The remarkable KONE EcoDisc elevator hoisting machine invention was introduced in 1996 and was immediately acknowledged as an outstanding conceptual and technical innovation. Its first application was to power the revolutionary KONE MonoSpace elevators. The range has greatly expanded so that most KONE elevators installed today feature EcoDisc technology.
EcoDisc powered elevators offer a unique set of benefits for all types of buildings:
Material and energy efficiency
Superior material and energy efficiency of EcoDisc powered elevators make them an ideal choice for environmentally sustainable buildings.
Besides meager power consumption, EcoDisc machines use no oil, removing the risk of contamination and fire that constantly threaten hydraulic systems.
A quantum leap in elevator technology
EcoDisc machines are based on a permanent magnet synchronous motor in combination with frequency control and low friction gearless construction.
EcoDisc technology is well proven by tens of thousands of units in operation and is well on its way to replace all other solutions of motive power used in elevators.
The energy miracle
The EcoDisc is highly economical, using only half of the power needed by comparable conventional systems.
Annual savings depend on the system and building, but vary from a few thousand kilowatt-hours for a single elevator to tens of thousands of kilowatt hours for a high-speed elevator group.
The peak starting current is just 30-40% of that of equivalent hydraulic and traction units, resulting in savings on fusing and power supply.
The EcoDisc machine is half the weight of a conventional power unit.
Its compact size minimizes elevator space requirements in all applications and, within a certain load/speed range, facilitates the KONE MonoSpace layout.
Strong and reliable
An EcoDisc machine has only one moving part, a very low-revving motor and gearless construction, guaranteeing reliable operation for decades to come.
Larger types for higher speeds and heavier loads use a `double rotor? structure.
Smooth and safe ride
Elevators powered by the gearless EcoDisc are exceptionally smooth and quiet.
Excellent controllability and accurate stopping means passenger safety, comfort and ease of use.
