DRIVE SHEAVE ELEVATOR, ELEVATOR DRIVE FOR SUCH A DRIVE SHEAVE ELEVATOR, AND METHOD FOR OPERATING SUCH AN ELEVATOR DRIVE

摘要

The invention relates to a drive sheave elevator (A) comprising at least one elevator cab (1) and at least one elevator drive (4); wherein the elevator drive (4) comprises at least one stator (41) and at least one rotor (42); which rotor (42) is connected to at least one drive sheave (13); on which drive sheave (13) at least one support means (2) lies in friction closure; which support means (2) is connected to the elevator cab (1) in such a way that a rotational motion of the rotor (42) and of the drive sheave (13) moves the elevator cab (1); characterized in that the rotor (42) is composed exclusively of soft magnetic material.
