| Outline of Final Research Achievements |
The purpose of this research was to build a "high-speed building factor evaluation system" and to develop a "stator core excitation method" that can accurately evaluate the iron loss of the stator core. As a result, a "high-speed building factor evaluation system" equipped with a high-speed AD / DA converter for evaluating the stator core of a motor used in a wide speed range was constructed. By incorporating a general-purpose PWM inverter in this system, it was possible to evaluate the stator core under PWM excitation. Furthermore, the circuit was devised and an initial trial production of a dedicated PWM inverter was performed. We also developed the "winding excitation method" as a stator excitation method that can be applied to stator cores with many different specifications.
