曳引机是电梯的核心驱动部件,是电梯的动力之源,其性能直接影响电梯的安全可靠程度和乘坐舒适性。随着电梯技术发展的日新月异,曳引机技术的革新也在与时俱进,从最初的直流驱动式、交流双速驱动式、交流调压调速式到今天的永磁同步式,引领着电梯向更加安全、更加舒适、更加节能的方向迈进。无论是最初的直流曳引机还是交流双速曳引机等,与今天广泛使用的永磁同步曳引机,简单说就是有齿曳引机与无齿曳引机两大类。面对这两大类电梯,根据GB7588中的要求,这两大类电梯轿厢上行保护装置,能否可靠安全制停。
The traction machine is the core driving component of the elevator and the power source of the elevator. Its performance directly affects the safety and reliability of the elevator and the riding comfort. With the rapid development of elevator technology, the innovation of traction machine technology is also advancing with the times, from the initial DC drive, AC double speed drive, AC speed regulator to today’s permanent magnet synchronous, leading Elevator to safer, more comfortable, more energy-efficient direction. Whether it is the first DC traction machine or AC two-speed traction machine, and today’s widely used permanent magnet synchronous traction machine, simply toothed traction machine and toothless traction machine two broad categories. In the face of these two categories of elevators, according to the requirements of GB7588, these two categories of elevator car uplink protection device, whether reliable and safe stop.
