摘要
直线电机作为电机驱动的一种,目前有很多的实现方式,电磁式的、压电式的和气动式直线电机或运动机构。本文根据电磁铁的往复运动特性,利用单向离合器的单向传递力矩,设计了一个往复冲击激励下的螺母直线电机。设计了电机的结构,分析了电机的运动过程和针对非线性碰撞利用MLP方法建立了简单的运动学方程,在搭建简单的实验平台后测量了三种不同质量铁芯冲击时丝杆的最大运动速度,并判断了电机运动的稳定性,得出在冲击激励下可以得到稳定的直线运动的结论。
As a kind of motor drive,linear motor has many ways to realize,such as electromagnetic,piezoelectric and pneumatic linear motor or motion mechanism.According to the reciprocating motion characteristics of electromagnet,a nut linear motor under reciprocating impact excitation is designed by using the one-way transmission torque of one-way clutch.The structure of the motor is designed,the motion process of the motor is analyzed,and a simple kinematics equation is established by MLP method for non-linear collision.After building a simple experimental platform,the maximum motion speed of the screw under impact of three different iron cores is measured,and the stability of the motor motion is judged.The conclusion that stable linear motion can be obtained under impact excitation is drawn.
