Abstract

Electrical power generation employing wave energy converters (WECs) incorporating linear generators (LGs) made of traditional steel core material results in large amount of core loss. In this context, a new direct drive linear generator (DDLG) with reduced core loss is designed using high grade magnetic cores. The numerical model of the designed LG is introduced in an explicable way. The simulation task is carried out in ANSYS/Maxwell software environment with DI-MAX HF-12, DI-MAX HF-10, and typical iron as the core materials. Analyzed results of electrical output parameters as well as magnetic properties such as transient magnetic flux density, magnetic flux intensity and the most expected core loss are demonstrated. Analysis greatly contributes to select the high grade Armco DI-MAX HF-12 as the core material for the proposed DDLG as it causes low core loss compared to that of traditional iron one. It is recommended that the analysis of core material for DDLGs will play vital role in future developments of LGs.
