With urbanization driving the need for taller buildings, and an aging population looking for more well-being in their lives, easy and fast access with high comfort levels and energy efficiency are key parameters in the design of today’s lifts and escalators. Even thrill-seekers looking to reach new heights in ski resorts have an impact on the industry.
Danfoss Drives is a leading supplier of AC drives for the lifts and escalators industry. Our products provide effortless speed control and optimized efficiency of equipment in, for example, commercial and residential buildings, ski resorts and industrial sites all around the world. And, aside from AC drives, Danfoss is already present in building automation solutions in almost every building, supermarket or factory globally.
Danfoss Drives’ broad range of AC drives, including both VLT® and VACON® brands, provides flexibility in the development of new equipment and modernization of existing installations. When a new lift series or escalators are designed, Danfoss Drives is able to draw on years of experience related to applications and AC-drives technology to support the development.
Cooperation in analyzing the operation of drives using test towers, and optimization of the controls, performance and system as a whole, are important areas of our expertise. And our wide service offering covers scheduled maintenance requirements and optimization of modernization packages.
These are the most common types of equipment. Cars are maneuvered by means of rolling ropes over a pulley system, and the load is balanced by a counterweight. Accurate control of a high-efficiency motor using an AC drive provides the required ride comfort. Lift-specific functionalities make it easy to integrate the AC drive into a new lift series or to modernize existing installations.
In escalators, AC drives enable low-speed idling and full-speed operation with soft acceleration and deceleration. The high efficiency and smooth operation of the equipment guarantees its long lifetime. Both new equipment and existing installations benefit from a lower total cost of ownership.
