| Abstract |
Recent developments of power electronics
technology, low-loss iron core materials and highly efficient
permanent magnet, etc have made it possible to realize a
small size, high or ultra-high speed, and high performance
electrical drive system. We designed and built a trial ultrahigh
speed drive system of 2 poles, 5kW, 240,000rpm and
had described our prototype system and showed some
experimental results in the previous paper. This kind of
motor is supported to development of various technology,
such as control technology including DSP, FPGA, etc.,
power conversion technology and design technology which
includes a finite element method. The development as a
comprehensive drive system is necessary. In this paper we
describe the coupled analysis model which is represented
for entire drive system. This model was used to evaluate the
fundamental motor characteristics at the first of design
stage. And the model also has been applied to total
systematic approach to enhance the total drive system. |
