近几年随着电子技术、微电子技术、控制技术、网络化技术的高速发展,交流变频调速技术发展十分迅速,其性能也胜过其他任何一种交流调速(如降压调速、滑差调速、液力偶合器等)方式,且结构简单,稳定可靠,调速范围广,节能显著。尤其是最近高压变频器的飞速发展,让高压电机高性能地调速变为现实。目前高压变频器大部分应用于风机、泵类的应用领域,而在胶带输送机上应用很少。 In recent years, with the rapid development of electronic technology, microelectronics technology, control technology and networked technology, AC variable frequency speed regulation technology develops rapidly and its performance is superior to any other AC speed regulation (such as step-down speed regulation, Slip speed, hydraulic coupling, etc.), and the structure is simple, stable and reliable, a wide range of speed, energy-saving significant. In particular, the recent rapid development of high-voltage inverter, high-speed high-speed motor to become a reality. At present, most of the high-voltage inverters are used in the application areas of fans and pumps, but few are used on the belt conveyors.
