Title:
MAGNETIZATION ESTIMATION DEVICE, MAGNETIZATION ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/080260
Kind Code:
A1
Abstract:
A magnetization estimation device 10 estimates the state of magnetization of a permanent magnet 24 loaded in a magnetic material. The magnetization estimation device 10 comprises a measurement unit 11 that measures leakage flux generated from the permanent magnet 24 and a control unit 14 that estimates the state of magnetization of the permanent magnet 24 at the time when leakage flux is generated using a magnetization estimation algorithm on the basis of the leakage flux measured by the measurement unit 11.
