| Abstract |
Electrical machine is one of the key parts in the
Free Piston Energy Converter (FPEC). In previous work it was
found that one of the best candidates suitable for the FPEC
is a Transverse Flux Machine (TFM) due to the very tough
requirements on the electrical machine such as low weight of the
translator (movable part in the machine). This paper presents
a novel concept of linear TFM in which strong emphasis has
been put on achieving a design that is simple to manufacture.
Different types of magnet configurations on the translator have
been investigated. It has been found that the buried magnet
design suffers from a very high leakage to the nearby poles and is
thus not suitable for this type of machine. Another configuration
which has been investigated is the surface mounted magnet
configuration. Analytical models for this configuration have been
established. It has been found that the hard requirements, 4kN
from a 6kg movable mass, can be achieved at the required speed,
specific power and efficiency. |
