    摘要: A rotating electrical machine control device that applies a high frequency current to a rotating electrical machine including a rotor having saliency, estimates a magnetic pole direction of the rotor on the basis of a high frequency component contained in a voltage command as a response component to the high frequency current, and controls the rotating electrical machine. A high frequency superimposing section sets an estimated d-q axis rotating coordinate system, and a magnetic pole direction adjusting section sets a high frequency coordinate system having a phase difference of the high frequency current command with respect to the estimated d-q axis rotating coordinate system. A steady estimation error correcting section calculates a magnetic flux interference estimation error as an error of the estimated value of the magnetic pole direction which is caused by the d-q axis magnetic flux interference.

    摘要: A current detector that detects, based on output signals of N coreless current sensors, where N is a natural number of 3 or more, currents flowing in N conductors in a circuit connected so that the sum of the currents flowing in the N conductors becomes zero. The current detector has a signal-current correlation acquiring section that acquires a signal-current correlation representing a correlation between the output signals of the N coreless current sensors and the currents flowing in the N conductors. Furthermore, a current calculating section that calculates the currents flowing in the N conductors based on the output signals of all the N coreless current sensors by using the signal-current correlation.
