Power-optimized symmetrizing current control with a 8.7 kNm-transverse flux generator

Tranverse flux machines (TFM) have been proposed as a powerful direct drive alternative. The construction and control of TFM have often proved a problem. In this paper the construction of a working transverse flux generator is presented. Its characteristics are predicted by a detailed FE simulation. Also a current control is designed that compensates unsymmetries and maximizes the power output. Measurements finish this work.
