Abstract
In this paper, a 6-phase permanent-magnet flux-reversal linear machine for low-speed reciprocating power generation is presented. By increasing the phase number, the phase current is reduced for the same rated power which results in a lower ohmic loss. In addition, the thrust force ripple can be reduced accordingly. By borrowing the transverse-flux concept, the electric loading and the magnetic loading is decoupled and the thrust density can be improved accordingly. The stator of the proposed machine adopts the modular design, and each phase is magnetically decoupled with each other which gives more flexibility and controllability of the generator. Based on the same topology, the proposed machine can be extended to a machine with an arbitrary number of phase to suit different applications.published_or_final_versio
