Building Height
The taller the building, the faster the elevator must travel. This allows passengers to reach their destinations quickly. For instance, a 10-story office building might only require an elevator with a speed of 1.5 m/s, while a super-tall building over 300 meters must be equipped with ultra-high-speed elevators exceeding 5.0 m/s or even surpassing 10 m/s. Otherwise, the time spent on vertical transportation would become unbearable.
Passenger Flow
Elevator design speeds also vary based on the building’s purpose and passenger volume. For instance, villa elevators, used infrequently, typically operate at 0.4 m/s, while high-traffic office buildings and shopping malls require faster speeds to meet passenger demands.
Elevator Purpose
Different elevator types often have distinct design speed requirements. Freight elevators and hospital elevators, designed for heavier loads, generally do not exceed 1.0 m/s, whereas passenger elevators operate at higher speeds.
The Technology Behind Elevator Speed
An elevator’s speed isn’t chosen at random — it’s determined by how the system is built, just like how a sports car performs differently from a regular sedan.
The key factors that define an elevator’s speed include the traction machine, control system, guide rails, and safety components.
| Component | Low-Speed Elevator (≤ 1.75 m/s) | High-Speed Elevator (≥ 2.5 m/s) |
| Traction Machine | Geared traction machine or small permanent magnet synchronous motor. | Gearless permanent magnet synchronous traction machine with higher power and efficiency. |
| Control System | Basic variable frequency or older control system. | Advanced VVVF control with smooth acceleration and deceleration. |
| Guide Rails | Standard T-shaped rails with moderate rigidity. | Heavy-duty rails with very high installation accuracy to ensure stability at high speeds. |
| Safety System | Standard governor, safety gear, and mechanical buffers. | High-performance governor and safety gear with faster response; may include hydraulic or energy-absorbing buffers. |
| Car Design | Standard structure with little aerodynamic consideration. | Aerodynamic design and tight sealing to reduce wind noise and vibration. |
| Compensation Device | Simple compensation chain. | Tensioned compensation cable system to balance the weight of main ropes in tall buildings. |
| System | — | Intelligent group control for direct stopping and precise leveling. |
| Cost | Lower | Higher |
