SEC series of passenger elevator with small (without) machine room adopts the current world's most advanced permanent magnet synchronous gearless traction technology, combining with the fully-computerized intelligent control system and electromagnetism-dedicated VVVF inverter, which enables this series of products have the excellent performance of green, environmental friendly, efficient, energy-saving, space saving, safe and comfortable etc.
This series of lift elevators can be widely used in hotels, commercial buildings, middle and high-end residential buildings to fully meet needs of daily vertical transport of passengers.
Intelligent microcomputer control system
Highly integrated 32-bit full-digital microcomputer control system is characterized by perfect function deployment, fast data processing, real-time response capacity and stronger anti-interference ability.
Serial communication technology
Only a few of wires are required to realize free and smart handling of floor call, car command and group control signals, thus dramatically reducing wiring between the control cabinet and other electrical devices of the passenger elevator. This technology can greatly improve the system’s reliability and reduce installation and maintenance intensity and difficulty.
High-precision vector inverter
Imported high-precision closed-loop vector inverter is applied; its hardware and software systems are specially designed for permanent magnet synchronous gearless host. Through motor current magnitude and phase angle adjustment, it supports real-time control of the host rotation torque, thus ensuring perfect operation quality of the lift elevators .
Imported high-precision sine and cosine encoder is adopted with 10 times of the precision of the traditional incremental encoder. It can promptly and accurately feed back the real-time running speed of the passenger elevator to the control system, thus ensuring the elevator to run according to the best speed curve.
