Abstract
Official abstract text for this publication.
The present invention includes a voltage applying step of applying an applied voltage including a DC component and a plurality of frequency components to a PM motor, a motor current detecting step of detecting a motor current flowing depending on the applied voltage, and a current control gain adjusting step of calculating a current control gain based on frequency characteristics of the applied voltage and the motor current. In this manner, a stable current control gain having a high current response can be adjusted within a short period of time.
First claim
Opening claim text (preview).
The invention claimed is: 1. A current control gain adjusting method for a PM motor comprising: a voltage applying step of applying to a PM motor a voltage command including a DC component and a plurality of frequency components; a motor current detecting step of detecting a responsive motor current flowing through the PM motor in response to application of the voltage command applied in the voltage applying step; a motor frequency characteristic determining step of calculatin…
