In this study, the advantages of LIM used at low-speed
applications have been analysed. In the design process of
the LIM, the machine can be suitable for low-speed
operation without additional components of power
electronics with small structural changes. In the
investigated application example, performance of LIM is
analysed at low speed system whose pole pitch is
changed. The typical force versus speed characteristic
shows that there is a reasonable agreement between
theoretical and experimental results.
To increase the performance of LIM in low-speed
systems, it is necessary to minimise the parasitic air gap
at the bottom of the teeth where the steel sheets are
clamped and glued in to the yoke. In addition, to use
amorphous material for the yoke to solve the teeth
saturation problem is an efficient solution. But the using
of amorphous material is still under research stage
because of construction problems. The depth of slots for
taking in the steel sheets of the teeth has to be optimised
