The present invention relates to a motor rotor comprising: a main body extending along a rotation axis of a motor, the main body being formed by a set of stacked sheets and being provided with fastener through holes; the end plates are arranged at the two ends of the main body in the direction of the rotation axis so as to clamp the group of stacked sheets between the end plates, and the end plates are provided with fastener mounting holes corresponding to the fastener through holes; a fastener extending through the fastener mounting holes of the end plates and the fastener through holes in the body to clamp the set of stacked sheets between the end plates; at least one end plate is provided with a glue inlet hole penetrating through the thickness of the end plate, and a fluid communication channel is arranged between the glue inlet hole and the fastener through hole to allow glue to flow into the fastener through hole from the outer side of the end plate through the glue inlet hole. The invention also relates to an electric machine comprising the electric machine rotor and a vehicle comprising the electric machine. The invention further relates to an assembling method of the motor rotor.

    本发明涉及一种电机转子,包括:主体,沿电机的旋转轴线延伸,该主体由一组堆叠的片形成且设置有紧固件通孔;端板,沿所述旋转轴线的方向设置在所述主体的两端以将所述一组堆叠的片夹持在所述端板之间,所述端板设置有与所述紧固件通孔相对应的紧固件安装孔;紧固件,延伸穿过所述端板的紧固件安装孔和所述主体中的紧固件通孔,以将所述一组堆叠的片夹持在所述端板之间;至少一个端板设置有贯穿该端板的厚度的胶水进入孔,所述胶水进入孔与所述紧固件通孔之间设置有流体连通通道以允许胶水从该端板外侧经由所述胶水进入孔流入所述紧固件通孔中。本发明还涉及包括所述电机转子的电机和包括电机的车辆。本发明进一步涉及一种电机转子的组装方法。
