为了简化平衡头的自锁结构,提出一种磁路自锁型电磁-永磁混合式平衡头。当线圈不通电时,依靠相邻两个永磁体与磁性内齿盘之间的磁阻最小,平衡头锁定在稳定位置。当线圈通电后,在电磁场和永磁体作用下,平衡头启动并向下一稳定位置运动。讨论了影响平衡头自锁力矩和启动力矩的结构参数,并对各个参数的取值范围进行了初步设计。通过有限元电磁分析,得到了其与自锁力矩、启动力矩之间的量化关系。基于此,设计并开发了一套电磁平衡头样机,完成了其自锁可靠性计算和启动能力试验。对比计算和试验结果,平衡头结构设计和参数选取正确。研究工作为该平衡头的工程应用提供了重要的参考价值。

In order to simplify a balancer's self-locking structure,a magnetic balancer getting a self-locking state by designing a magnetic circuit was proposed.It's true that when a coil is not turned on,there is a minimum magnetic resistance between two adjacent permanent magnets and magnetic toothed discs,so a balancer can be locked at a stable position;when the coil is turned on,the balancer starts and then moves to the next stable position under the interaction of electromagnetic fields and permanent magnets.The structural parameters of a balancer affecting its self-locking torque and starting one were discussed,and these parameters' ranges were roughly designed.With finite element electromagnetic analysis,the quantitative relationships among these parameters and self-locking torque and starting one were obtained. Based on the above results,the design and development of a magnetic balancer prototype were completed.Its self-locking reliability calculation and starting capability test were accomplished.Comparing calculation and test results showed that the structural design and parameter selection of the developed balancer are correct.This study provided an important reference for engineering applications of the proposed balancer.
