胶带输煤机制动力矩和逆止力矩分析

作者 陆家宁 《内蒙古电力》 1991年第3期41-45,共5页
胶带输煤机运行中通常应用两种力矩,即制动力矩和逆止力矩.制动力矩是使运行的胶带机停止,为克服惯性力矩而施加的一种力矩.一般来说这个力矩的大小是制动时间的函数.逆止力矩是指倾斜上运布置的胶带机停机后,为防止胶带及物料因下滑力... 胶带输煤机运行中通常应用两种力矩,即制动力矩和逆止力矩.制动力矩是使运行的胶带机停止,为克服惯性力矩而施加的一种力矩.一般来说这个力矩的大小是制动时间的函数.逆止力矩是指倾斜上运布置的胶带机停机后,为防止胶带及物料因下滑力的作用倒转,而需要施加的一种力矩.这个力矩与时间无关. 展开更多

A short review for the existing various driving methods for belt conveyor was given, which include the analysis and comparison about the advantages, disadvantages and suitable application range of these methods. Based on this the vari-able-frequency-control(VFC) method for belt conveyor drive was fully discussed with focus on its application in medium-high voltage range. The principle of Neutral Point Clamped (NPC) Three-Level Inverter using high-voltage IGBTs together with the control strategy of rotor field-oriented vector control for induction motor drive were illustrated. 展开更多
