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
DifferEnces of long vs short shunt DC COMPOUND MOTORS?
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.....
What are the differences of Long shunt vs short shunt generator?
In long shunt the shunt field winding is in parallel to both generator and series field. In short shunt the shunt field is in parallel to generator only.
If the rheostat were connected in series with the shunt field winding and the combination placed across a 120 V dc line what shunt field current variations could be obtained from your motor?
It could be anything, it depends on the design of the motor and whether it is a high-power or a low-power motor.
Draw a schematic diagram of a 3 point starter showing various components internal connections and out going leads connected to a dc shunt motor?
A schematic diagram of a 3-point starter for a DC shunt motor includes a few key components: a starter handle, a series coil (or relay), and a shunt motor connection. The starter handle is connected to the series coil, which is in turn connected to the armature winding of the motor. The outgoing leads connect the motor's armature to the power supply, while the shunt field winding is connected to the power supply directly. The starter allows for a gradual increase in voltage and current to the motor, protecting it from inrush current during startup.
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.
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
Does series field winding have more resistance or a shunt field winding?
shunt field winding have more resistance than series field winding ************sai ganesh ************269*******

What is shunt and series motor?
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.
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor

What would be the shunt field current of your motor if the shunt field winding is excited by?
It could be anything, it depends on the design of the motor and whether it is a high-power or a low-power motor.

What would the power loss be if the series field winding of dc motor connected directly across the 240 V dc supply?
Detailed Solution. For a constant back emf, flux is inversely proportional to the speed of the motor. If field winding is disconnected accidentally, the speed would dangerously increase in order to maintain the back emf of the motor
What is shunt current and a armature current?
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.
