    Abstract: A linear motor includes a stator and a mover adapted to move along the stator, one of them including non-magnetic core coils arranged in a row in a longitudinal direction. The other of the stator and the mover includes permanent magnets arranged in at least two adjacent rows in a longitudinal direction. The rows of permanent magnets are separated by a gap(s) dimensioned for receiving the row(s) of coils. At least one of the rows of permanent magnets may be arranged in a form of a Halbach array. The elevator may include an elevator shaft and an elevator car arranged to be moved by the linear motor in the elevator shaft.

    Abstract: An electromagnetic brake comprises an electromagnet arranged about a central axis SA; a slide movable with respect to the electromagnet in a slide actuation direction upon actuation of the electromagnet, and an air gap provided between the electromagnet and the slide through which a magnetic field passes when the electromagnet is actuated, wherein the slide is arranged radially inside or outside of the electromagnet with respect to the central axis SA. The electromagnetic brake is silent.

    Abstract: 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.

    Abstract: The invention refers to an electric linear motor, control apparatus, transport system and a method. The electric linear motor comprises a longitudinal stator beam; at least one mover at least partially surrounding the stator beam and adapted to move along the stator beam; which stator beam comprises at least two side faces located at opposite sides of the stator beam, each of the side faces carrying ferromagnetic poles spaced apart by a pitch, and which mover comprises at least two counter-faces facing the respective side faces of the stator beam. The mover has in at least one of said counter-faces rotor units having at least one winding and at least one permanent magnet arranged to co-act with the ferromagnetic poles of the respective side faces of the stator beam. The ferromagnetic stator poles of the stator beam and the rotor units of the mover are used for generating propulsion forces for driving the mover along the stator beam as well as for generating attraction forces to levitate the mover around the stator beam while driving.

    Abstract: A radial flux permanent magnet elevator motor includes a motor frame forming the stator frame having fixing points to be fixed to an elevator guide rail, which frame has a back wall facing and/or abutting with the guide rail, which motor frame includes an axially extending flange protruding away from the back wall in the direction of the rotor, and which motor frame includes at least one axially extending first wall section in a defined radial distance from the axis of the motor frame, which first wall section is configured to support a stator winding of the motor. The rotor includes a central hub protruding into the flange of the motor frame and is rotatively supported within the flange via bearings, which rotor includes a traction sheave in a first radial distance from the motor axis and a ring-like support wall in a second radial distance from the motor axis for supporting permanent magnets, which second distance is larger than the first distance, and whereby the stator winding and the permanent magnets form a radial air gap.
