Gearless Elevator

KONE is a global leader in providing complete and innovative solutions for the design, installation, modernisation and maintenance of elevators and escalators and the maintenance of automatic building doors. In 1996, the company assumed the technology leadership in the elevator industry by developing the KONE EcoDisc hoisting machine. The current 3rd generation of the system has gone through 10 years of quality improvements – constantly increasing the application range, reliability, and ride comfort. EcoDisc is the core technology of all its gearless elevators. It employs a permanent magnet synchronous motor, frequency control, and low friction gearless construction. Salient features: a reliable machine – low revolving gearless motor with extremely low levels of wear; incorporates an axial permanent magnet rotor that constitutes the single moving part; more efficient than traditional machines – needs less starting current, consumes less power and needs no oil; less starting current means a smaller back-up generator which saves costs; signi?cant cost savings are achieved by the use of lower duty risers and fuses, made possible by a peak starting current of just 30 to 40 per cent of equivalent traction units; low rotational motor speeds, combined with the V3F drive system offers unrivalled ride comfort; space-saving elevator design – no need for a machine-room; safe travel – fast response and optimum stopping accuracy are ensured by intelligent controls; easy maintenance – all controls that need to be accessed for maintenance are grouped in a special, compact maintenance access panel; and dependable LCE control system – a modular control system design using serial communication with self-diagnostic capability offers great reliability. For a typical 8 floor elevator the savings in machine room and shaft costs with MonoSpace solution varies from Rs. 100,000 to 250,000 depending on size of the elevator and whether it is a brick shaft or an RCC shaft.
