1可变速电梯原理与称重装置的重要性分析可变速电梯[1]是一种新型电力驱动曳引式电梯,这种新型电梯是利用轿厢与对重两侧的重量之差较小时,电梯的驱动电动机有富裕的能力而实现电梯的高速运行,这样电梯的运行速度就能随载荷变化而在额定速度及数个中间负载额定速度之间切换。可见载荷 A variable-speed elevator principle and weighing device importance analysis Variable-speed elevator [1] is a new type of electric traction traction elevator, the new elevator is the use of the weight of the car and the weight on both sides of the smaller, The drive motor of the elevator has the wealth of ability to realize the high speed operation of the elevator so that the elevator operating speed can be switched between the rated speed and several intermediate load rated speeds as the load changes.
