CNC Ferrite Winding for Transformer and Inductor Cores in the Electrical Industry

Endicott Coil Company, Inc. manufactures premium ferrites for the electrical industry. Ferrites are used for producing transformer and inductor ferrite cores. Before ferrite cores, manufacturers faced power limitations due to the massive weight of traditional steel cores. When high frequency performance is needed, ferrites are smaller and have less eddy current loss than silicone steel laminations. Use of ferrite cores also reduces the amount of copper required because fewer turns are needed in the winding.

Endicott Coil produces ferrites in a variety of sizes and configurations with diameters up to approximately 2" with wire sizes ranging from 10 AWG- 48 AWG depending on the design. Available configurations include pot cores, toroids, E & I cores, ETD cores, and RM cores. Ferrites are produced according to the customer's specifications regarding direct current resistance, input/output voltage, inductance, impedance, and dielectric strength requirements. Ferrite cores are manufactured on our manual and CNC winding machines. Our products meet all applicable UL, CSA, and VDE codes and undergo dimensional inspection, HiPot testing, surge testing, exciting current testing, input & output voltage testing, and turn count as specified. For more information about our ferrites for the electrical industry, please see the table below or contact us directly.

Advantages  
  • ECC does not list maximum power as a limitation due to the common use of high frequency magnetics. In the past, power line frequency devices were usually limited by the maximum weight the factory could safely handle.
  • The high frequency magnetics utilize ferrite cores which weigh less than the silicon steel laminations used at power line frequency.
  • The high frequencies also reduce the weight of the copper windings due to the reduced number of turns required.
  • The laminations that would affect maximum power for high frequency magnetics would then be wire size and test frequency.
