What does salient pole mean?

Definition of salient pole : a magnet pole that projects toward the armature of an electric machine — compare consequent pole.

What is salient pole in motor?

In salient pole type of rotor consist of large number of projected poles (salient poles) mounted on a magnetic wheel. Salient pole rotors have large diameter and shorter axial length. They are generally used in lower speed electrical machines, say 100 RPM to 1500 RPM.

What is a salient pole generator?

Salient pole Generators will have large diameter and short axial length. Pole shoes cover 2/3 of the pitch. Salient Poles are laminated in order to reduce eddy currents. They are used in hydraulic turbines or diesel engines. Salient Pole Synchronous Generators are employed in Hydro-Power plants.

What do you mean by salient and non-salient pole rotor?

Basically, the rotating part of an electrical machine is the rotor. Salient pole type or projected pole type rotor ( low speed, more number of poles, kaplan turbines ) Non-salient type or smooth cylindrical type rotor ( high speed, 2 or 4 poles, pelton wheel )

What does non salient mean?

adj. 1 prominent, conspicuous, or striking. a salient feature. 2 (esp. in fortifications) projecting outwards at an angle of less than 180°

What is salient and non salient?

First, as it is said before, cylindrical pole (non-salient) machinery tends to rotate rapidly, but salient pole machines break down due to mechanical stress. Another difference between salient pole and cylindrical pole is that salient pole is more stable than the cylindrical pole (non-salient).

Why salient pole rotor is laminated?

Lamination is done in any machine to reduce the effect of eddy current loss. Eddy Current can be induced within nearby stationary conductors by a time-varying magnetic field created by an AC source only(Not DC ). Since Rotor of the cylindrical synchronous machine is excited by DC supply,so the rotor flux is DC.

Where are salient pole generators used?

Hence salient pole generators are used in hydropower plants. Non-salient pole-type rotors are used in high-speed alternators having speeds between 1500 rpm to 3000 rpm. Salient pole rotors are used in low-speed devices, from 100 rpm to 1500 rpm.

What is salient pole rotor?

What are Salient Pole rotors? Salient pole rotors are large in diameter and shorter in length. They are typically used in lower speed electrical machines (100 RPM to 1500 RPM). Salient pole rotors normally require damper windings to avoid oscillations of rotors during operation.

What is a salient status?

that is prominent, conspicuous, or otherwise noticeable compared with its surroundings. Salience is usually produced by novelty or unexpectedness, but can also be brought about by shifting one’s attention to that feature.

What are the examples of salient characteristics?

For example, my child may have a cup with a handle and that handle might be the salient feature for her. Another child may have a sippy cup, and that spout may be the distinctive feature for him. Each person is drawn to specific information about something, depending on interests, needs, strengths, and circumstances.

What is salient pole construction details?

In salient pole type of rotor consist of large number of projected poles (salient poles) mounted on a magnetic wheel. Construction of a salient pole rotor is as shown in the figure at left. The projected poles are made up from laminations of steel. The rotor winding is provided on these poles and it is supported by pole shoes.

What are the advantages of salient pole?

Cheap

What is salient pole of a generator?

Salient pole Generators will have large diameter and short axial length Salient Poles are laminated in order to reduce eddy currents They are used in hydraulic turbines or diesel engines Salient pole generators will have typical speed about 100 to 375 rpm.
