Abstract
This paper presents a general proposal to design and calculate the performance of a tubular permanent magnet linear generator using the Finite Element Method. The cogging force, which occurs due to the interaction between stator teeth and the permanent magnets, is reduced by optimizing the linear generator dimensions. The generated voltage is analyzed for both no load and load cases to take the armature reaction efsects on the air gap flux density. A repetitive routine is followed to calculate the output voltage from the change offlux and the speed of the generator. The output voltage is calculated for dferent resistive load, and hence the generator load characteristic is obtained. The designed linear generator is capable to generate an output power of 5.3kW with output voltage of 222V and the generator eficiency of 96.8%.
