LEITNER sets standards in drive technology

Reliability and environmental protection

Eficiencia económica LeitDrive

The demands on ropeway installations today are ever-growing. Especially with regard to cost effectiveness, reliability and environmental protection, expectations are very high. LEITNER fulfills them with innovative high-tech solutions. The new LeitDrive frequency converter marks a new quality standard in drive technology and continues the successful development building upon the direct drive. It converts the mains voltage and allows regulation of the motor’s number of revolutions, be it a direct drive or a conventional drive. This ensures that the installation is provided with the amount of power that it needs. Thanks to LEITNER’s long-standing experience and technological know-how, this new system can be tailored precisely to the needs of customers using ropeways.

Efficient and cost-effective

Using cutting-edge technologies, the interaction between the converter and the motor can be perfected. The powerful controller software ensures that the motor runs economically and efficiently in all load ranges. Especially in combination with the LEITNER direct drive, the LeitDrive reaches a very high degree of overall efficiency. Thanks to the use of standardized power modules, spare parts can be acquired more quickly and at a lower cost. There are additional advantages in the area of maintenance: The converter cabinets are especially maintenance-friendly and all components are easily accessible. All components come from LEITNER. There is no longer a need to hire third-party experts. The entire support service is carried out quickly and reliably by LEITNER.

Modular and unusually compact design

A great advantage of the LeitDrive frequency converter is its modular and unusually compact design. Individual modules, each with a power of 250 kilowatts (kW), can be connected in parallel. The system’s power range goes from 250 kW into the high megawatt range. Thanks to its small width of just 400 millimeters per module, the system can be set up in a very compact and space-saving manner and tailored precisely to the needs of ropeway customers. A liquid cooling system ensures optimal temperature management of the IGBT power electronics.

Quiet and environmentally friendly

The new converter offers all the advantages of an AFE (Active Front End) frequency converter as well as improvement of the power quality at the feeding point and avoidance of reactive power. This enables ropeway operators to use their power supply much more efficiently. The liquid cooling system allows waste heat to be processed through heat exchangers in order to provide heating and hot water for the buildings. The liquid cooling of the drive components also reduces noise emissions considerably. This creates greater comfort and strengthens acceptance of the whole ropeway installation.
