Title:
ROTATING ELECTRIC MACHINE LOAD DETECTION DEVICE AND INTERPOSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/208579
Kind Code:
A1
Abstract:
This rotating electric machine load detection device is provided with: a pulse output means for outputting a pulse signal (P) synchronized to the rotation of a rotating shaft; a current change measuring means for comparing, on the basis of the pulse signal (P), the values of currents having the same positional relationship in one rotation of the rotating shaft with each other, thereby measuring the amount of change (ΔI1) between the values of currents; and a load detection means for calculating the load of a rotating electric machine using the measured amount of change (ΔI1) between the values of currents.
