Compact regenerative elevator drive with one unique power module

Abstract:
The trend that small cities have been growing up into great cities or metropolises seems inevitable. It will challenge us in many aspects such as energy supply, environmental improvement and pollution control, so energy saving and emission reduction has been put into an even important position. Technology innovation and development are injecting new impetus and providing us new thoughts in city management and construction. Elevator as high electricity consumption equipment is a necessity in our daily life of city, so, under this background, more and more elevator companies are paying attention to energy regenerative technology. Drive as heart of elevator associates with the whole system’s reliability, lifetime and electricity performance, which are always supposed to be improved, but any improvement should also be cost efficient because of increasing strong market competition.
