Latest Patents

Fukusumi's latest patents include a Motor Controller and a Motor Abnormality Detecting Apparatus. The Motor Controller is a sophisticated control apparatus for electric motors. It features a current controller that provides multiphase voltage commands to a drive circuit for an inverter. This controller includes both a normal-mode current controller for standard operations and an abnormal-mode current controller for situations where abnormalities occur. In the event of an abnormality in one phase of the electric motor or the inverter, the controller adapts, generating multiphase voltage commands suitable for the inverter drive circuit.

The Motor Abnormality Detecting Apparatus is designed to identify abnormal conditions in a motor caused by disturbance voltage without requiring additional hardware. It estimates the disturbance voltage based on the target voltage and the actual current flowing through the motor. This apparatus includes a motor current detecting unit, a feedback controlling unit, an abnormal voltage estimating unit, and a motor abnormality judging unit. Together, these components work to assess the motor's condition and determine any abnormalities.
