Title:
METHOD FOR MANUFACTURING BONDED MAGNET AND METHOD FOR MANUFACTURING MAGNETIC DEVICE HAVING BONDED MAGNET
Document Type and Number:
WIPO Patent Application WO/2004/027795
Kind Code:
A1
Abstract:
A viscous body (4) is prepared by mixing a magnetic alloy powder, which has been magnetized in advance, with a resin. The viscous body (4) is applied to the upper surface of the center magnetic leg of an E-shaped core (2). A coil (3) and I-shaped core are put together with the E-shape core (2), and the resin is cured while applying an orientation magnetic field by using a permanent magnet (5). Accordingly, there is obtained a bonded magnet closely adhered to the opposed faces of the E-shape core (2) and the I-shape core, which faces are opposed to each other, thereby forming a magnetic gap.
