What are stator lamination made of.
Laminated stators are a no brainer when it comes to core construction.
In layman s terms laminating the stators makes the motor more efficient.
Laminations sheets are used instead of a solid pice to reduce eddy current losses.
Laminations sotek specializes in electrical steel laminations stacked stator core rotor core assembly manufacturing for motors and generators.
Laminations are the steel portions of the stator and rotor consisting of thin lamination sheets stacked together.
Electrical steel also called lamination steel silicon electrical steel silicon steel relay steel or transformer steel is specialty steel tailored to produce certain magnetic properties such as a small hysteresis area small.
The structure of a variable rm is quite simple.
They are produced in a rapid stamping process by forming electrical steel with a thickness of between 0 25 and 1 mm.
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 particular it consists of a stator with salient poles made of magnetic lamination sheets and a rotor with salient poles which is in most cases also made from conventional magnetic lamination sheets.
The laminations are basically round with a round hole inside through which the rotor is positioned.
Where ever a coil is involved there will certainly be eddy current loss because of variation of magnetic field an e m f will be induced giving rise to current which does not contribute to the load rather gets wasted in the periphery of the coi.
In an electric motor the stator provides a rotating magnetic field that drives the rotating armature.
These laminations can be stacked loose welded or bonded together depending on your application.

As of now laminations are created by computer controlled laser cutting machines or stamping punching dies.

What is a lamination.
Electrical steel laminations are constituent parts of every electric motor.
The inner surface of the stator is made up of a number of deep slots or grooves around the stator.
Lamination plates have narrow hysteresis loops requiring less energy to magnetize and demagnetize the core.
We produce rotor and stator laminations and assembled stator and rotor stacks.
Modern laminations are comprised of silica steel cold rolled and grain.
A typical stator core is made up of countless individual steel laminations from thousands up to even hundreds of thousands.
