Abstract: A drive system in the form of a torque motor, comprising a stator (1), a rotor (3) and exciter coils (2) on the stator and permanent magnets (4) on the rotor (3), the magnets being located radially opposite one another across an air gap such that electrical excitation of the exciter coils (2) creates magnetic fields extending across the gap and rotating the rotor (3) relative to the stator (1), characterized in that, with the drive system arranged/oriented for normal operation and with the rotor (3) located on the inside, a lower half of the stator (1) has a smaller number of exciter coils than an upper half and, with the stator (1) located on the inside, the upper half of the stator (1) has a smaller number of exciter coils than the upper half.

Abstract: A radial or axial bearing has plastic casing rings formed as strips whose ends form junctions offset from those of the spring rings and/or race rings received in grooves and beds of the casing rings on which the bearings ride.

Abstract: A bearing utilizing a plurality of wires has the races for the roller bodies provides individual lining strips between each wire and the groove walls of the receiving structural members of the bearing. These lining strips are braced in two mutually perpendicular directions against two mutually perpendicular countersurfaces of the grooves and a yieldable connection can be provided between the pair of lining strips in one or both of the grooves so that the bearing prestress and play can be adjusted.
