Abstract
The invention refers to 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 element to be moved and co-acting with the stator, 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 located.
Claims18
Electric linear motor comprising:
- at least one linear stator designed to be located in a fixed correlation to an environment
- a stator beam supporting the at least one stator and having four side faces, wherein at least one side face carries ferromagnetic poles of the at least one stator spaced apart by a pitch (d);
- and
- at least one mover designed for connection with an element to be moved and co-acting to move along the stator, the mover comprises:
- at least one counter-face facing the 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 of the stator beam,
- a C-profile surrounding the stator beam, and
- four counter-faces arranged in a rectangular configuration facing the four side faces of the stator beam, wherein each of the counter-faces comprises the electro-magnetic components of the mover and the opening in the C-profile is configured to accommodate a fastening element to fix the stator beam to an elevator shaft.
