Laminated Steel Transformers and Inductors

transformersLaminated steel transformers and inductors have a core formed by stacking thin steel sheets or laminations. These laminations are frequently in the shape of "E"s and "I"s, hence the common term "EI" lamination. Copper wire is wound into the form of coils, each having one or more windings. The core is stacked through the coil to form the complete transformer or inductor. These devices can be supplied for both single and three phase applications. Inductors are useful in both a-c and d-c circuits.

Advantages

  • Available in both smaller and larger sizes than toroid designs
  • Easily gapped for inductor applications
  • Suitable for high voltage and high current applications

Typical Applications

  • Power supplies
  • Battery chargers
  • Inverters
  • Ac filter inductors (reactors)
  • Dc smoothing inductors (chokes)
  • Autotransformers
  • Isolation transformers

Ratings and Sizes

All of General’s products are custom designed for specific applications. Available ratings depend upon a number of factors including power requirements, maximum voltages, currents, and frequency. We can produce laminated steel isolation transformers with ratings from 100 va to 60 kva for 50/60 Hz, operation, autotransformers to 120 kva, and transformers for 400 Hz operation to 20 kva or more. Please do not hesitate to inquire as to your requirements.
