Gearless Traction Machine
What is Gearless Elevator Traction Machines ?
The machine that manages all of the moving parts is a gearless machine, it has a drive sheave, deflector sheave, dual brake system and direct-drive permanent magnet alternating current (AC) motor. The gearless machine will have its wheel attached directly onto the electric motor to instantly rotate the drive sheave. As the drive sheave rotates, the elevator cab will raise and lower accordingly. The simplest and quickest way to tell a gearless machine from a geared machine is to check if everything is running in the same direction.
