Elevator machines

Elevator technology from ZIEHL-ABEGG globe. Whether in residential buildings, offices, hotels, or the highest buildings in the world: ZIEHL-ABEGG represents high reliability, safety, and ride comfort. Users worldwide rely on elevator drives from ZIEHL-ABEGG.
ZAtopx, with an advanced StPUGurt (steel and PU belt) concept combines engine power with low noise levels. ZAdisc and ZAsyn, with their flat design, are utilized for elevators with and without a machine room. The gearless ZAtop model series ioffers flexible application and high efficiency combined with a narrow overall width for tight shaft dimensions.
With coordinated control technology from ZIEHL-ABEGG, we supply the complete system from a single source – whether for new construction or the modernisation of existing systems as a retrofit.

Advantages of ZIEHL-ABEGG elevator machines

Modern elevator technology from ZIEHL-ABEGG offers advantages for elevator manufacturers, as the elevator motors can be designed for specific requirements. In combination with coordinated control technology, elevators achieve high efficiency with high-performance motors – regardless of whether they are new systems or upgraded versions of existing systems. In continuous operation, this can contribute to reducing energy consumption and thereby lowering operating costs.

RETROFITBLUE – The Concept for the Modernization of Elevators

For retrofitting and modernizing elevators equipped with outdated disc-rotor drives, ZIEHL-ABEGG provides the RETROFITBLUE modernization concept. Instead of original spare parts, freely available drive and control technology is utilized, fulfilling all current safety standards (e.g. UCM).

1. Replacement of electronic components and installation of the modern frequency inverter ZAdyn4CS

Switch from uneconomical original spare parts to brand-independent components from ZIEHL-ABEGG. The advanced technology from ZIEHL-ABEGG, freely available on the market, is likewise suitable for replacing first-generation disc-rotor drives.
The developed control technology facilitates reliable, cross-manufacturer communication between the existing disc-rotor drive, the frequency inverter ZAdyn4CS, and the new elevator controller.

2. Replacement of the outdated drive and installation of the new ZAdisc

With the completion of stage 1, the prerequisites for the rapid replacement of the old drive and the installation of the new ZAdisc have been established. The exceptionally flat design simplifies the substitution of the outdated disc-rotor drive with the new ZAdisc—even in constrained shaft dimensions. The installation of ZAdisc and the coordinated control technology can contribute to reducing maintenance costs and support the long-term utilization of the elevator system.

ZAtop

The permanent-magnet-excited gearless internal rotor elevator machine ZAtop was developed for traction sheave rope elevators with and without a machine room. The drives of the ZAtop series are available in various frame sizes: as a drive for a residential elevator as well as a drive for elevators with high speeds, large load capacities, and high travel heights. The internal rotor drives provide high energy efficiency, low-noise operational performance, and comply with all specifications of the Elevator Directive 2014/33/EU.

ZAtopx

The ZAtopx elevator machine is a gearless motor for elevators with or without a machine room, utilizing a flat belt as the suspension means. As a result, the dimensions of traction shafts and deflection pulleys have been reduced to 100 mm, rendering these drives more compact. ZAtopx thus provides a suitable basis for implementing compact, smooth-running elevators.

ZAdisc

ZAdisc is a permanent-magnet-excited gearless disc-rotor drive for traction sheave rope elevators without a machine room. The elevator machine ZAdisc, which complies with all requirements of the Elevator Directive 2014/33/EU, can enhance the performance and ride comfort of the elevator installation. Due to its flat design and the attachment of the drive to the guide rails, ZAdisc enables the realization of space-saving shaft dimensions.

ZAsyn

ZAsyn is a permanent-magnet-excited gearless external rotor drive specifically developed for traction sheave rope elevators with and without a machine room. The motors of the ZAsyn series provide high energy efficiency and low-noise operational performance, complying with the provisions of the Elevator Directive 2014/33/EU. Due to their flat design and mounting on a wall in the elevator shaft, shaft dimensions can be optimized.

Control technology from ZIEHL-ABEGG—For new construction and modernization of elevator systems

Only when the control technology is coordinated with the elevator drive can high performance be extracted from the drive system. Accordingly, the frequency inverter ZAdyn delivers comprehensive functionality within a compact footprint and facilitates precise speed control and regulation—providing high ride comfort with low noise emissions.

The power feedback unit ZArec enables the exploitation of energy-saving potential and can thus contribute to improving energy efficiency.

The evacuation units EVAC 3 ensure the safe evacuation of the elevator in an emergency.
