    Abstract: A decelerating apparatus includes a brake member, primary and secondary permanent magnets and pole pieces. The primary permanent magnets are arranged in a circumferential direction to face an inner or outer peripheral surface of the brake member with a gap in between. Each of the primary permanent magnets has two opposite magnetic poles arranged in a radial direction. The secondary permanent magnets and the pole pieces are placed in the gap and arranged in the circumferential direction. Each of the secondary permanent magnets has two opposite magnetic poles arranged in the circumferential direction. Each of the pole pieces is positioned between adjacent secondary permanent magnets. Magnetic pole arrangements of adjacent primary permanent magnets are opposite to each other. Magnetic pole arrangements of adjacent secondary permanent magnets are opposite to each other. Each of the secondary permanent magnets has a trapezoidal cross-sectional shape including an upper base and a lower base.

    Abstract: The subject matter of the invention relates to a method and system for energy absorption designed for use in particular in exercise apparatuses, and especially in the so-called fitness equipment.The method for energy absorption consisting in that suitable current load values are selected in order to balance the kinetic energy expended by the person performing exercises with the energy absorbed by the system (100) for energy absorption, wherein the value of current load, which is selected by a computer (PC), is dependent on the psychomotor parameters of the person performing exercises.The system (100) for energy absorption is provided with a variable current load circuit (150) connected to an element (S) producing direct current (DC) or alternating current (AC) electric energy, which is controlled by the computer (PC). The system (100) is also provided with a real-time counting/positioning circuit (120) incorporated between the element (S) producing direct current (DC) or alternating current (AC) electric energy and/or a mechanical system (UM), and the computer (PC).

    Abstract: Systems and methods are described for providing a magnetic clutch to limit Z-directional motion of a mass (e.g., a carriage for transporting a robotic mechanism in context of a storage library). According to embodiments, the mass is suspended by cabling, and its Z-directional movement is controlled by a Z-drive assembly. The Z-drive assembly includes a drive gear made of a magnetic or conductive material, and the drive gear is in magnetic communication with a biasing magnet. Embodiments configured the biasing magnet with a particular magnetic moment and a position relative to the drive gear, so that the spinning of the drive gear induces magnetic currents that tend to counteract the motion of the gear. For example, in the event of power loss to the Z-drive assembly, magnetic clutching is used to limit or prevent motion of the mass under the force of gravity.

    Abstract: A circuit arrangement, especially for supplying an electromagnetic holding brake with a clocked supply voltage, includes a module for controlled provision of a clocked supply voltage for free-wheeling operation of the holding brake. The module has a switching unit for switching off the supply voltage for braking operation. A free-wheeling diode and a suppressor diode are connected in parallel to an inductance of the holding brake, with the free-wheeling diode being effective in free-wheeling operation only and the suppressor diode being effective in braking operation only.
