basically salient pole construction is adapted due to its simplicity in construction.
there are various types of arrangements such as bolted poles, dovetailed, double dovetailed, dovetailed and bolted etc.... but the application is limited due to two main factors:
1. the stresses developed in the fasteners (dovetails, bolts, fixing slots etc) due to high centrifugal forces.
2. high windage noises at high speeds due to large spaces between the poles.
the stresses can be countered upto a certain extent by using certain high tensile forged alloy steel such as 4140, 4340, ASTM grades etc.
but the noise factors require unique design of the poles to avoid windage and electromagnetic noises.

What is the difference between salient pole and non salient pole machines?
Rotors used in Synchronous alternators can be classified into 1)Salient and 2)Non-Salient Pole Rotors. Salient pole rotors are used in application with speeds from 100 to 1500rpm. They are alternative known as "projected pole" type of rotors. The poles mounted on the rotor are made of laminations made of steel. The poles are connected to the rotor shaft by means of dovetail joints. Each pole has a pole shoe around which the winding is wound. The salient pole rotor is generally used in applications where the prime mover is a hydel turbine or a combustion engine which have low or medium speeds. Salient pole rotors usually contain damper windings to prevent rotor oscillations during operation. Non-salient pole rotors are generally used in application which operate at higher speeds, 1500rpm and above. The prime movers in these applications are generally gas or steam turbines. These are sometimes known as "drum rotors". The rotor is a cylinder made of solid forged steel. The slots on which the windings are fixed are milled on the rotor. The number of poles is usually 2 or 4 in number. Since these rotors are cylindrical, the windage loss is reduced. The noise produced is also less. These rotors have higher axial length. These rotors do not need damper windings.
Which type of magnetic materials we do use for core of rotors stator of machines?
For the cores of rotors and stators in machines, soft magnetic materials are typically used, such as silicon steel and ferrites. These materials are chosen for their high magnetic permeability and low coercivity, which allow for efficient magnetic flux conduction with minimal energy loss. Silicon steel, in particular, is widely used in electric motors and transformers due to its excellent magnetic properties and low cost. Ferrites are often utilized in high-frequency applications due to their low eddy current losses.
What is 2 pole and 4 pole generators?
Both 2 pole and 4 pole generators are machines which produce electricity. Standard 2 pole versions are cylindrical while 4 pole versions use squirrel cage rotors.
How atlas copco screw compressor work?
Atlas Copco screw compressors operate using two interlocking helical rotors that compress air as they rotate. Air enters the compressor through an intake valve and is drawn into the space between the rotors. As the rotors turn, the volume of this space decreases, which compresses the air and raises its pressure. The compressed air is then discharged through an outlet, ready for use in various applications.
What type of supercharger has a positive displacement pump which consist of two rotors inside a housing?
turbo charger
Where in china was the helicopter invented?
It wasn't. Chinese had toys using rotors, but weren't trying to turn them into flying machines for human use.

Rotor blades balancing theory?
If you really want to see how this is done, try Googling "Chadwick Helmuth Strobex". They make machines to balance rotors and propellers.
Does rotors come with inter and outer bearings?
Yes, rotors typically come with both inner and outer bearings, depending on the rotor design and application. These bearings are crucial for ensuring smooth rotation and proper alignment of the rotor within the assembly. However, it's essential to check the specific product details, as some rotors may require separate purchases for bearings.
What were enigma machines like?
Enigma machines were essentially a system of rotors that were set a certain way every day. All of the German Navy had a schedule for which way to set the rotors, so that all of the machines would come up with the same results. When the keys were pressed, the rotors turned and came out with a different letter for each key press. For instance, if you pressed the letter "E" three times, you might come out with three random letters such as "D", "Z", and "K". Because the machines were set all the same way, they came up with the same random letters. The scrambled message was then sent to the recipient, who did the entire process in reverse to de-code the message. Previous codes had bases in literature or other media and were relatively easy to crack, while Enigma codes were mathematically based and had literally millions if not billions of solutions.
How many rotors on a 2001 Chevy Cavalier?
25 rotors. Cavaliers have 25 rotors on the car.
Why would the front rotors turn after changing the brake pads and rotors?
Possible wrong rotors???
Is there a special rotor for the 2001 Sport Trac brakes?
no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do. no nothing special, your typical rotors will do.
Do you need to grind the rotors when placing new brake pads?
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
How do heavy machines take to the air?
Heavy machines, such as helicopters and certain types of drones, achieve flight through the generation of lift. This is accomplished by their rotors or wings, which create a difference in air pressure when they move through the air. The engines provide the necessary thrust to overcome gravity, allowing these machines to ascend into the air. Additionally, careful design and engineering ensure they can maintain stability and control during flight.
What is reciprocating rotors?
A reciprocating engine is different than when using rotors. Rotors are used in a pistonless rotary engine, using one or more rotors and sometimes called rotary pistons.
Change front rotors on 2003 Camry?
Tap on the rotors with a hammer, after removing the tire and wheel and the brake assembly. The rotors will come loose. Slide the rotors off and reverse the process.
