Elevators Tailored to a Customer's Needs
Miniaturized Equipment Suits Any Building
Mitsubishi Electric’s advanced technology is driving a new age in elevator miniaturization. The newest models are not only more sophisticated than ever, they offer greater space savings. The traction machine, control panel and other key equipment can be adapted to suit required speed and capacity for any building use or design.

• Compact Control Panel
• Miniaturized Equipment
Compact Traction Machine
Mitsubishi Electric was first to replace induction motors with highly efficient permanent magnet (PM) motors for high-speed and super high-speed elevators, fully developed in-house. Since PM technology is uniquely suited to miniaturization, permitting the development of a more compact gearless traction machine for high-speed elevators that boast a 2.0 to 4.0 meters per second (6.6 - 13.1 ft./sec.) speed at a capacity up to 1600 kilograms (3,527 lbs.). Slim and efficient, the PM motor is a demonstration of Mitsubishi Electric proprietary stator core technology that results in a compact traction machine that's about 30% smaller in axial dimension than previous models.
Compact Control Panel
The control panel that drives the PM motor incorporates the most advanced, low-loss IGBT (Insulated Gate Bipolar Transistor) as well as optimal design. The result is a control panel less than half the size of previous models.
Designed for Comfort, Safety and a Smooth Ride
High-speed computer processing is behind precise adjustment of elevator machine controls to eliminate noise and vibration during operation. To ensure safety during boarding, door sensors detect passengers and objects in the area near the doors.
• High-Speed Computer Processor
• Advanced Door Controls
Advanced Drive Technology• High Accuracy Landing Feature (maximum±5mm)
An exclusive elevator control system that integrates digital control circuitry into a high-accumulation LSI results in added performance and reliability. High-speed processing enhances motor control precision to deliver a more comfortable ride. The low-noise PWM (pulse width modulation) inverter unit incorporates the latest power IC module, while the cooling unit uses the highly efficient heat-pipe method to deliver even greater reliability and space savings.
Sophisticated Door Systems
Mitsubishi Electric elevators use a VVVF Inverter Drive control system to ensure doors open and close smoothly and quietly. A high-efficiency, one-chip RISC microcomputer enhances the doors’ sensitivity by calculating the weight of the door panels at each floor, the strength of the wind, and even waste in the sill groove. Auto Tuning provides just the right door opening and closing speed at each floor for safety and reliability. In addition, the learning-capable Door Load Detector offers high-precision door sensitivity, monitoring changes at each floor to allow prompt door-motion return when abnormal pressure is applied.
Hall Motion Sensor
A conical infrared-light beam scans a 3D area near the open doors. Doors reverse and open if beams
are blocked during door closing.
Multi-Beam Door Sensor
Multiple infrared-light beams cover not only the full width of the doors but also a door height of
approximately 1800mm. Doors reverse and open if beams are blocked during door closing.
Active Roller Guide
(Please consult us when Active Roller Guide is required.)
Mitsubishi Electric’s Active Roller Guide greatly reduces lateral vibration of high-speed elevator cars.
An accelerometer detects car vibration during operation and actuators cancel the vibration with
optimally controlled electromagnetic force. The result is much better ride comfort than with a
conventional roller guide.
Passenger-Friendly Universal Designs
Mitsubishi Electric places enormous emphasis on elevator designs that provide all passengers with a safer, more comfortable ride. Elevator users come in all sizes and levels of physical ability, demanding the application of passenger-friendly features including large, ergonomically designed buttons and indicators, plus conveniences like voice guidance and thicker handrails.
• Larger Indicators and Door Open Button
• Tactile Buttons
• Voice Guidance System
• Thicker Handrails
New indicators are made more viewable, approximately 1.6 times larger than previous ones.
Redesigned for enhanced operability for every passenger, including those with visual impairments. New numerical design
and attractive color contrast help passengers easily recognize which button to press. Embossed button numerals help visually
impaired passengers easily locate the correct button with a simple touch.
Larger Door Open Button
An easy-to-use Door Open Button approximately 1.6 times larger than previous types, ensuring that passengers will not press the Door Close Button by mistake.
Voice Guidance System
Narrates information such as elevator traveling direction, floors to serve, and other messages.
Sonic Car Buttons
Emit electronic beep sounds when pressed to indicate the call has been registered.
Doors equipped with tempered glass windows allow passengers to be seen from outside the car, thus enhancing security.
A stainless steel mirror is available for car interior panels. When installed in the center of the rear wall, wheelchair users exiting from the car can visually check for obstacles behind them.
Handrails have been made thicker (38mm/1.5 in. in diameter) so that passengers can grip them securely as the car travels.
More Efficient Design Delivers Energy Savings
Mitsubishi Electric’s advanced control and operation technology provides significant power savings. Other environmentally responsible manufacturing methods include reduction of the amount of lead in wire soldering, and reduction or elimination of the use of potentially harmful substances such as vinyl chloride plastics during the manufacturing process.
• VVVF Inverter Control
• Energy Saving in Off-peak Periods
• Reduced Soldering Work
• Reduced Vinyl Chloride Plastics
VVVF Inverter Control
Mitsubishi Electric is the world’s first company to develop VVVF (variable voltage variable frequency) Inverter Control for elevators. By changing voltage and frequency simultaneously, VVVF Inverter Control allows smooth, high-precision control of the traction machine. A high-efficiency PWM (pulse width modulation) converter further regenerates electric power created from braking energy. The combination of VVVF inverter and PWM converter results in impressive power savings.
Energy Saving in Off-peak Periods
Mitsubishi Electric’s precise controller greatly improves energy efficiency by reducing energy consumption when elevators are in standby mode. In addition, during off-peak periods, the group control system goes into “sleep mode” and monitors elevator calls to further reduce energy requirements.
IT Drives Elevator Evolution
Our new technology creates benefits not only for passengers but also for building tenants and owners. The cutting-edge IT solutions Include the following:
• AI Group Control Systems* (optional)
• Elevator Information Display
• Touch panel system
• MelEye Elevator & Escalator Remote Mentoring and Control System
* Refer to pages 29 to 30 of the NexWay brochure for details.
Elevator Information Display*
The rich expressionistic technologies of Flash** software enable the LCD (10.4- or 15-inch) to reproduce stereoscopic direction arrows and animated pictures, as well as to play visual data from DVD or real-time CCTV sources.
* Please consult our local agents for the production terms, etc.

Touch Panel System
The Touch Panel employs advanced touch sensors and offers high reliability and durability. It displays both graphical destination buttons and customized messages. A light touch on the destination button is all that's needed to register a desired floor.
• The Touch Panel can be installed in a hall when the Destination Oriented Prediction System is applied
• Note that the Touch Panel cannot be used for elevators designed for visually impaired passengers, or for fireman service elevators.
• Also note that the Touch Panel cannot be used in the United States or in countries where regulations, such as EN 81-70, mandate specific measures for physically challenged passengers.
