Document Type and Number:
WIPO Patent Application WO/2023/234341
Kind Code:
A1
Abstract:
Provided is an easy-to-dismantle rotor-fixing resin composition used for forming a fixing member (130) of a rotor (100), which comprises: a rotor core (110) fixed to a rotating shaft and provided with a plurality of holes arranged along the circumference of the rotating shaft; a magnet (120) inserted into the hole (150); and the fixing member (130) provided in a space between the hole (150) and the magnet (120), the rotor fixing resin composition containing a thermosetting component, wherein a cured product obtained after thermosetting the rotor fixing resin composition has a structure represented by formula (1). wi="152.4"/> (In formula (1), R1 and R2 each independently represent a hydrogen atom, a C1-30 hydrocarbon group or aromatic group, a hydroxyl group, or a C1-30 alkoxyl group.)
