The application scope of silicon steel EI lamination
Dec 10, 2018

The silicon steel EI lamination has good magnetic properties, which can greatly improve the self-inductance coefficient of the ballast. It generates a high self-induced electromotive force at the moment of the light and the switching point, so that the high-voltage excitation of the lamp and the normal light. The silicon steel EI lamination are widely used, respectively, using directional silicon steel sheets. The military electronics industry is an important soft magnetic material, mainly used for high-frequency transformers; in addition to the use of hot-rolled silicon steel, hot-rolled electrical steel is mainly used for some micro-motors.

The silicon steel EI lamination are often used as high-speed, high-efficiency motor and generator laminations. Ordinary laminations use 0.014 to 0.032 thickness, and some are thinner. They are used in a rotating or fixed design depending on the laminate structure or in the stator. The laminations are generally circular and the magnetism is equal in all directions.

Non-oriented silicon steel EI lamination are best suited for high frequency motors and generators above 400 Hz, where the use of thinner materials counteracts the inefficient effects of increased eddy currents and subsequent heat buildup, which can be produced using thin laminates A more efficient unit and release design constraints by allowing the motor to be completely enclosed without external cooling.
