The affected core area is removed by cutting, sanding and straightening the laminations. Usually such a repair is followed by an EL CID test to determine if a short between laminations remains. If the stator
Stator
The stator is the stationary part of a rotary system, found in electric generators, electric motors, sirens, mud motors or biological rotors. Energy flows through a stator to or from the rotating component of the system. In an electric motor, the stator provides a rotating magnetic field that driv…

What spins the rotor in a generator?
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.
What does a rotor do in a generator?
The rotor, acting as the armature, rotates in the field, cutting the lines of force and producing the desired output voltage. The output voltage is taken from the rotor by the slip rings and brushes.

How do I test my rotors?
To perform a high current rotor test, you remove the rotor from the stator and apply a high current through the shaft of the rotor. Then an infrared camera will allow you to visually inspect the surface of the rotor for localized hot spots. Those localized hot spots reveal problems with the rotor bar.
Is rotor and armature the same?
In a generator and a motor, a rotor rotates and the stationary part of the motor is known as a stator. Similarly an armature carries current while field windings produce the magnetic field needed to excite the generator and the motor.
What is rotor and stator?
The rotor is the rotating part of a machine. In electrical motors or generators, the whole linear synchronously rotating part of the machine is termed the rotor. The stator is the non-moving, fixed counterpart in a machine.

What is armature in generator?
The armature is an integral part of the motor (or generator), as this is the component that carries the alternating current (AC) in an electric machine. The armature conducts AC, even on Direct Current (DC) machines using the commutator (which reverses current direction every so often) or due to electronic commutation.
What can damage a generator coil?
Generator Protection: 7 Things that Wreck Your GeneratorFaults. A fault is any unwanted electrical current flow. ... Overload. ... Overheating (Windings or Bearings) ... Overspeed. ... Loss of Excitation. ... Motoring. ... Unbalanced Current Operation.
Why is my generator running but not producing power?
Loss of residual magnetism may be caused by the generation being out of use for a while, having a connected load when the generator is shut off, running your generator for too long with no load, or if your generator is new, it could have lost residual magnetism from long distance transportation vibration.
Why do generator coils burn?
Improper match between the electrical source and the coil rating is sometimes a cause for coil burn-out: Voltage Too High. The operating voltage should not be more than 10% higher than the coil voltage rating. Excessive voltage causes excessive coil current which overheats the coil.
Whats is a rotor?
Definition of rotor 1a : a part that revolves in a stationary part a brake rotor. b : the rotating member of an electrical machine. 2 : an assembly of rotating blades that supplies lift or stability for a rotorcraft.
What is a rotor in a motor?
The rotor is located inside the stator and is mounted on the AC motor's shaft. The term "rotor" is derived from the word rotating. The rotor then is the rotating part of the AC motor. The objective of these motor components is to make the rotor rotate which in turn will rotate the motor shaft.
What is the stator and rotor?
The rotor is the rotating part of a machine. In electrical motors or generators, the whole linear synchronously rotating part of the machine is termed the rotor. The stator is the non-moving, fixed counterpart in a machine.
What is rotor in diesel generator?
The rotor also known as the armature is the movable part of the alternator that produces the rotating magnetic field in three different ways. Induction – You have this mechanism in large generators. You also know them by the name 'brushless generators. '
What are the problems with generator rotors?
The mostcommon problems occurring with generatorrotors are shorted turns and breakdown ingroundwall insulation. These two concerns willbe discussed in detail.
Is hydrogen cooled generator well sealed?
A hydrogen-cooled generator is well sealed and should seevery little contamination. A TEWAC (totallyenclosed water to air cooled) unit will requiresmall amounts of make-up air that can intro-duce particulates into the generator. An OV(open ventilated) generator is most likely to seelarge amounts of contamination introducedinto the field.
Can you repair an existing rotor?
It is often possible to repair/refurbish an exist-ing rotor to satisfactory working condition.However, in certain circumstances, it maybecome necessary to replace the existing rotor.The following situations are instances whenreplacement is preferable to repair:
