Outline of Final Research Achievements

We have developed a control technology for small, highly efficient permanent magnet synchronous motors that can be started immediately after wiring without prior adjustment work, and verified it through experiments. This was achieved by using the start-up sequence of a permanent magnet synchronous motor driven without a rotational position sensor, and by executing current sampling at a shorter cycle than conventional control processing, and by executing parameter measurement.
