Comfortable, Smooth and Pleasant Ride ExperienceLEHY-M-II/LEHY-H elevators are high-end elevators specially designed for applications including commercial buildings, shopping malls, hotels and luxury residential buildings. With Mitsubishi’s advantages in technology, such as variable-voltage variable frequency (VVVF) drive technology, double-PWM energy feedback technology and data network control technology, LEHY-M-II/LEHY-H elevators have undoubtedly become classic among the elevators of the world today.
LEHY-M-II/LEHY-H medium & high speed passenger elevator applies an efficient drive system and all-digital controls, increasing its speed to 8.0 m/s. The new generation of high-performance PM synchronous gearless traction machine uses large brake discs and low-noise disc brake to guarantee safe and sufficient braking torque, which greatly reduces brake noise, increases safety and reliability and extends the service life. It also has sensitive weighing sensors to accurately detect the elevator load in real time and make up the load at start-up based on the pre-torque, thus eliminating the discomfort caused at start-up, operation and stopping, and providing a comfortable ride to passengers when the elevators is running at high speed.
LEHY-M-II elevator uses a heat pipe radiation system, which increases the radiation efficiency and reduces the space required for radiation.
Compared with traditional open-loop voltage control, a more accurate closed-loop current control mode is now used to control the action speed and braking torque at all stages of the brake. This has remarkably reduced the noise when the brake works and improved the ride comfort.
LEHY elevator is the first to use the industry’s most advanced super high-power module system. Multiple fast protection circuits can better protect the power module, thus further improving the reliability of the drive system. Meanwhile, advanced topology design increases the system’s resistance to interference.
LEHY elevator uses various high-performance chips including 32-bit CPU, 32-bit high-speed data signal controller (DSC), and large-scale field programmable gate array (FPGA), and the world’s advanced Surface Mount Technology (SMT) technology, which realizes all-digital control and motor drive to further improve the control performance and reliability of the system and guarantee the comfort and safety of the elevator.

Application of Digital TechnologyIn recent years, Shanghai Mitsubishi has put in more efforts to apply and research digital technology in product R&D area. Regarding the structure, vibration, noise, transmission & control and other key technologies for high-speed elevators, Shanghai Mitsubishi has carried out systematic and component-level control simulation, multiphysics simulation and single- or multiple-field coupling simulation of stress field, flow field, heat field, sound field and electromagnetic field, and has applied a digital product research platform and a modern test platform to improve the capability and level of elevator development.
Energy Feedback Technology (Standard)Double-PWM controlled energy feedback technology can feed the regenerative energy consumed by power resistors back to the grid without pollution, which saves energy by more than 30% than common VVVF elevators and complies with national standards for energy consumption.
LIMAC Elevator Hoistway Safety SystemLIMAX elevator hoistway safety system is introduced from ELGO in Germany, which is compatible with reduced stroke buffers, thus enabling the elevator to reach SIL3, the highest safety integrity level in the elevator industry and solving the speed control problem in the hoistway (especially the top and bottom terminals).
Intelligent voice callTouch-free, hands-free buttons. Recognition of personalized floor information, e.g. dining hall. High accuracy of recognition and strong anti-noise capacity (50 dB of noise, recognition rate ≥90%)
Data Network Control TechnologyData network control technology based on CANBUS (filed bus) features high communication rate and large data volume, and use independent microprocessors respectively in the elevator car call controller, floor indicator in the car, door operator controller, buttons and floor indicators of each landing, and other various subsystems. Communications between various subsystems only need a few signal lines. This has greatly improved the reliability, resistance to electromagnetic interference and flexibility of the system and reduced the maintenance costs.

AC VVVF Speed Regulation Technology and All-Digital Control TechnologyShanghai Mitsubishi adheres to the philosophy of well-grounded development and constantly uses the latest technologies and components in VVVF drive of elevators enable VVVF speed regulation technology to develop rapidly towards high performance, high reliability, digitization and miniaturization. Shanghai Mitsubishi also adopts space vector pulse width modulation (SVPWM) technology to realize elevator speed regulation, takes the lead in adopting world’s latest sixth generation of high-power module, 32-bit high speed digital signal controller (DSC) and large scale integrated circuit and other advanced electrical components, enabling the elevator to accurately regulate the motor rotation completely according to optimum speed variation curve and operate following the perfect speed curved optimized according to modern ergonomics principle. All these have realized all-digital control and motor drive in true sense and enabled the elevator to run smoothly, safely and efficiently.
Destionation Oriented Allocation System (DOAS) can greatly improve the utilization of the elevator and shorten average passenger wait time. When a passenger has pressed the button of the destination floor at the hall, DOAS will inform the passenger of the car allocated and the passenger can go and wait there. When the elevator has arrived, the passenger does not need to press the button in the car, because the elevator has registered the call automatically and will carry the passenger to the destination floor.
ITS-21 or ITS-2100 group control system uses a high-performance multi-core CPU processor for computing to process complex algorithms fast. A high-speed data network effectively increases the throughput and scalability of the system. The application of expert system, fuzzy logic technology and neural network technology can allocate the car intelligently, thus greatly shortening passenger wait time and ride time and reducing the energy consumption of the elevators operated inside the building.
A universal decoration system is applied to all LEHY elevators, including LEHY-III, LEHY-MRL, LEHY-M-II and LEHY-H. On the basis of preliminary survey and demand analysis, the newly developed decoration system has much better flexibility and responsiveness and provides customers with different grades and styles of decoration.
To install the hall call without bottom-box, a rectangle cut-out is not required on the wall, but a small round hole, making the installation easier and more convenient.
The buttons glimmer in standby mode by design, making the numbers on the buttons easily recognizable even in the dark.
The new integrated car is applicable to most buildings and has various styles available to meet customer needs.
No additional decoration layer, less space, less cost;One-time delivery, less labor, less time;OEM product, safe and secure.Car ceilings of LEHY-M-II/LEHY-H elevators use LED lighting with a service life five times longer than conventional fluorescent lamps, saving energy by at least 50% and substantial maintenance costs and using costs.
Buttons can be pressed up to 5,000,000 times and have reinforced stainless steel button caps specially designed for residential elevators. They also have anti-drop snap hook design.
(A block of 1 kg drops down to the button surface from a height of 0.5 m three times and the button can still work normally. This is higher than the requirements for Category 1 elevators in EN81-71.)
