    摘要: A smoothing roll for an apparatus for smoothing plastic foils and plates is driven directly by a rotor coaxially received with a stator in an outer housing with the rotor supported by a bearing on the outer housing or on a part of the housing extending coaxially into the rotor. The vibration-free arrangement eliminates chatter marks on the smoothed product.

    摘要: In an electrical heating apparatus having at least one heating body with a chemically substantially resistant sheathing surrounding same, the sheathing comprises at least two-layer co-extruded material. The material comprises an inner layer which in the position of use is towards the heating body and which comprises a material that is a good conductor of heat. Arranged on the outside of the inner layer is an outer layer of chemically substantially resistant and electrically non-conductive material. The inner layer and the outer layer are homogeneously fused together without air inclusions.

    摘要: A method of determining the rotational speed of a three-phase brushless DC-motor, which comprises scanning at least one signal trace disposed on a revolving rotor of a three-phase brushless DC-motor by means of three sensors, each emitting a signal having two possible signal states, the signal trace and the sensors being of such construction and arrangement that eight values are realized by a logical combination of the two possible signal states, respectively, of the three sensors; detecting the rotor position with six of the values; and determining the rotational speed with the other two values.
