| Outline of Final Research Achievements |
The noise and vibration reduction of switched reluctance motor has been investigated for last several decades, however, the existing methods are limited. Three years ago, we have found a current waveform to reduce the acoustic noise effectively. The principle is simple, flattening the sum of three-phase radial forces. If stator yoke is rigid, then noise and vibration are reduced.
In this project, current waveform is generated considering up to 4th harmonic components and these phase shift to reduce the rms value of the current, so that efficiency is improved. A novel current waveform has been found to reduce the sum of radial forces.
