Can a shunt field winding be used as a series field winding in dc series motor?

What happens if field winding of a running dc shunt motor suddenly breaks open?
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
What is the demagnetizing component of armature reaction?
it is the flux which is flowing opposite to the main field flux and demaganetize it... in order to eliminate this demagnetiszing component we have to connect the compensating winding in series with the armature winding which develop the flux in it oppose to the demagnetizing component
How many winding in DC motor?
that depends on,motor size, number of coils, company,and wire gauge. you can make a simple dc motor with just 10 winding or less. it would be very low on torque and speed though.
What happens to d.c motor when Field is weakened in DC?
when the field winding of dc motor opens the flux is zero so the speed is inversely propotional to speed ,so motor runs at dangerous speed...........

Why dc supply is being used in studying the effect of temperature on the field winding resistance of a dc motor?
Because tests on a dc motor are always done using dc.
What happens if field winding of a running dc shunt motor suddenly breaks open?
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
What is DC shunt motor?
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
What is the demagnetizing component of armature reaction?
it is the flux which is flowing opposite to the main field flux and demaganetize it... in order to eliminate this demagnetiszing component we have to connect the compensating winding in series with the armature winding which develop the flux in it oppose to the demagnetizing component
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor

Why you have to connect DC supply to the induction motor?
To start an induction motor we have to excite field. The excitation is done by connecting the DC supply to the field winding's.
How many parallel paths in a wave winding of a 4 pole dc motor?
2
Why you use seperately exited field winding in DC motor?
Because it's easy to control the speed and torque of the motor.
What field setting for a dc shunt motor wired in series on high voltage?
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.
