Definitions

  • the present invention relates to a drive device, and in particular to a drive device comprising a roll used in, e.g., fibre machine.
  • variable reluctance motor including a stator and a rotor, wherein the rotor comprises salient poles, and the roll comprises a shaft part and the rotor.
  • Fig. 4 shows a sectional view in longitudinal direction of a roll according to a third embodiment
  • the number of rotor poles is not the same as that of the rotor poles (typically less) .
  • the stator can be made of segments. The stator can operate only on a part of the rotor circle. Those parts of the rotor, which are not close to the stator, are passive roll or shaft parts without having any magnetic pull. This latter case is not possible if a permanent-magnet rotor is used.
  • Fig. 1 shows a first embodiment for a drive device according to the present invention.
  • a roll 10 is shown, which comprises a rotor part 10A and a shaft part 10B.
  • the shaft part 10B and the rotor 10A are provided as one piece, i.e. are integrally formed.
  • salient poles (also referred to as teeth) 30A are formed, which are indicated in the drawing by a hatched area.
  • the roll 10 can easily be formed by machining.
  • Reference number 20 denotes the stator of the variable reluctance motor, wherein according to the present embodiment the rotor is provided inside the stator.
  • the rotor section is not magnetic nor vulnerable to corrosion or temperature
