Tubular Permanent Magnet Linear Synchronous Generator forWave-power Generation

In this paper tubular type slotless Permanent Magnet Linear Synchronous Generator (PMLSG), which produces neitherthe detent force nor normal force is proposed for wave power generator. The characteristics of the stator configurationare estimated using the Finite Element (FE) analysis and the relation between the output and loss characteristics withpole pitch is examined. Moreover, the operating performance of the generator is analyzed under the no-load and loadswith variable resistance. In the generator performance with variable resistance load, while the load increases, thecharacteristics of the induced voltage and load current are investigated and the efficiency is also defined from thecomparison between electrical output (induced voltage and load current) and mechanical input (external force) in eachload.
