Title:
MAGNETIZATION CONTROL METHOD OF ENGAGEMENT SYSTEM USING MAGNET
Document Type and Number:
Japanese Patent JP2016219465
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetization control method of an engagement system capable adjusting the magnetization state (attraction force) stably in a short time.SOLUTION: In a magnetization control method, a second permanent magnet 12, and an exciting coil 14 for magnetizing the second permanent magnet 12 are provided, magnetization state of the second permanent magnet 12 is changed by a magnetic field generated by applying a voltage to the exciting coil 14, and magnetization is ended in an area beyond the knick point of magnetic field-flux density curve of the second permanent magnet 12.SELECTED DRAWING: Figure 1
