Are the interpoles in a DC motor connected in series or in parallel with the armature?
Hi, Always interpoles are connected in series with armature. N.V.B.V. Prasada Rao
What does a volmeter do?
rust forms on an iron pipe after prolonged exposure to humid air what type of change does this illistrate? Chemical is it barometer/volmeter light meter/barometer volmeter/themometer themometer/light meter
What happens if load of DC series motor is disconnected?
In D.C Shunt motor, the field winding is connected parallel with the armature winding.. If you remove the supply to armature winding, the motor will stop after some time.
Why are the compensating winding used in dc motor?
compensating winding is used for equal load sharing of two generators running in parallel. while interpole winding is used to minimise the effect of armature reaction by supporting the main field.
What 3 factors that affect the output of a generator?
1:The strenght of the main magnetic Field. Determined by the strenght of the field magnets in a permanent magnet machine, or by the number of turns of wire on the field coils and the current through the coils in a wound field machine.2: The number of armature conductors connected in series, which cut the main magnetic field. Determined by the number of turns on armature coils and weather the armature is lap or wave wound, which determines the number of armature conductors connected in series.3: The speed at which the armature conductors cut the main magnetic field. The faster the armature cuts the magnetic Field, the higher will be the value of the voltage generated in the machine

What does a armature or rotor do?
The Armature(or rotor) is a electromagnet inside a motor and alters the magnetic field inside the motor when it rotates. In DC motors it is connected to a Commutator. In AC induction motors the armature isn't connected to a power source.
What is a volmeter?
a volmeter is a component in circuits which measures voltage.CommentI think you mean 'voltmeter'!
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.
Why is stationary armature preffered you commercial generators than moving armature?
The problem with a generator having a rotating armature is that the armature must be connected to its external load via slip rings and brushes. As power station alternators generate voltages up to 25 kV or so, and supply hundreds of amperes, the resulting arcing at the slip rings would be severe, and would require short maintenance cycles. Accordingly, it makes more sense for the armature to be stationary, and connected directly to its load, and have the field winding rotate instead, because the voltage/current applied to the field winding is quite low.
Why is armature connected to a sprinngy steel strip?
In an electric bell, a flat steel spring brings the armature back to its original position.
Basic principle of commutator motor meter?
It is based dynamometer principle with ironless motor with a wound armature having a commutator. The two coils are connected in series with supply and armature coil is connected in parallel to it.
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
What does a volmeter do?

Why armature winding is star connected for synchronous motor?
Because your momma said so
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
Why 3 point starter is called 3 point starter?
Because it has three terminals 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 starter :)
