电梯节能的技术策略与政策建议

Proposal about the Elevator Energy Saving Technological Strategy and its Policy

分别从电梯的机械和电气控制领域介绍了电梯节能的技术策略，包括高效率的有齿轮曳引机、永磁同步无齿轮曳引机、直流共母线变频调速、带回馈功能的变频调速、矩阵变频器的使用等。此外，还为我国制订电梯节能的政策提出了建议。

This paper introduces the elevator energy saving technological strategy from the elevator＇s mechanical parts and electric control units including the high efficiency gear traction machine, the permanent-magnet synchronous gearless traction machine, D. C. and common bus VVVF speed control, VVVF speed control with the energy feedback and the array frequency converter etc., and also puts forward the suggestion to make the elevator energy saving policy.
