随着新技术的不断发展,永磁同步电动机的生产技术已经成熟,并快速的进入到电梯驱动系统,成为电梯行业继VVVF技术之后,又一次重大的技术进步。永磁同步曳引电梯具有节能环保、低噪音、体积小等特点,近年来已愈来愈多被用户广泛采用。现实生活中由于停电、故障、火灾、事故等因素导致电梯出现的紧急情况时有发生,但永磁同步曳引电梯困人的紧急救援因其结构特点而带来的特殊性就成为一个不可忽视的问题。1永磁同步曳引电梯特殊情况的应急救援对于无盘车手轮的永磁同步曳引电梯,当电梯发生故障或因供电系统停电而困人时,轿厢和对重
With the continuous development of new technology, the production technology of permanent magnet synchronous motor has matured and entered into the elevator drive system quickly, becoming another major technological advancement in the elevator industry following the VVVF technology. Permanent magnet synchronous traction elevator with energy saving, low noise, small size and other characteristics, in recent years, more and more users have been widely used. In the real life, the emergencies occurred in elevators due to power outages, faults, fires, accidents and other factors, but the special nature of the emergency rescue of people with permanent magnet synchronous traction elevators due to their structural features has become an important issue The problem. 1 Permanent Magnet Synchronous Traction Elevator Emergency Rescue In the case of a permanent magnet synchronous traction elevator without a disk drive wheel, when the elevator fails or the power system is in power failure, the car and the counterweight
