Materials
Our company utilizes high-quality cold-rolled grain-oriented and non-oriented silicon steel materials—available in thicknesses of 0.05mm, 0.08mm, 0.10mm, 0.23mm, 0.27mm, 0.30mm, and 0.35mm—characterized by low iron loss and high magnetic permeability.
Structural Features
The core features an open-type structure formed by the assembly of two halves into a closed magnetic circuit. Consequently, the windings can be manufactured independently of the core and subsequently fitted onto it, thereby significantly shortening the overall production lead time.
Applications
Available in various specifications, these E-cores are widely utilized in electronic and electrical equipment as core components for three-phase transformers, reactors, chokes, and other electromagnetic devices.
Specifications
Products can be customized in accordance with national standards or specific client requirements, ensuring that the diverse needs of customers at all levels are fully met.
Cut laminations are a crucial component in the manufacturing of electrical machines and transformers. They consist of thin sheets of magnetic material, typically silicon steel or other specialized alloys, stacked together to form the core of these devices. The term "cut" refers to the process of shaping these laminations into specific geometries to meet design requirements. The primary purpose of cut laminations is to reduce eddy current losses within the core, which occur when a changing magnetic field induces circulating currents in conductive materials. By using thin, insulated layers, the path for these currents is limited, significantly improving the overall efficiency of the device. Cut laminations come in various shapes and sizes, including E-I, U-I, and toroidal configurations.
The cutting process can be achieved through several methods, such as stamping, laser cutting, or wire electrical discharge machining (EDM). Each method offers different advantages in terms of precision, cost, and production volume. The thickness of individual laminations typically ranges from 0.1 to 0.5 mm, with thinner sheets generally providing better performance but at a higher cost. The laminations are often coated with insulating materials to further reduce inter-laminar eddy currents.In addition to their use in transformers and motors, cut laminations find applications in inductors, generators, and other electromagnetic devices across various industries, including automotive, renewable energy, and consumer electronics.
