  • Elevator having a drive machine with a rotating traction sheave between multiple motors along the axis of rotation
    Patent number: 6367587
    Abstract: An elevator drive machine includes multiple electric motors and a traction sheave. The traction sheave is placed between the motors. With this arrangement, a higher torque is generated by the drive machine as compared to conventional solutions. Furthermore, an elevator arrangement in which such a drive is utilized exhibits efficient space utilization.

  • Elevator drive machine having rotating part positioned between two rotors along the axis of rotation
    Patent number: 6220395
    Abstract: An elevator drive machine includes a drive machine frame structure, a rotating part rotatably supported by bearings on the frame structure and having a traction sheave, and an electromechanical apparatus for driving the rotating part. The bearings of the rotating part include a bearing that substantially only transmits radial forces between the rotating part and the frame and a bearing that transmits axial forces between the rotating part and the frame.

  • Procedure for adjusting air gaps between rotors and stators in an elevator drive machine
    Patent number: 6202794
    Abstract: The invention relates to a procedure for setting the magnitudes of the axial air gaps and/or the mutual positions of the rotors and stators defining the axial air gaps in a gearless elevator drive machine comprising an electromechanical apparatus having two axial air gaps. In the procedure, the size of the axial air gap and/or the positions of the rotors and stators is/are adjusted based on a selected property, e.g. a current or voltage property.

  • Elevator drive machine
    Patent number: 6199666
    Abstract: An elevator drive machine includes a traction sheave and an electromechanical apparatus having at least two electric motors for driving the traction sheave. The traction sheave and the weight applied to it via the elevator ropes are supported by bearings between the stators and rotors of the electric motors driving the traction sheave of the drive machine.

  • People mover and drive apparatus
    Patent number: 6161674
    Abstract: A people mover such as an escalator or moving sidewalk is driven by a motor having a relatively small axial dimension and is configured to fit in available space, avoiding the need for a machine room for these components, thereby simplifying the incorporation of the people mover into a new or existing building design.
