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.

A wireless power transfer arrangement for an elevator car of an elevator is presented. The wireless power transfer arrangement comprises primary winding units distantly arranged with respect to each other at first positions of an elevator shaft along which the elevator car is configured to be moved, at least one secondary winding unit arranged to the elevator car. Each one of the primary winding units and the at least one secondary winding unit are arranged so that there is a gap between said winding units for enabling movement of the secondary winding unit with respect to the primary winding units and for establishing an inductive coupling between said winding units whenever said winding units are arranged to face each other at one of the first positions.

Wireless power transfer arrangement for an elevator car and an elevator

A linear flux switching permanent magnet (FSPM) motor includes a longitudinal linear stator with stator teeth facing an air gap and a mover including at least one armature with armature teeth, whereby at least some of said, preferably all of said armature teeth embed at least one permanent magnet, respectively, which armature teeth are spaced apart by slots for receiving an armature winding. The permanent magnets embedded in the corresponding armature teeth protrude by an overhang over the back of the armature in a direction facing away from the air gap.

Linear flux switching permanent magnet motor

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.

Electric linear motor

A linear flux switching permanent magnet (FSPM) motor includes a longitudinal, linear stator with stator teeth facing an air gap and a mover including at least one armature including armature teeth embedding at least one permanent magnet, which armature teeth are spaced apart by slots for receiving an armature winding, and which armature teeth have an extended width portion towards the air gap. The extended width portion of the armature teeth begins in the longitudinal direction of the armature teeth already at the level of the armature windings.

A linear flux switching permanent magnet (FSPM) motor includes a longitudinal linear stator with stator teeth facing an air gap and a mover including at least one armature including armature teeth, which are spaced apart by slots for receiving an armature winding. At least some, preferably all of the armature teeth embed at least two permanent magnets, respectively, which are positioned successively in longitudinal direction of the tooth, whereby the two permanent magnets have different magnetic properties.
