Abstract [en]

This paper investigates the electrical machine, which is one of the important parts in the FreePiston Energy Converter (FPEC). In the previous work it was found that one of the best candidate suitablefor the FPEC is a Transverse Flux Machine (TFM) due to the very tough requirements on the electrical ma-chine such as a low weight of the translator (movable part in the machine).This paper presents a new conceptof a linear TFM in which strong emphasis has been put to achieve a design that is simple to manufacture.Different types of the magnet confgurations on the translator have been investigated. It has been found thatthe buried magnet design suffers from a very high leakage to the nearby poles and is thus not suitable forthis type of machine. Another confguration, which has been investigated, is the surface mounted magnetconfguration. Analytical models for this confguration have been established. It has been found that thetough requirements, 4kN from a 6kg movable mass, can be achieved at the required speed, specifc powerand effciency
