Zusammenfassung: | The invention relates to an elevator comprising an electric linear motor (14) comprising at least one linear stator (50) designed to be located in a fixed correlation to an environment, particularly building, and at least one mover (24, 26; 126) designed for connection with an elevator car to be moved (16; 16a-16d) and co-acting with the stator to move the car,
which motor comprises a stator beam (18; 114) supporting said at least one stator (50), which stator beam has at least one side face (42-48; 116-124) carrying ferromagnetic poles (52) of said stator spaced apart by a pitch (d), and which mover (24, 26; 126) comprises at least one counter-face (54) facing said side face(s) of the stator beam, in which counter-face electro-magnetic components (70, 71, 72, 74, 76) of the mover (24, 26; 126) are arranged to co-act with the ferromagnetic poles (52) mounted on the stator beam (18), which elevator comprises an elevator brake. According to the invention the side face (42-48) of the stator beam (18) facing the mover and/or the counter face (54) of the mover facing the side face of the stator beam (18) comprise(s) a brake surface (51, 54) which form(s) the brake interface of the elevator brake. |
