motor will stop immwdiaely

Answer / balaji

the motor will stoped

Answer / raymond johnson

In a series wound motor, the stator is connected in series with the rotor so, if the series winding (stator) is opened, current ceases to flow thru the motor and it will come to a stop.

Answer / phanendra babu

in dc motors Eb is proportional to speed/flux,so if field
opens the motor speed will be dangerously increased and
leads to damage the motor.

Answer / nagaraju .n

does not complite the path of an supply that why motor stop.

Answer / rvg

The speed of a series wound DC motor will increase as soon
as the excitation deceases. But if we remove the excitation,
the motor speed will tend to increase, because of the
residual magnetism, and the rotor winding will burns off,
because of short circuit.

Answer / giridhar

in motors n is inversely proportional to flux from
Eb=z*n*fy.so if flux becomes 0 then n is infinite

Answer / sukesh

the speed of motor becomes increases.

how to calculate the current if i know power in MW and voltage 11kv/415v and also want to know that incoming cables for trnsformer

6 Answers   Daikin, KOC, Reliance,

We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
