An elevator installation has an elevator car that is moved in an elevator shaft between floors of a building under control of an elevator controller. The car has a first car door on a first car wall and a second car door on a second car wall. A first group of shaft doors is arranged in public zones of the building and a second group of shaft doors is arranged in non-public zones of the building. The elevator controller has a first operating mode in which the public zones are served; accordingly, only the first car door and the shaft doors for the public zones are actuated. In a second operating mode, the non-public zones are served, and accordingly only the second car door and the shaft doors for the non-public zones are activated.

Methods for determining an absolute position of a moving travel unit of a stationary transport system, the travel unit movable along a travel path inside the system. The travel unit is driven by at least one linear motor along the path. The linear motor is a synchronous motor including a plurality of stator units installed along the travel path configured to provide a magnetic field traveling along the travel path. At least one rotor unit is attached to the travel unit and is configured to be driven along the travel path by the traveling magnetic field. Wherein respectively by analysis of regulating parameters of a vector regulation of the linear motor an active stator unit is determined from the plurality, which presently provides the magnetic field driving the rotor unit and a relative position of the rotor unit in relation to the active stator unit is computed.

According to an aspect, there is provided a method for determining the number of elevator cars in a two-shaft multi-car elevator system. The method comprises determining the number of active elevator cars N in the two-shaft multi-car elevator system by $N=\frac{\mathrm{RTT}*\mathrm{arr}}{a*\mathrm{carsize}},$
wherein RTT is a round trip time of the two-shaft multi-car elevator system, arr is the arrival rate of passengers, a is a car load factor, and carsize is the number of passengers one elevator car is able to carry.

The invention relates to an elevator comprising an electric linear motor comprising at least one linear stator designed to be located in a fixed correlation to an environment, particularly building, and at least one mover designed for connection with an elevator car to be moved and co-acting with the stator to move the car, which motor comprises a stator beam supporting said at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch, and which mover comprises at least one counter-face facing said side face(s) of the stator beam, in which counter-face electro-magnetic components of the mover are arranged to co-act with the ferromagnetic poles mounted on the stator beam, which elevator comprises an elevator brake. According to the invention the side face of the stator beam facing the mover and/or the counter face of the mover facing the side face of the stator beam comprise(s) a brake surface which form(s) the brake interface of the elevator brake.

An elevator controller detects a malfunction such as elevator blockage in an observed elevator utilizing a method including: acquiring first data during an application phase, the first data correlating with at least one condition in the observed elevator; acquiring further data during the application phase, the further data correlating with the at least one condition in other elevators; determining a current relative behavior of the observed elevator during the application phase based on a comparison of the first data with the further data; and detecting the malfunction in the observed elevator based on an analysis of the current relative behavior. The normal relative behavior information of the observed elevator, learned in a machine learning procedure during a preceding learning phase, is taken into account upon analyzing the current relative behavior of the observed elevator. The method enables automatically detecting malfunctions in an elevator while reducing a probability of false alarms.
