.The magnitude of the voltage and current of both the armature and shunt field coil. To decrease the speed when the load is increasing then increase the shunt field current while decreasing the armature voltage or current. To increase the speed while the load is increasing then increase the armature current while decreasing the shunt field current. The decreasing and increasing of these currents and voltages can be done by connecting a variable resistor in series or parallel with each of the armature and/or shunt field coil.
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
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
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
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.

It could be anything, it depends on the design of the motor and whether it is a high-power or a low-power motor.
he factors affecting the speed of a d.c. motor are, 1. The flux Φ 2. The voltage across the armature 3. The applied voltage V
A shunt dc motor has quite different characteristics from a series motor. Wired in series, the same current passes through the armature and the field winding and it is most unlikely that a shunt motor would have a field winding that is suitable for this. Therefore a shunt motor cannot be wired as a series motor in general because its field winding is designed for only a small current.
