Abstract: The invention relates to a plug (10) for fastening to hollow or panel-type building materials and to solid building materials. The invention proposes providing the plug (10) with expansion limbs (18) that extend longitudinally and that are connected to one another by thin skins (22) having a corrugation in the peripheral direction. That has the advantage of good screw guidance and a torsionally rigid construction of the plug (10); especially when fastening to hollow and panel-type building materials, undesirable backwards rotation of the plug tip (16) is avoided when screwing in an expansion screw by hand. Angled slits (32) in the plug tip (16) bring about good adaptation to screws having different diameters and different pitches of thread.

Abstract: Disclosed is an electric motor system with reduced torque ripple comprising a sinusoidally magnetized permanent magnet, a sinusoidal inverter, a higher resolution position sensor, a composite iron stator yoke, a composite reinforced plastic rotor core and shaft; and a high gear ratio gear reduction box. The novel combination of magnet, inverter, sensor, plastic rotor core and shaft and high gear ratio gear box substantially reduces the torque ripple on the shaft of said motor system.

Abstract: An analog angle encoder includes a non-magnetic stator which is cup-shaped, having a central post carrying at least one magnetosensitive device, and further including a rotor in the form of a ring captured by the stator, the rotor carrying at least one permanent magnet, wherein the rotor is rotatable relative to the stator. As the rotor rotates relative to the stator, the angle of the incident magnetic field changes relative to the magnetosensitive device, thereby causing the output from the device to vary sinusoidally with angular position. It is preferred to use magnetic configurations other than simple six sided magnets in order to achieve a more uniform magnetic field at the magnetosensitive device, as for example by utilizing cylindrical magnets, arcuate (concave faced) magnets, flat ferromagnetic layer pole pieces, arcuate (concave faced) ferromagnetic layer pole pieces, and ferromagnetic return paths.

Abstract: An apparatus for controlling the load dump voltage of a permanent magnet (PM) alternator having a silicon controlled rectifier (SCR) bridge. The apparatus includes a voltage divider, a peak detector, and a comparator. The voltage divider attenuates the bridge output voltage, which is further fed through a peak detector to hold the peak value for improved stability. The comparator changes states when the bridge output exceeds a predetermined voltage level (e.g., 55 volts) that is less than the load dump threshold limit (e.g., 60 volts), but greater than the normal operating voltage (e.g., 42 volts). The comparator output change-in-state deactivates a gate pulse generator, thereby suppressing further operation of the SCR bridge. Voltage transients that may otherwise occur at the bridge output for the remainder portion of a half cycle from the PM alternator are clamped using a varistor or zener diode.

Abstract: The invention relates to an expansible fixing plug (10), which is manufactured as a two-material fixing plug from a relatively soft and a relatively hard plastics material. To achieve a low insertion torque of an expansion screw as the expansible fixing plug (10) is expanded, yet nevertheless a high anchoring force, the invention proposes constructing from the relatively hard plastics material expansion fingers (22), having cross-sectional areas increasing in size in the direction towards the leading end of the expansible fixing plug (10), which expansion fingers are embedded in expansion tongues (14) of the relatively soft plastics material having a cross-section corresponding to a circular segment, the expansion tongues (14) being connected with one another by dilatation zones (16). (FIG. 8).

Abstract: An expansible plug has a plurality of expansible tongues which extend over an expansible region and are expandable radially away from one another under the action of an expanding member, the expansible region being radially oversized.

Abstract: A voltage mode control method and apparatus for extending speed range operation from a sinusoidally excited permanent magnet motor is described. The method includes a determination of a maximum value from a first set of parameters with each parameter having a known maximum value as well as a reading of a second set of parameters. A computation of a first derived angle using the first set of parameters and the second set of parameters is then performed. A computation of amplitude of phase voltage and a second derived angle using the first derived angle follows. A resultant output comprising a set of derived command voltages for controlling a power circuit is created whereby the power circuit can achieve required torque levels with lower currents for power switches.
