An elevator motor includes a stator with stator windings and a rotor including permanent magnets, whereby the magnets of the rotor and windings of the stator are arranged in an axial flux arrangement. The rotor is connected to a traction sheave for driving hoisting ropes of an elevator, whereby the permanent magnets are arranged on a carrier of the rotor in a ring-like arrangement to form a magnet ring with slots in between. The slot width differs between at least some of two successive slots in the magnet ring. This permanent magnet motor has a reduced noise propagation and is particularly adapted for use in residential elevators.

ARRANGEMENT FOR REPLACING ELEVATOR SUSPENSION ROPES AND A METHOD
An arrangement for replacing an elevator suspension rope comprises an elevator shaft; and an elevator with a car, a hoisting machinery, one or more suspension ropes, and a counterweight; the car and the counterweight being suspended by said one or more ropes which are adapted to be guided over a traction sheave comprised by the machinery for moving the car along the elevator shaft; wherein the car and the counterweight are arranged at any vertical height in the shaft when replacing said one or more ropes. A method for replacing an elevator suspension rope in said arrangement.
A method for monitoring elevator suspension rope condition, the elevator comprising: a car; a hoisting machinery with a motor, a traction sheave and a machine brake; one or more suspension ropes; and a counterweight; the car and the counterweight being suspended by said one or more ropes which are guided over a unitary traction sheave or a group of rotatable individual wheels comprised by the traction sheave for moving the car vertically in an elevator shaft; the method comprising a) performing consecutive first and second measurement steps, wherein in the first measurement step: parking the car to a first position in the shaft, in which position a total rope force on car side is selected different from a total rope force on counterweight side, and locking the car vertically immobile in place relative the shaft; enabling the traction sheave or one of the individual wheels to rotate to the direction of larger rope force; recording a first rotation angle difference (Δφ1) of the traction sheave or said one individual wheel; and in the second measurement step: parking the car to a second position in the shaft, in which position a total rope force on car side is selected different from total rope force on counterweight side, and locking the car vertically immobile in place relative the shaft; enabling the traction sheave or said one individual wheel to rotate to the direction of larger rope force; recording a second rotation angle difference (Δφ2) of the traction sheave or said one individual wheel; and b) calculating the rope stiffness based on at least said first and second measurements in at least two different vertical positions; c) indicating rope condition based on changed rope stiffness. An arrangement for monitoring elevator suspension rope condition.

METHOD FOR ENSURING ELEVATOR SAFETY IN ELEVATOR SYSTEM, ELEVATOR CONTROL UNIT, ELEVATOR SYSTEM, AND COMPUTER PROGRAM PRODUCT
A method for ensuring elevator safety in an elevator system, an elevator control unit, an elevator system, and a computer program product are disclosed in this document. The method comprises detecting a foreign object in an elevator shaft during normal operation mode, establishing a safe zone of the elevator shaft, wherein the safe zone is associated with a safe zone speed, a safe distance, and a safe direction, switching operational mode of the elevator system to a safe zone mode, determining that the elevator car is in the safe zone, and allowing movement of the elevator car in the safe zone to the safe direction at a speed not exceeding the safe zone speed.
The invention relates to a method for triggering an acquisition of image data of an empty elevator car. The method comprises obtaining door status data representing a status of the door of the elevator car, obtaining occupancy status data representing an occupancy status of the elevator car, detecting based on the obtained door status data that the door of the elevator car is closed, detecting based on the obtained occupancy status data that the elevator car is empty, and generating a control signal to an imaging device arranged inside the elevator car in response to the detecting that the door of the elevator car is closed and the elevator car is empty. The control signal comprises an instruction to trigger the acquisition of the image data of the empty elevator car. The invention relates also to a triggering system for triggering an acquisition of image data of an empty elevator car and to an elevator system comprising a triggering system.
