Alberto Sassi G300-T2 Gearless Elevator Machine
The Alberto Sassi G300-T2 is an Italian gearless elevator traction machine designed for MRL and modern traction elevator systems requiring quiet operation, precise control and efficient performance.
Description
What is a gearless traction machine?
The Alberto Sassi G300-T2 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 G300-T2 to elevator contractors and distributors worldwide.
