Sicor SGS7 Gearless Elevator Traction Machine

Sicor SGS7 is a professional Italian gearless traction machine for modern elevator systems with or without a machine room. The SG/SGS gearless range uses a permanent-magnet synchronous motor, safety brake, encoder feedback and a compact traction unit to deliver high energy efficiency, low vibration and excellent cabin comfort. Depending on the configuration, it can be applied to MRL elevators, machine-room modernization projects and compact shaft layouts. The model is suitable for contractors and building projects that need a reliable European gearless drive with flexible traction sheave options and EN 81-oriented safety design. For Nazar Elevator package solutions, Sicor SGS7 can be presented as a premium traction unit for smooth, efficient and technically advanced lift operation. Final selection must be validated with the official configuration table.

What is a gearless traction machine?

The Sicor SGS7 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 Sicor SGS7 to elevator contractors and distributors worldwide.
