Title:
PERMANENT MAGNET FIELD, ROTATING MACHINE, LINEAR MOTOR, AND CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2023114101
Kind Code:
A
Abstract:
To provide a technology capable of more appropriately suppressing thermal demagnetization of a permanent magnet field.SOLUTION: A magnetic field 20 according to an embodiment of the present disclosure includes a permanent magnet 21 that generates a magnetic field for an armature 10, and a thermoelectric conversion element 23 attached to the permanent magnet 21. For example, the thermoelectric conversion element 23 is a magnetic thermoelectric conversion element that generates a voltage signal by a magneto-thermoelectric effect such as the anomalous Nernst effect or the spin Seebeck effect, and is attached to a surface different from the magnetic pole surface of the permanent magnet 21.SELECTED DRAWING: Figure 3
