    • PROBLEM TO BE SOLVED: To provide a resin composition for fixing a rotor which can achieve a rotor core having excellent long term reliability, even in an environment of rotating at high speed for a long time under high temperature.SOLUTION: The resin composition for fixing is used for formation of a fixing member 130 constituting a rotor 100 including a rotor core 110 provided with a hole 150, a magnet 120 inserted into the hole 150, and the fixing member 130 provided in a spacing part 140 between the hole 150 and the magnet 120, and contains a thermosetting resin (A), a hardener (B), and an inorganic filler (C). The resin composition for fixing is injection molded using a molding machine and a molding of the resin composition for fixing is prepared, and then the molding is hardened and immersed into ATF. When the weight of the hardened matter before immersion into ATF is X1, and the weight of the hardened matter after immersion into ATF is X2, weight change rate calculated by (X2-X1)/X1×100 is -0.05% or greater and 0.5% or less.
    • 要解决的问题:提供一种用于固定转子的树脂组合物,即使在高温下长时间高速旋转的环境中也能实现具有优异的长期可靠性的转子铁心的转子。解决方案:用于固定的树脂组合物 用于形成构成转子100的固定构件130,转子100包括设置有孔150的转子芯110,插入孔150中的磁体120和设置在孔150和孔150之间的间隔部140中的固定构件130。 磁体120,并含有热固性树脂(A),硬化剂(B)和无机填料(C)。 使用成型机注塑成型树脂组合物,制备用于固定的树脂组合物的模塑件,然后将模塑件硬化并浸入ATF中。 当浸入ATF中的硬化物质的重量为X1时,浸入ATF中的硬化物的重量为X2,由(X2-X1)/ X1×100计算出的重量变化率为-0.05%以上,0.5 % 或更少。
