How much gap in between stator inner diameter and rotor outer diameter?
.050
Synchro motor and its function?
A Synchro Motor is a Elecrical motor consition out of a single-phase Inner/Rotor windings, and a Three-phase Outer/Stator windings. The Outer/Stator windings are connected Electricly in a Star formation. ... ie: The inner ends of each the three windings are connected to one another. And the outher ends will then be connected to another Synchro Motors outer ends. The Inner/Rotor windings are connected to a single-phase AC power supply. The Rotor Windings in turn transfer energy over to the Outer/Stator windings. The Stator Windings are 120 degrees appart. And therefore depending on the Rotation of the Inner/Rotor Windings the Outer/Stator Winding get a different magnatude of magnetic flux, transferring a different amout of current flow to each of the three Outer/Sator windings. That bring us to the use of a Synchro Motor: ... A Syncrhro Motor works in pairs of 2 or 3, and are used to transfer rotational oriantation from one Synchro motor to another. Depending on how the Synchro Motors are connected to one another you can mirror the rotation from the first motor to the second. For standard Synchronigation you would connect The 3 Outer/Stator windings as such (1-1) (2-2) & (3-3). To mirror the Rotation you could connect (1-2) (2-1) & (3-3). Remember I said you could have 3 Synchro motors... The Third is wired differently inside... it has 3 Inner/Rotor windings & 3 Outer/Stator windings. The Rotor & Stator winding are connected in a star formation. The third Synchromotor bring about a difference in rotation. You could add or subtract rotational oreantions. A = Synchro Motor 1 ...B = Synchro Motor 2 (with 3 Stator & 3 Rotor windings) ...C = Synchro Motor 3 A+B=C Or A-B=C Synchro motors are used in ships, for opening & clossing valves from the bridge to for instance the Engine room. A more advanced system of the synchro technology integrates with a Servo Motor, that in turn can controls the rudder of the ship. Other uses are in Analoge computers & Electronic Weapon Guidence Systems.
What is ac generator?
An AC or alternating current generator is a piece of machinery that produces AC electricity. Most commonly this machine is powered by steam.in simple terms it consists of a series of blades that are turned by steam.a magnetic field is excited on the rotor which then cuts through lines of magnetism that are present on the stator by the power grid. As more power is applied to the rotor, the turbine must spin harder,not faster, to push more power onto the grid. RPM of rotor is determined by the number of poles in the stator. Most commonly a turbine will spin at 3600rpm.... or, 60 times per second giving us the USA electrical grid a 60Hz frequency. This is scratching the paint on AC generation but its a start.
What variables in a micro hydro system could you change to get more electricity from it?
The size of the stator should be expanded by using higher gage and more winding, the size of the rotor should also be expanded to bigger size. The most important is the speed of the water flow which will gear up the rotor faster.
Earth revoles on its axis true or false?
Yes, it does though it wobbles a bit. This gives us seasons and the magnetic field that a compass detects.
What is working principle of synchros?
when rotor excited by ac voltage , the rotor current flow , and a magnetic field is produced .the rotor magnetic field induced an emf in the stator coils by transformer action.the effective voltage induced in any stator coildepend upon the angular position of te coil's axis w.r.t rotor axis sthitaprajna.rath@gmail.com
Role of stator and rotor in synchronous and induction motor?
Stator is part of rotating mechanical device thats sorrounds the rotor to rotate it through the induced magnetic field while the Rotor, is the one who is rotated by produced magnetic field in the stator,.
What is rotor in ac alternator?
A Rotor is a mechanism in the alternator that is driven by the pulley belt from the engine.which creates a magnetic field which causes voltage.Answer.The rotor does not 'create' a magnetic field. The emf induced in the stator winding is due to the residual magnetic flux of the rotor which cuts the stator windings as the rotor rotates.
Does induction motor has rotor winding?
Yes, the induction motor has a rotor winding. It is usually one turn, shorted. This is how the magnetic fields generated in the stator induce a current in the rotor, which subsequently generates a torque from the opposing magnetic fields, stator to rotor.
How energy is transferred from stator to rotor?
when current is passing through the stator windings of motor magnetic field is develop ,due to it emf is produced inside the stator windings,that emf is further cuts the emf across stator due to which current flowing inside the rotor.
What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
What type of motor has a stator?
An electric motor has a stator and a rotor. The stator does not move. The rotor rotates inside the stator.
What is the name principle of 3 phase induction motor?
Transformer action. There is no electrical connection between the stator and the rotor, and voltages get induced into the rotor bars when they are swept by lines of magnetic flux created by the stator windings.
What is the excitation of the generator?
The rotor must have a magnetic field in order to generator voltage in stator winding. The exciter circuit generates this DC filed in the rotor.
What are magnetic shading coils and what do they do in a magnetic motor Starter?
Shading coils provide a phase shift between the magnetic field of the rotor and stator, which is necessary to get the motor spinning.
List of steps in which an electric motor changes electrical energy to kinetic energy?
Briefly: 1. Current flows through the wires in the Stator and the Rotor. 2. A magnetic field is generated in the Stator and the Rotor, caused by the Current Flow. 3. Because of the design of the "Wire Windings" of the Stator and Rotor, there Magnetic Fields are OPPOSITE each other, and REPEL each other. 4. If the Magnetic Fields are strong enough to overcome FRICTION (and any LOAD attached to the Motor), the Rotor begins to turn. 5. The Speed (RPM) of the Motor is either regulated by its design, or the LOAD.
What is the Function of the rotor in an alternator?
This part forms the field circuit. It is a rotating part with a magnetic field that induces current into the stator
