最近20年,中速范围电梯的驱动技术引起了电梯行业的注意。但在竞争者中近几年大多数是采用与老的驱动系统差不多相似的技术,没有太大的突破,所以在这方面改进不大。而目前市场对低中速电梯的要求是增加舒适感;降低能量损耗;使用惯量小的系统;实现短楼层距离的运行和最佳的行驶曲线。瑞士迅达交流调速Dynatran-S(简称DS)电梯的推出,使低中速电梯的驱动性能达到了上述几方面的要求。 In the last 20 years, the drive technology of elevators in the medium-speed range has attracted the attention of the elevator industry. However, most of the competitors in recent years have adopted technologies that are almost similar to those of the old drive system. There has been no major breakthrough, so there is little improvement in this area. The current market demand for low-to-medium-speed elevators is to increase comfort; reduce energy consumption; use a system with small inertia; achieve short-distance distance operation and optimal driving curve. The launch of the Swiss Schindler AC speed-adjustable Dynatran-S (DS) elevator has enabled the drive performance of low-to-medium speed elevators to meet the above requirements.
