Description

Alberto Sassi G-525 All World Elevator Traction Machine by Alberto Sassi is a professional elevator traction machine suitable for projects where Italian engineering, dependable torque delivery and long service life are required. It is especially suitable for MRL and machine-roomless traction elevators where compact dimensions, quiet running and energy-efficient operation are important. The unit is intended for integration with modern elevator control systems and VVVF drives, supporting accurate speed regulation, controlled start/stop performance and low vibration operation. Its configuration helps installers select the correct roping arrangement, sheave diameter and capacity according to shaft layout, cabin load, traffic demand and project standards. Nazar Elevator can supply this model as part of complete elevator packages, modernization solutions or component-based export orders. Final sizing must always be confirmed according to shaft dimensions, duty load, speed, suspension ratio, safety factor, brake configuration and local code requirements.

What is a gearless traction machine?

The Alberto Sassi G-525 All World is a gearless elevator traction machine. A gearless machine couples a permanent-magnet motor directly to the drive sheave, with no gearbox between them — which removes the largest source of energy loss, gear oil maintenance and mechanical noise found in geared systems.

Gearless machines are the standard choice for machine roomless (MRL) elevators and for installations where quiet running and low energy consumption are specified. Nazar Elevator supplies the Alberto Sassi G-525 All World to elevator contractors and distributors worldwide.
