When choosing an elevator traction machine, building owners, elevator maintenance companies and elevator installers must consider factors such as efficiency, durability, maintenance costs, and compatibility. Choosing the wrong traction machine can lead to frequent breakdowns, high energy consumption, and high maintenance costs.
The KONE MX18 traction machine is an efficient solution designed for mid- and high-rise elevators. With its energy-efficient motor, long service life, and smooth operation, it is widely recognized as one of the best traction machines available today. But is it right for your elevator system? In this in-depth analysis, I’ll break down its performance, cost-effectiveness, and key technical details to help you make an informed decision.
What Is the KONE MX18 Traction Machine?
The KONE MX18 is a gearless traction machine designed to replace traditional geared motors, increasing efficiency and reducing maintenance requirements. It is widely used in passenger elevators, freight elevators, hospital elevators, and other high-traffic applications.

Key features:
- Gearless PMSM (Permanent Magnet Synchronous Motor) technology for high energy efficiency.
- Compact and lightweight, reducing installation space.
- high load capacity, suitable for medium and high-rise buildings
- Low noise and vibration for a smoother ride.
What Types of Elevators Are Compatible with the KONE MX18?

The KONE MX18 is not a one-size-fits-all solution. It is specifically designed for gearless traction elevators that meet the following criteria:
Suitable for:
- Mid-to-high-rise buildings (up to 100m in height).
- Passenger elevators with a load capacity of 1000kg–1600kg.
- Freight and hospital elevators requiring a smooth, high-precision operation.
- Speeds ranging from 1.75m/s to 3m/s.
- Modernization projects replacing outdated gear-driven traction machines.
Not Suitable for:
- Hydraulic elevators – The MX18 is strictly for traction-based systems.
- Low-rise buildings – Other models with lower power output may be more cost-effective.
- Older elevators with incompatible control systems – Additional modifications may be needed.
