摘　　要：分析一种采用无固定端的轴承支承结构的直线步进电动机,更改为固定端的结构,对比两种电机轴承额定寿命曲线、电机轴向力与位移曲线等数据,验证拥有固定端结构的直线步进电动机在双向轴向刚度、定位稳定性及额定寿命上有提升。A kind of traditional linear stepper motor with no-fixed end bearing support structure was analyzed,and a new motor with fixed end bearing structure was proposed.Through comparison with the traditional motor in bearing rating life curve and the axial force-deformation curve,the motor with fixed end bearing structure has better bidirectional axial stiffness,stability and rating life.

关 键 词：直线步进电动机 轴向刚度 定位稳定性 寿命
