Title:
電動機制御装置及び電動機制御方法
Document Type and Number:
Japanese Patent JP5791816
Kind Code:
B2
Abstract:
A current command generator (117) generates a current command that indicates a value of current supplied from an inverter circuit to electric motors connected in parallel with the inverter circuit. A voltage command calculator (120) generates a voltage compensation signal for compensating a difference between a value of actual current supplied to each of the electric motors and a value of current indicated by the current command. A determiner (135) determines, based on a value obtained from the voltage compensation signal, whether or not an abnormality is occurring in at least one of the electric motors. A shutdown controller (136) shuts down, upon the determiner (135) determining that an abnormality is occurring, the power supply from the inverter circuit to the each of the electric motors.
