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,.
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 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.
Why induction motor is called asynchronous motor?
as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torque. so since the rotor runs with a speed other than the synchronous speed of rotating magnetic field produced by stator current so it is called as asynchronous motor.. asynchronous -means not moving with synchronous speed --------------------mrityunjay (kiit university . b.tech 2nd year student)
What does a Rotating magnetic field do?
The Field which is continuously rotating with a particular axis is known as rotating magnetic field. It will be created in Three phase induction motor's stator. When the supply is given to stator of three induction motor, the flux of each phases (that are displaced by 120 degrees) will interact. Due to this the resultant Field will be rotating Magnetic Field will be Produced.
Why are stator cores laminated?
Thin metal laminations are used to minimize the magnetic flux eddy current loss in the stator cores of high-speed, high-performance induction motors.
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 function of a stator in alternator?
The stator is the stationary winding assembly that makes the magnetic field inside the alternator. It is this magnetic field that the armature rotates in generating the electricity.
What does a stator do on an alternator?
The stator on an alternator is used to generate a magnetic field. This is a large factor in the production of electricity.
What does the magnetic field in an alternator rotate around?
Stator
What part of the ac generator produces the rotating magnetic field?
The stator and the magnets.
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 is stator of the armature?
The 'stator' is the generic term for the stationary parts of a machine, including its frame, magnetic circuit, poles, windings, etc.
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.
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.
Why induction motor is called asynchronous motor?
as we know that a rotating magnetic field is created by the satator current,and so in the rotor there is induced current and there by the rotor developes a unidirectional torque. so since the rotor runs with a speed other than the synchronous speed of rotating magnetic field produced by stator current so it is called as asynchronous motor.. asynchronous -means not moving with synchronous speed --------------------mrityunjay (kiit university . b.tech 2nd year student)
