交流变频调速技术是20世纪80年代发展起来的,在90年代获得了飞速发展,技术日益成熟,甚至有人预言,21世纪将是交流调速一统天下的时代。以直流驱动产品为先导的中国雪普正是在这个大背景下成立的。直流传动产品在21世纪将扮演什么样的角色,交流调速能否取代直流调速技术,带着这 AC variable frequency speed control technology developed in the 1980s, gained rapid development in the 1990s, the technology is increasingly mature, and some even predicted that the 21st century will be the era of exchange and speed control. It is in this background that China Xuepeng, which is driven by DC drive products, was established. DC transmission products in the 21st century will play what kind of role, AC speed control can replace the DC speed control technology, with this
