摘　　要：通过对屏蔽电动机起动性能和惰行性能的研究,影响屏蔽电动机配套机械设备的功能,主要是在屏蔽电动机起动时,掌握了起动电流对时间的关系以及停止时的惰行曲线和惰行时间等相关问题。同时介绍了屏蔽电动机惰行时间的求法以及机械时间常数和阻力矩的求法。By researching starting performance and coasting drifting performances of the canned motor, it can be found that they can influence the function of matched mechanical e- quipment of the canned motor. The main point is to find out the relation between current and time during starting the canned motor, and relative problems of the coasting drifting curve and coasting drifting timed during stopping the canned motor. At the same time, the algorithms of coasting drifting time, resisting moment and mechanical time coefficient of the canned motor are introduced.

关 键 词：机械时间常数 阻力矩 惰行曲线 屏蔽电动机
