GPM-III Series
Utilizes Advanced Technologies to Succeed

Higher Speeds

As buildings grow taller, the need for faster elevators becomes more pressing. To meet the market's demands, Mitsubishi Electric announces the fastest passenger elevators in the world as verified by the Guinness Book of Records. Series GPM-III is available for elevators with rated speed of 120m/min. and higher.

Wide Range of Improved Design Menus

The design of the car interior and and signal fixtures has been completely revised for the Series GPM-III. The extensive design menu is sure to suit virtually any type of building. Choose form a variety of styles in many finishes and colors.

Futuristic Key Technologies

Series GPM-III Elevators use advances in core technology to realize optimum performance and operation efficiency. The advances include new gearless traction machines which utilize the PM (permanent magnet) motor, VVVF (variable voltage, variable frequency) inverters, AI (artificial intelligence), and Data Network Systems.

Intelligent Door System

And advanced RISC (Reduced Instruction Set Computer) microprocessor and VVVF inverters also control the elevator doors. This intelligent system detects the actual door load conditions at each floor and automatically adjusts the door speed and torque to suit. The result is stable, sensitive door opening and closing.

Variety of Features and Functions

A wide variety of both standard and optional features and functions is available with Series GPM-III, to improve passenger safety and comfort and to simplify building management.

Traction Machine with PM Motor
(Delivers the Optimal Performance)

Pioneered by Mitsubishi

Mitsubishi Electric presents a world first: a new type of gearless traction machine for high-speed elevators with a PM motor. This unique application of PM motor and double disk-brake system to the elevator traction machine enables several improvements - including higher efficiency, greater comfort, and maniaturization.

Improved Efficiency and Response

Because it does not require an exciting current, the PM motor delivers higher efficiency and quicker response compared to conventional motors. Furthermore, the PM motor maintains this level of efficiency regardless fo the number of poles.

A More Comfortable Ride

The PM motor makes it possible to suppress harmonic noise to a level below that of conventional induction motors. Furthermore, The PM motor features a quick response time since it requires no exciting current. Again, the reduced noise and vibration translates into a more comfortable ride for passengers.

Miniaturization

Traction machines with PM motors are smaller and more compact compared to those with conventional induction motors. The PM Motor allows for a multi-pole arrangement and the result is a more compact machine. At the same time, the unit's height is reduced by the application of a double disk-brake system.

VVVF Inverter Drive
(Share a Ride in Comfort)

Unique to Mitsubishi

Mitsubishi Electric was the first in the world to develop successfully VVVF inverter control technology for high speed elevators. We also introduced inverters throughout the entire line-up--from low- to super high-speed ranges. Recent advances have led to even further improvements in operation.

Precise, Effective Speed Control

Mitsubishi VVVF inverters make the ride much smoother by precisely adjusting speed control with voltage and frequency regulation. The inverters also include the latest low-nouse modules to make the ride even quieter.

Practical Application

Mitsubishi Electric has already installed the world's fastest VVVF inverter-controlled passenger elevators to the Landmark Tower in Yokohoma, Japan. These elevators provide a quiet, comfortable ride as well as large savings in energy.

Even More Advances

Series GPM-III elevators use further advances to control the motor speed. Utilizing the lates in semiconductor technology, Mitsubishi has incorporated on a single System LSI device, several control systems and our all new high speed digital signal processor.

AI Supervisory Control
(incorporates Advanced Artificail Intelligence)

Mitsubishi Technology

Using its original Expert System and fuzzy-logic technology, Mitsubishi Electric has developed a supervisory sustem that improves operation efficiency and increases user satisfaction.

Analytical Decision Process

Series GPM-III elevators use especially designed AI supervisory systems: the Al-21 for two-to-four car and the AI-2100N for three-to-eight car elevator systems. Logical, qualitative judgements are made using traffic databases stored in the system.

Greater Passenger Satisfaction

The AI system evaluates the psychological waiting time for users and factors it into the decision process when responding to hall call. This Mitsubishi-pioneered technology provides optimum service and user satisfaction by eliminating the irritation felt while waiting for a car on any floor of the building.

Improved Carrying Efficiency

The AI-2100N system utilizes nueral networks and car allocation tuning to improve carrying efficiency during peak periods, i.e., morning, lunchtime, and evening rush hours.

Data Network System
(Distributed Microprocessors Enhance the Human-Elevator Interface)

A Proficient Network

The Data Network System uses microprocessors distributed throughout the elevator configuration for more flexible control of the overall system. Each microprocessor is specially designed for thought-processing, thus greatly enhancing the "Human-Elevator Interface."

Highly Reliable and Efficient System

Each microprocessor is connected via a serial transmission line to ensure higher reliability and efficiency. The system also shares diagnostic programs among the microprocessors and incorporates backup systems to further enhance reliability and passenger safety.

Increaed Flexibility

The distribution of data network microprocessors simplifies modification to features or operation of the sytem, allowing the system to evolve with the changing needs of the building and its tenants.

Elevator Design
(Complement the Building Environment)

The original elevator designs of Mitsubishi Electric can be found in buildings around the globe. Backed by a corporate design lab, the relaxed working atmosphere of the design engineers enables them to create avant-garde designs worthly of architectural praise.

Selection of Finishes

A wide variety of finishes, colors and materials are available for door frames, hoistway door panel, and the walls, flooring and door panels inside the elevator car. They can be combined in many variations to suit the building environment. The indicator type is also selectable.

A Rich Assortment of Designs

The range of designs for Series GPM-III elevators is wide and varied, and includes soft natural tones for virtually any type of building. Choose from the 13 car-ceiling designs here, or from the selection of GPS-III designs, or alternatively select the "bare-cage" type. Elevator entrances come in a choice of five designs, making it possible to match the door frame to the elevator hallway.
