State-of-the-art elevators offer maximum ride comfort: almost silent operation and acceleration as well as smooth, jerk-free deceleration. The encoder, which supplies the drive with feedback signals from the motors, plays a key role in this. The Orona group, a leading provider of mobility solutions headquartered in Spain, relies on encoder technology from SICK for its leading-edge elevators.
In Europe one out of 10 new elevators is Orona, and globally more than 250 000 elevators use Orona technology. Orona’s commitment to innovation and eco-efficiency is the key to its growth with the objective of consolidating itself among the top five elevator manufacturers in the world. Orona elevators excel with maximum comfort. This is partly attributable to the SICK encoders, which allow for jerk-free acceleration and deceleration.
However, this feature is not only indispensable for comfort, but also for a vast array of other aspects that make for top-notch elevators. It reduces the noise emission of elevators in office and residential buildings. Sudden load and force peaks acting on the mechanical system and the motor are limited. This, in turn, increases the service life of all components, and ensures maximum reliability and availability, low maintenance and maximum cost-effectiveness.
When Orona introduced gearless motors for their elevators, the company chose absolute encoders with the HiperFACE from SICK’s SRS/SRM50 line. As motor feedback systems, encoders provide the drive with the values required to control positioning, acceleration and deceleration. With their high resolution of 32 768 steps per revolution, the SRS/SRM50 encoders enable high-precision positioning of the elevator car and maximum reproducibility.
In addition, the encoders support the complex, non-linear S-ramps for acceleration and deceleration in an optimum way. Fast data transfer is ensured by the HiperFACE interface, which was developed by SICK and has evolved into an industry standard.
Today, Orona purchases about 10 000 SICK encoders annually. Safety technology offers new perspectives for an even closer cooperation between Orona and SICK Automation. As a leading provider of industrial safety technology, SICK offers sensors, systems, solutions and services that allow for the highly effective implementation of fully standards compliant safety infrastructures.
