Abstract
Dans le procédé selon l'invention, on comprime radialement la bobine 11 enroulée cylindriquement et placée sur un mandrin lisse 12. La compression est effectuée à l'aide de matrices 13 que l'on rapproche l'une de l'autre et dont les surfaces intérieures 13a viennent s'appliquer contre la surface latérale de la bobine en comprimant les couches de spires et en déformant le fil. On obtient des bobines très minces à forte densité de spires, grâce à quoi on peut fabriquer des moteurs compacts et plus puissants.
