The invention belongs to the technical field of motor driving, and discloses a variable stiffness adjusting method of a motor mount, the motor mount comprises a rigid structure body and an elastic body borne in the rigid structure body, and a variable stiffness adjusting groove is longitudinally arranged close to the opening end of the inner wall of the rigid structure body; the variable stiffness adjusting groove provides transverse and vertical deformation spaces for an elastic body of the motor suspension; when the elastic body is subjected to vertical acting force, the elastic body adjusts the vertical rigidity and the transverse rigidity of the motor suspension through the supporting effect of the rigid structural body and the position limiting effect of the adjusting groove. The use and structural characteristics of a product are comprehensively considered, the motor suspension is divided into three parts, the stop part, the mounting part and the bearing part are combined, the variable-stiffness adjusting groove is formed in the stop part, and a space for stiffness deformation is provided for an elastic body of the motor suspension when the elastic body is stressed.

    本发明属于电机驱动技术领域,公开了一种电机悬置的变刚度调节方法,所述电机悬置包括刚性结构体和承载在刚性结构体内部的弹性体,靠近所述刚性结构体内壁的开口端,纵向设置有变刚度调节槽;所述变刚度调节槽给电机悬置的弹性体提供横向和垂向的变形空间;在弹性体受到垂向作用力时,弹性体通过刚性结构体的支撑作用和调节槽的位置限定作用,来调节电机悬置的垂向和横向刚度。通过全面考虑产品的使用和结构特性,将电机悬置设置为三部分,通过止挡部、安装部和承载部相结合,将止挡部处设置变刚度调节槽,给电机悬置的弹性体在受力时提供了刚度变形量的空间。
