Difference between 12volt armature and 24 volt armature?
The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
What is the difference between an inductively-compensated and a conductively- compensated universal motor.?
An inductively-compensated universal motor uses an additional inductor to compensate for the motor's inductive reactance, improving speed regulation. On the other hand, a conductively-compensated universal motor uses additional resistors to compensate for the motor's armature reaction, enhancing speed control.
What is armature reaction in dc machines?
Armature reaction is the phenomenon in DC machines where the magnetic field produced by the current flowing in the armature windings interacts with the main magnetic field produced by the field windings. This interaction can distort the main magnetic field, causing changes in the machine's performance such as voltage regulation and torque production. Measures such as interpoles or compensating windings are used to counteract the effects of armature reaction in DC machines.
What is difference in resistance and reactance?
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
What is difference between armature and rotor?
An armature refers to the rotating part of an electrical machine, such as a motor or generator, that produces the electromagnetic field. A rotor, on the other hand, specifically refers to the rotating part of an electric motor that is connected to a shaft and used to generate mechanical motion. In essence, an armature generates the electromagnetic field while a rotor converts this energy into mechanical motion.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.

On the other hand, a conductively-compensated universal motor uses additional resistors to compensate for the motor's armature reaction, enhancing speed control.
What is difference between impedance and reactance?
Impedance is the net reactance(for Capacitors and inductors in the circuit) / Resistance of the circcuit whereas reactance is the prperty of the individual passive components ( only capacitors n inductors) to resist the flow of charge.
What is armature reaction in dc machines?

This interaction can distort the main magnetic field, causing changes in the machine's performance such as voltage regulation and torque production. Measures such as interpoles or compensating windings are used to counteract the effects of armature reaction in DC machines.
What is Comparison of armature controlled and field controlled DC servo motor?
Difference between field controlled and armature controlled is that field control is open loop and armature current is closed loop.
How does voltage commutation work in DC machine?
In voltage commutation process, the introduction of interpoles between main poles compensate armature mmf and reduces the effect of armature reaction.
What is salient and non salient pole alternator?
In salient pole alternator Xar is unequal in D-axis and Q-axis, due to non uniform air gap where as in non-salient pole Xar is equal in every axis due to uniform airgap between stator and rotor. Xar is armature reaction reactance.
What is difference in resistance and reactance?
Resistance is a concept used for DC. the current through a resistance is in phase with the applied voltage Reactance is used for AC the current through a inductive reactance lags the applied voltage by 90 degrees. the current through capacitive reactance leads the applied voltage by 90 degrees. the net reactance is the difference between inductive and capacitive reactance
What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
What is the difference between neutralization and salts?
Salts are the products of a reaction between an acid and a base; this reaction is called neutralization reaction.
