Özet
The efficiency and magnetic saturation performances of the 3D printed magnetic composite cores are currently a bit far from competing with silicon steel in traditional motor topologies and transformer applications. However, the flexibility provided in 3D design and the rapid advancement in the production technologies are rapidly reducing the gap between these performances. Linear V-I characteristics can be obtained in the 3D printing magnetic cores using the filaments produced by mixing magnetic powders such as Iron, Nickel, Cobalt with polymer in different ratios. This makes them suitable for the Rogowski Coil (RC) applications. RCs are required to have linear V-I characteristics in order to measure low and high currents with the same sensitivity in the defined current measurement range. In this paper, nickel-filled filaments produced by mixing nickel and polymer in different ratios were used for the production of flexible RC cores. The V-I characteristics of RCs produced using 40% and 60% nickel-filled filaments and air-core RC have been modeled using the linear regression analysis. The success of the mathematical models has also been tested with four different error analyses. The proven mathematical models of the RCs will provide new inspiration to the researchers for magnetic applications. Optimal RC designs can be investigated using the mathematical models in the Finite Element Analysis (FEA) package programs.
