Abstract: A method and apparatus for self-commissioning a bearingless-motor drive, which includes a bearingless motor and a control unit of the bearingless motor are disclosed. The motor includes at least one winding and at least one permanent magnet. The method includes generating a magnetic model, the magnetic model including a plurality of constant parameters; supplying, while the movable part remains standstill, to the at least one winding at least two unequal currents; measuring, with a magnetic sensor, flux linkages caused by said at least two unequal currents, respectively; calculating, with the magnetic model, flux linkages by inputting to the magnetic model current values equal to the currents supplied to the at least one winding; and fitting, with a least-squares fitting algorithm, at least one constant parameter in the magnetic model such that the difference between the measured and calculated flux linkages will be minimized.

Abstract: The invention refers to an electric linear motor comprising a longitudinal stator beam; at least one mover 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, wherein the at least two side faces, as well as the at least two counter-faces facing the respective side faces, are inclined or offset with respect to each other.

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.

Abstract: A computer-implemented method to manage a device is described. Communications with an endpoint device are established. A management profile for the endpoint device is received. Information about the endpoint device is acquired based at least in part on the management profile. At least a portion of the acquired information is provided to an upper layer server.

Abstract: A computer-implemented method for managing access to a peripheral device is described. A request is received from an operating system to interface with a peripheral device. The operating system requesting to interface with the peripheral device is analyzed. A determination is made as to whether the operating system is a host operating system based on the analysis of the operating system. The operating system is prevented from interfacing with the peripheral device if the operating system is a host operating system.
