to the supply current.

Shunt Motor
Yes. The field is provided by the shunt windings, which are connected in parallel with the supply. You may be confusing a motor with a generator, as you cannot start a shunt generatorwithout residual magnetism.
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
If the starting torque required is too high for a shunt motor, it could lead to stalling or jerky operation at startup. This can cause overheating and damage to the motor windings due to increased current draw. It is important to match the motor's torque capabilities with the load requirements to prevent these issues.
The terms 'shunt' and 'armature' apply to a particular type of d.c. motor, in which the field windings are connected in parallel with the armature windings. 'Shunt' is an archaic term for 'parallel', so the term 'shunt', in this context, means that the field winding is connected in parallel with the armature winding. The terms 'shunt current' and 'armature current', then describe the currents flowing in the shunt winding and armature winding, respectively.

the basic difference is ,in short shunt motor the series field winding wont carry any current under no load condition whereas in long shunt motors series winding will carry no load current.....
