Eker QUIET QS-4 Gearless Elevator Traction Machine
Eker QUIET QS-4 is a gearless elevator traction machine from the QUIET series, designed for compact MRL lift systems with efficient and low-noise operation.
Description
What is a gearless traction machine?
The Eker QUIET QS-4 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 Eker QUIET QS-4 to elevator contractors and distributors worldwide.
