Cutting-edge Technologies

Intelligent, ultra-thin, silent PM door motor system

The whole series employ ultra-thin PM-driven door motor technology, door motor control system is controlled by a 32-bit high-speed digital signal processor, with speed-current double closed-loop feedback control.

New generation PM traction machine

LEGY-III small machine room elevator is equipped with permanent magnet (PM) synchronous gearless traction machine that introduces advanced technologies such as Japanese Mitsubishi Electric’s articulated motor stator core

DigTel-III elevator data Transmission system

It integrates digital multi-party call for intelligent use of elevator, bears elevator IoT function, and provides AI pre-diagnosis service based on big data of elevator, with strong scalability, carrying future development direction.

CONFIGURATION UPGRADE

Configuration upgrade

LEGY-III (F) can meet the standard of fireman elevator

Conform to the standard of fire elevator GB/T 26465-2011

IP level has been comprehensively improved

All pit parts use high IP grade switches

Optional roller guide shoe

The roller guide shoe can be configured to meet the needs of users

Upgrade optimization

Upgrading and optimization of man-machine components

Full height control box, elegant and atmospheric

The panel width is 220mm, the front wall/car wall is flush, with strong overall feeling and more atmospheric appearance

Segment code display+bit segment LCD

The appearance is upgraded. LEGY-III has designed a new segment code display, a new segment LCD interface, which is exquisite and gorgeous. The graphical display is more intuitive and humanized, effectively improving the product's sense of quality and value.

 

Independent display of running direction, continuous font

Bits display characteristic fonts, and the background is exquisite and gorgeous

The arrow font design with the characteristics of Shanghai Mitsubishi is simple and beautiful

The display window has a larger size and a more impressive appearance

 

PIM Technology

PIM Technology

PIM (Power Integration Module)

It integrates traditional rectifier bridge module and temperature detection function

Select the latest 7th generation PM module

Compared with the sixth generation module, the working junction temperature is increased from 150 ℃ to 175 deg; C. With stronger output capacity, the module has built-in temperature detection and more accurate over temperature protection

Module selection shall be carried out in strict accordance with the design basis of SMEC

Full load power cycle life:10million times;
Design life:20years;
Design basis of other frequency converter manufacturers:1.5~2.5 million times

All 19 functions are tested on the one touch debugging console

Refuse to take the defective product offline

Self test

24-hour intelligent self check

Every time the elevator is powered on or every 24 hours, if the elevator is idle, carry out an intelligent self-test of balance coefficient and braking torque

If the balance coefficient exceeds the range but is within the threshold value, a prompt will be given; if it exceeds the threshold value, a warning will be given to stop the elevator; If the braking torque is less than the threshold value, the elevator will be stopped for warning

Save space

More space saving in the computer room

Miniaturized control cabinet

The frequency converter based on PM module, the main circuit components realize on-board, and the control cabinet is miniaturized through highly integrated design

Real small machine room design

The size of the machine room is the same as that of the shaft, which greatly reduces the building area, improves the utilization rate of the building, and saves the construction cost.

 

CONTROL SYSTEM

New control system architecture

New development direction of intelligent elevator in the future

Traditional lane: first bus (control signal)
High speed lane: intelligent second bus (intelligent data)
AAN voice station announcement device
Remote monitoring of elevator Internet of Things
Digital multi-party call
 

Technical features

Technical features

Articulated stator core technology

Patented technology of SMEC Electric

 

Digital power system

The power supply system using full switching power supply instead of traditional transformer power supply not only significantly reduces the system energy consumption, but also has the characteristics of small size, high security, high reliability and strong anti-interference ability

 
 

Shanghai Mitsubishi LEGY-III full digital power supply system
Lower energy consumption: efficiency is 20% higher than transformer
Small output voltage fluctuation: not affected by grid voltage fluctuation
Self protection function: over-current, over-voltage protection, etc

Safety and quality assurance

Design basis of high safety level

The new generation of standard ladder type LEGY-III and other ladder types of SMEC implement the same design basis
Brake:15million times;Car door lock:15million times
Door lock of landing door:3million times
Terminal switch:15million times……

Self production rate is at the top of the industry: adhere to self production and ensure quality

Components related to the safety of users: safety gear, speed limiter, buffer and other core components related to the reliability and performance of the elevator: control panel, frequency converter, traction machine, etc.
Components involving aesthetic and visual appearance: operation box, landing call, etc

Understand the design basis of SMEC
