Design of a Rotary Transformer for Installations on Large Shafts

Rotary transformers are adopted to transfer energy from primary secondary in situations which the two sides relative rotation. These devices cylindrical with cores and corresponding winding separated by an air gap. Their employment became quite convenient availability of power electronics, allowing operation electrical systems at relatively high frequencies. In particular, this paper proposes design a light efficient transformer can be used applications involving large shafts. Moreover, sliced arrangement for magnetic core is proposed together experimental validation solution on reduced-size prototype.
