KONE EcoDisc

A typical EcoDisc motor installed in the shaft (Hong Kong version usually have a safety protection guard to prevent the workers get injured). The right hand side of the picture is a Variable Voltage Variable Frequency (VVVF) drive and the other part of the LCE controller.

The Kone EcoDisc is a gearless hoisting machine made by Kone since the introduction of their MonoSpace elevators in 1996, the world's first machine room less elevator system.

Overview

The EcoDisc motor was first introduced in 1996. It is a Rotational Linear Motor combined with synchronous axial technology and NeFeB permanent magnets. The EcoDisc motor has many benefits; such as superior material and energy efficiency, using no oil at all, has a permanent magnet synchronous motor in combination with frequency control and low friction gearless construction, all of which combine to be able to use only half the power needed by comparable conventional systems. Not only that, it is half the weight of a conventional power unit, and is very simple, with only one moving part, making it very smooth and quiet to operate.

In 2013, Kone started to provide another type of hoisting machine also called EcoDisc but it was totally redesigned which make the motor smaller than original-sized motor[1] and that will force Kone to distinguish between original-sized motor or smaller-sized motor. To make MonoSpace and MiniSpace (mid-rise model only) both have two different types of motors to make the model name both start with S[2] and N[3].

Application

The EcoDisc motor was first used to power the MonoSpace elevators, but soon expanded to most of the Kone elevator product line, such as the MiniSpace[4], EcoSpace, EcoSystem MR, Alta, JumpLift and TranSys elevators. All of those are working with their LCE Controller.

Sizes of EcoDisc motor

MX 05

This is the smallest EcoDisc machine.

MX 06

A bigger EcoDisc machine compared to MX 05.

MX 10

This is the most common EcoDisc machine and it is used in the MonoSpace elevators.

MX 18

The EcoDisc MX 18 is mainly used in MiniSpace and possibly EcoSystem MR as well as some modernized elevators done by Kone.

MX 20

A large and more powerful EcoDisc machine compared to MX 10. It is mostly used in the MiniSpace MR (2:1 roping) or TranSys MRL (4:1 roping) elevators.

MX 32

This is a large machine with two motors fixed on the floor. It is used on the Kone Alta elevators.

MX 40

Similar but larger than MX 32. It is used on the Kone Alta elevators.

MX 100

This is the largest EcoDisc machine. It is used on the Kone Alta ultra high speed elevators. By 2013, the Kone UltraRope can be used on this machine.

Trivia

  • The main part of the Kone LCE has divided with three generations:
    • First Generation (1996-2005): Controller and variable-frequency drive separated (V3F16). Equipped with the heat resistors (doesn't provide Regenerative Drive functions).
    • Second Generation (2005-2012): Controller and variable-frequency drive combined (V3F18 or V3F25). Regenerative Drive functions provided.
    • Third Generation (2012-present): Controller and variable-frequency drive separated again (Vacon KR6 or Vacon KR7). Regenerative Drive functions provided.
