Electric Motor Lamination Steel

Custom steel laminations represent over 50 of all sko die stampings.

Electric motor lamination steel.

Manufacturers may use silicon steel which primary includes steel combined with silicon. Motor lamination steel is a specific cold rolled product tailored to create electromagnetic core materials for electrical equipment and components. High precision stamping dies r bourgeois has invested in the world most accurate jig borer machine tool. Over 30 million press strokes per day allows output of over 300 tons finished magnetic circuits laminations each day.

Electrical steel laminations are constituent parts of every electric motor. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. Electric motor electric motor construction of induction motors. The stator frame consists of laminations of silicon steel usually with a thickness of about 0 5 millimetre.

More about motor laminations electrical steel laminations may be used to create motor laminations. We produce rotor and stator laminations and assembled stator and rotor stacks. They are produced in a rapid stamping process by forming electrical steel with a thickness of between 0 25 and 1 mm. There are two types of electrical steels used for rotor laminations semi processed and fully processed.

Our high speed tooling offers a low cost alternative to maufacturers with moderate to high volume stamping requirements. Few decisions in the design of an electric motor are as fundamental or have as far reaching consequences as the selection of the material to be used in the rotor or stator motor laminations which become lamination stacks. More detailed information about these two types of steels can be found in the metals handbook. This product group consists primarily of 006 029 low carbon and silicon alloy steels.

Cold rolled steel has been rolled at room temperature below its recrystallization temperature which enables better control over finished product shape thickness dimensions and surface finish. Since amorphous ribbon can be cast to any specific width under roughly 13 inches and can be sheared with relative ease it is a suitable material for wound electrical transformer cores. Amorphous steel is limited to foils of about 50 µm thickness. These include electric motors generators and transformers.

Cold rolled motor lamination sheet is a special type of cold rolled steel sheet product that is produced to maximize the performance of the products for use as electro magnetic core materials for electrical equipment components. Both are non oriented steel grades. The steels used for these applications are designed to. The mechanical properties of amorphous steel make stamping laminations for electric motors difficult.
