Why are all cores exposed to ac flux variation laminated?
Limit effects (heat loss) caused by eddy currents
Cr 125 stator ohms?
Looking for coil ohms and stator ohms. And possibly the voltage comming out of the stator .
What is stater and rotar?
A stator is the stationary part of an electric motor. The stator contains the windings in which the electrical source is connected to. The rotar is the core and shaft that rotates when electricity is applied to the stator
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.
Why the core is laminated in TF?

Why the stator is not laminated in DC machines?
The stator is not laminated in DC machines because it does not need to be laminated. Lamination is used in AC machines to prevent eddy currents from generating excess power due to the transformer effect of having a one-turn secondary that is short circuited. There is more to it than just the laminations - the laminations are insulated from each other, and interleaved, so that they have poor electrical connection while having good magnetic coupling.

Why electricity does not flow through iron core of transformer?
It does. We call this current, or currents, 'eddy currents', and they are minimised by using laminated cores.
What has the author D J Finch written?
D J. Finch has written: 'Vibration and noise response of electrical machine stator cores'
What is auto transformer stater?
I think you are confusing your terms. The term 'stator' (not 'stater') is used to describe the stationary part of a rotating machine (motor, generator), as opposed to the term 'rotor' which describes the rotating part. No part of an autotransformer is normally described as a 'stator'. An autotransformer has a laminated silicon-steel 'core', around which are placed 'windings'.
Why you use only iron core in transformers?
iron has high permeabiliy than others and also less leakageAnswerGenerally speaking, transformer cores are manufactured from laminated sheets of silicon steel, not iron.
Hetropolar field winding in dc machines?
a common magnetic flux crosses the air gab from stator to rotor cores causing in the production of north and south poles in the air gab between them
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.
Can laminated glass be tempered?
Tempered glass can be laminated, but laminated glass cannot be tempered.
What is density of laminated glass?
density of laminated glass
Cr 125 stator ohms?
Looking for coil ohms and stator ohms. And possibly the voltage comming out of the stator .
What is LVL?
Laminated veneer lumber (LVL) is a material made of thick veneers laminated along the grain direction, hot pressed and glued, and then sawed. Compared with solid wood, LVL has the advantages of uniform structure, high strength and good dimensional stability, which can meet the application requirements of wood structure building, bridge, furniture and transportation. Main species: Masson pine laminated veneer, eucalyptus laminated veneer, Yunnan pine laminated veneer, Larch laminated veneer, poplar laminated veneer, bamboo bundle laminated veneer, bamboo and wood composite laminated veneer.
