Abstract: A compact electrical motor (10) especially suitable for being used for applications that do not require a constant revolution speed and a precise position control comprising a rotor (24), a stator (26), at least one electrical winding (28) and at least one further electrical winding (30) arranged coaxially to said stator (26), a shaft (18) whereto the rotor (24) is fixed, with said motor powered in alternating current, with constant number of revolutions and frequency synchronized.

Abstract: An anchorage structure and method for positioning cables in an excavated hole, comprises a plurality of cables adapted to be subjected to a tensioning load having common ends arranged in the hole and disposed in substantially a common plane. A plate having a plurality of bores therethrough through which the ends of the cables extend is secured to the cables so that the plate is positioned substantially parallel to the plane of the common ends of the cables. A resinous mass encases the plate and the cables in an area above and on all sides of the cables, adjacent the ends thereof, leaving a remaining space in the hole around the mass and above and below the mass and concrete filled into the hole in the remaining space. Each of the cables has a coating for insulating them from the concrete and permitting an individual sliding movement of the cables.
