直至目前为止,生产能力较大的竖井提升机几乎全部采用直流电动机驱动。由于现代调节技术以及电子控制和监视装置的发展,直流驱动装置业已达到很高的技术水平,而且安全可靠。为使提升机生产运行更加安全可靠,维护量最小,不断提高驱动功率,以及近年来能源费用急剧上涨等多方面的原因,促使人们寻求其它可能的驱动技术。自控式变频器供电的交流电动机与新型定向励磁的旋转矢
Until now, almost all of the shaft hoists with larger capacities have been driven by DC motors. Due to the modern regulation technology and the development of electronic control and monitoring devices, DC drives have reached a very high level of technology and are safe and reliable. In order to make the lift more safe and reliable production operations, the maintenance of the smallest, continuously improve the drive power, and the sharp rise in energy costs in recent years and many other reasons, prompting people to seek other possible drive technology.
