本文对《电磁旋转隔离机构的计算和分析》一文,就其论证的最小电磁力矩M_(min)及电磁力矩M随转角α的变化规律,提几点看法。从基本电磁理论进行分析,电磁转矩的最小值M_(min)应为零,衔铁在磁场中旋转一周的电磁力矩应是一周期函数,并提出衔铁选用阿基米德螺旋线的目的是从提高安全性能出发的。 This article on the “electromagnetic rotation isolation mechanism calculation and analysis,” a paper on its demonstration of the minimum electromagnetic torque M_ (min) and the electromagnetic torque M with angle α variation, make a few comments. From the basic electromagnetic theory analysis, the minimum value of electromagnetic torque M_ (min) should be zero, the armature rotating in the magnetic field for a week should be a period of electromagnetic torque, and put forward the choice of Archimedean armature spiral purpose is Improve safety performance starting.
