Title:
磁石の製造方法、及びロータの製造方法
Document Type and Number:
Japanese Patent JP7363700
Kind Code:
B2
Abstract:
A sheet-shaped insulating member including a thermoplastic resin fiber and an inorganic fiber is arranged on a surface of a magnet body. The insulating member is compressed while being heated to a temperature higher than or equal to a glass transition temperature of the thermoplastic resin fiber, so that the insulating member is thermocompression-bonded to the magnet body in a state in which the inorganic fiber is elastically compressed. A magnet is thus formed. With the magnet arranged in a slot of a rotor core, the magnet is heated to a temperature higher than or equal to the glass transition temperature of the thermoplastic resin fiber. This causes the inorganic fiber to restore elasticity, so that the magnet is fixed to the rotor core.
