Abstract
An elevator includes at least one elevator shaft and at least one elevator car traveling in the elevator shaft. The elevator has at least one elevator motor including at least one linear stator located vertically along the elevator shaft and at least one mover located in connection with the elevator car and co-acting with the stator. The elevator includes a vertical stator beam supporting at least one stator, which stator beam has at least one side face carrying ferromagnetic poles of said stator spaced apart by a pitch. The mover includes at least one counter-face facing the side face(s) of the stator beam, in which electro-magnetic components of the mover are located.
