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 effect of field current on dc motor?
The field current of a dc motor provides the magnetic field that allows the motor to develop a torque when current flows through the armature..
What happens when dc is given to ac motor?
motor will not rotate
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
If you crank the shaft of a dc motor manually will the motor become a dc generator?
It depends on both the wiring of the motor and what if any residual magnetic field remains in the field windings. If there is some residual field, you will get some volts, but not many. If the motor has permanent magnets, it is effectively a dynamo.

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.
What is three point dc shunt motor starter?
L , F and A L - Line (connected to Supply) F - Field (connected to field of dc motor) A - Armature (connected to armature of DC motor) that's y it is called 3 point
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
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 are the Difference between dc motor and dc generator?
a motor Will do work by consuming power a generator is just the opposite
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
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 role does the armature do in a DC motor?
One of the role of the armature in the DC motor is to carry the current that is crossing the field. By carrying the current crossing the field, it creates the shaft torque in the rotating machine.
