Abstract
A method for producing a round stator includes: inserting wound pole teeth into an insertion section of a rolling device to form a pole tooth row, pushing the pole tooth row into a ring section of the rolling device, which ring section reproduces a round end shape of the stator to form a round stator structure, removing the round stator structure from the rolling device while holding the stator structure together, and processing the stator structure further to form a finished stator unit.
Claims8
A method for producing a round stator, comprising:
- inserting a plurality of lined-up and wound individual pole teeth (6) into an insertion section (3) of a slot (2) of a rolling device (1), the cross-sectional shape of the slot (2) being matched to the cross-sectional shape of a wound pole tooth, to form, from the plurality of individual pole teeth (6), a pole tooth row (10);
- pushing the pole tooth row (10) into a ring section (5) of the slot (2) of the rolling device (1), which pushing of the pole tooth row (10) into the ring section (5) of the slot (2) into the ring section acts on the pole tooth row (10) so that the pole tooth row (10) reproduces a round end shape of the stator to form a round stator structure comprising the pole teeth (6);
- removing the round stator structure from the slot (2) of the rolling device (1) while holding said round stator structure together;
- and
- processing said stator structure further to form a finished stator unit.
A rolling device (1) for forming a round stator, the rolling device (1) for use in a method that includes:
- inserting a plurality of lined-up and wound individual pole teeth (6) into an insertion section (3) of a slot (2) of the rolling device (1), the cross-sectional shape of the slot (2) being matched to the cross-sectional shape of a wound pole tooth, to form, from the plurality of individual pole teeth (6), a pole tooth row (10);
- pushing the pole tooth row (10) into a ring section (5) of the slot (2) of the rolling device (1), which pushing of the pole tooth row (10) into the ring section (5) of the slot (2) into the ring section acts on the pole tooth row (10) so that the pole tooth row (10) reproduces a round end shape of the stator to form the round stator structure comprising the pole teeth (6);
- removing the round stator structure from the slot (2) of the rolling device (1) while holding said round stator structure together;
- and processing said stator structure further to form a finished stator unit, the rolling device (1) comprising:
- the slot (2), the cross section of said slot being matched to the cross-sectional shape of the wound pole tooth (6), and said slot having the insertion section (3) and the ring section (5).
