Drives for residential elevators and escalators

Elevate comfort and reliability to new heights

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 elevators and escalators. Even thrill-seekers looking to reach new heights in ski resorts have an impact on the industry.

You can rely on smooth, silent and safe performance, combined with cost synergies, by incorporating Danfoss AC drives designed specifically for the elevators and escalators industry into your construction. 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 you can enjoy the ease of dealing with a single supplier, because aside from AC drives, Danfoss is already present in building automation solutions in almost every building, supermarket or factory globally.

Traction elevators and escalators

These are the most common types of elevator and escalator 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. Elevator-specific functionalities make it easy to integrate the AC drive into a new elevator 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.

Hydraulic elevators

Hydraulic elevators, also widely used, have pistons that move the car along guide rails. When AC drives are used, the hydraulic pump is driven in relation to the true demand with the lowest losses. The hydraulic oil doesn’t get hot and the lift will have unlimited cycles per day, shorter cycle times and very high efficiency. Energy savings exceed 50%, and total savings of up to 75% are possible when oil coolers are removed and the air conditioning has less work to do. Modernization of an existing lift to use AC drives can be done in a matter of hours.
