Definitions

  • the ohmic resistors 10 and 12 are implemented as resistance paths, each consisting of a wound around a winding axis A metal wire.
  • the third disc-like winding portion 19c ' is in Fig. 4 like all other disc-like winding sections of this Winding schemes from radially inward to radially outward with respect to the winding axis A wound.
  • the transition between two adjacent disk-like winding sections 19a ', 19b' is effected by a shortened spiral winding 21, which runs between the two disk-like winding sections from radially outside to radially inside (see Fig. 5 ).
  • This shortened winding comprises in the present example only a single turn.
  • the second edge 42 of the sector-shaped cutout 39 does not extend in the radial direction to the winding axis A, but is offset in the radial direction to the longitudinal axis A and has a curvature, which is the greater, the further it is in the radially inner region of the support body 37.
  • the radially innermost portion 43 of the edge 42 corresponds in its curvature approximately to the curvature of the winding 21 of the shortened spiral between two adjacent disc-like winding sections 19 in this area. In this way, the edge 42 can serve as a guide for the radially inner portion of the winding 21.
