Electric Motor Lamination Steel

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.

Electric motor lamination steel.

Electric motor electric motor construction of induction motors. The mechanical properties of amorphous steel make stamping laminations for electric motors difficult. 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. Manufacturers may use silicon steel which primary includes steel combined with silicon.

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. The laminations are insulated from each other usually by a varnish layer. High speed presses ranging from 100 tons to 800 tons. These include electric motors generators and transformers.

Custom steel laminations represent over 50 of all sko die stampings. More detailed information about these two types of steels can be found in the metals handbook. 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.

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. Motor lamination steel is a specific cold rolled product tailored to create electromagnetic core materials for electrical equipment and components. Electric motor lamination stacks. Electrical steel laminations are constituent parts of every electric motor.

High precision stamping dies r bourgeois has invested in the world most accurate jig borer machine tool. The stator frame consists of laminations of silicon steel usually with a thickness of about 0 5 millimetre. Over 30 million press strokes per day allows output of over 300 tons finished magnetic circuits laminations each day. More about motor laminations electrical steel laminations may be used to create motor laminations.

Amorphous steel is limited to foils of about 50 µm thickness. This product group consists primarily of 006 029 low carbon and silicon alloy steels. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The steels used for these applications are designed to.
