A stator is the static part of rotary electromagnetic devices such as electric motors, alternators, and generators. It represents one of the two primary components of the device, the other being the moving rotor that supplies the working output.

Stator. The stator is a fixed part of the stationary motor. It consists of a stator housing (1), ball-bearings (2) that support the rotor (9), bearing blocks (3) for positioning of the bearings and as a finish for the stator housing, fan (4) for motor cooling and valve casing (5) as protection against the rotating fan.

Rotor is a related term of stator. Stator is a related term of rotor. As nouns the difference between stator and rotor is that stator is the stationary part of a motor or other machine while rotor is a rotating part of a mechanical device, for example in an electric motor, generator, alternator or pump.

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.

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.

The rotor currents in a cage winding produce a 3-phase magnetic field, which has the same number of poles as the stator field but is rotating at slip frequency with respect to the rotating rotor. If rotor current asymmetry occurs, then there will be a resultant backward (i.e., slower) rotating field at slip frequency with respect to the forward ...

Electromagnetic forces act between the rotor and stator when the rotor is performing eccentric motions with respect to the stator. The aim of this research was to study the charactarestics of the forces and develop the tools to calculate these forces accurately and as quickly as possible.

coils in the stator that create a rotating B field in the air gap between rotor and stator. ... rotor. The three-phase induction motor is the easiest motor of this type to understand so these notes start with that type. The single-phase induction motor is more subtle and less efficient. It is discussed later.

A rotor/stator rub is relatively easy to identify if the motor is disassembled. A less severe rotor/stator rub can slowly push iron from the rotor laminations over ventilation slots in the rotor.

LARGE STATOR/ROTOR ECCENTRICITY - A UNIT FAILURE CASE STUDY SUMMARY Large eccentricity between the stator and rotor was one of the main causes for a 120 MW, Kaplan turbine unit failure. The tangential keys detached from the rotor and damaged the stator core. The unit was

A three phase Induction motor mainly consists of two parts called as the Stator and the Rotor. The stator is the stationary part of the induction motor, and the rotor is the rotating part. The stator is the stationary part of the induction motor, and the rotor is the rotating part.

A turbine (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning "turbulence") is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.The work produced by a turbine can be used for generating electrical power when combined with a generator. A turbine is a turbomachine with at least one moving part called a rotor assembly ...

The operation of an induction motor is not possible with an unequal number of stator and rotor poles, and this type of rotor does not respond automatically to change in a number of stator poles. Hence the number of rotor poles must be made equal to the number of stator poles.
