Abstract: The aim of the present study is to develop a motor-generator that
fits into a microturbine generator (MTG) system with a power density of 500 W
class considering the DC load. The performance evaluation of the
motor-generator is performed by back-to-back tests according to AC and DC load
to evaluate the power generating characteristics. The power generating
characteristics simulation is compared with the experimental results. The
analysis results are in accord with the experiment results considering AC and
DC loads. The slot model is determined by several characteristics, such as size
constraint and the mechanical and electrical performance results between slot
and slotless models.
