Abstract
Official abstract text for this publication.
A three-phase AC motor ( 4 ) has a configuration in which a q-axis inductance is larger than a d-axis inductance by a predetermined amount or more to allow smoothing of power fluctuations due to the power supply voltage of the AC power source ( 3 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor which is driven and controlled by a power conversion device including a converter section configured to rectify AC power of an AC power source, an inverter section including a plurality of switching elements and configured to perform switching operations of the switching elements to convert output power of the converter section into AC power at a predetermined frequency, and a capacitor provided in an output side of the converter section and hav…
