How Do Modern Elevators Achieve Energy Saving and Noise Reduction?
As modern buildings continue to rise in height, elevators have become an essential part of daily vertical transportation. However, traditional elevators often suffer from high energy consumption and significant operating noise. Today’s elevators not only focus on ride comfort but also emphasize energy efficiency and quiet performance. So how do modern elevators achieve energy-saving and noise reduction? Let’s take a closer look at the core technologies.
1. Permanent Magnet Synchronous Traction Machines Improve Efficiency and Reduce Noise
Traditional elevators use geared traction machines, which consume more energy and generate mechanical noise. Today, more elevators are equipped with gearless permanent magnet synchronous traction machines (PMSM):
Gearless design reduces mechanical friction and delivers quieter operation
Higher motor efficiency saves over 30% energy
Compact structure, ideal for machine room-less (MRL) elevators
2. VVVF Inverter Drive System for Energy-Efficient Operation
Modern elevators widely use VVVF (Variable Voltage Variable Frequency) inverter control systems to precisely control motor speed and improve performance:
Reduces current shock and extends motor service life
Smooth acceleration and deceleration minimize vibration and noise
Automatically adjusts power consumption based on load
A-FLY provides multiple compatible elevator inverter parts and elevator control system components for easy maintenance and replacement.
3. Regenerative Power System for Energy Reuse
When an elevator travels upward with a light load or downward with a heavy load, it passively generates electrical energy that is often wasted. By installing a regenerative power unit, this energy can be returned to the power grid for reuse:
Saves 30%–45% of energy consumption
Works efficiently with inverter systems for eco-friendly operation
Reduces machine room heat and noise
4. Silent Design in Car and Guide Systems
To reduce operating noise, elevator mechanical components are optimized with silent engineering designs:
Silent guide shoes – reduce friction with guide rails
Buffer systems – improve vibration absorption at landings
Quiet door operators – use permanent magnet DC motors to lower noise
These components are essential in elevator modernization projects. A-FLY supplies compatible car guide shoes, door system parts, and buffers for major elevator brands.
5. Intelligent Standby Energy-Saving Mode
Energy saving isn’t limited to operation—modern elevators feature sleep mode technology:
Automatically turns off cabin lighting and fan when idle
Inverter enters low-energy standby mode
Uses sensor-based wake-up for fast response
Conclusion: Energy Saving and Quiet Comfort Are the Future of Elevators
With permanent magnet motors, inverter drive systems, regenerative energy technology, silent mechanical design, and intelligent standby control, modern elevators deliver green, energy-efficient, and comfortable operation—ideal for residential buildings, office towers, hotels, and commercial complexes.
