The invention relates to a linear motor for a linear drive mechanism of a magnetic levitation transport system. Said linear motor comprises a plurality of inductor supports (15) which are arranged in a row and which have grooves (14) crosswise to the longitudinal direction, said grooves being substantially equal distances apart from each other; and at least three linear motor lines (1, 2, 3), which are wound into windings (16) in a meandering shape and which are located in the grooves (14) in sections. Said coils (16) have winding heads (16.1, 16.2, 16.3) situated a distance (A) apart. The invention solves the technical problem of producing the windings continuously and economically by providing that the lengths (A') of the winding heads (16.1', 16.2', 16.3') of the at least three linear motor lines (1, 2, 3) are extended at a point of discontinuity (100) between two adjacent inductor supports (15).

L'invention concerne un moteur linéaire pour l'organe d'entraînement linéaire d'un train à sustentation magnétique, comportant une pluralité de supports d'inducteurs (14) qui sont alignés et présentent, transversalement à l'axe longitudinal, des rainures (14) situées à des distances pratiquement constantes les unes des autres. Ce moteur linéaire comprend également au moins trois lignes (1, 2, 3) qui sont enroulées en forme de méandres pour former des enroulements (16) et sont placées au moins en partie dans les rainures (14). Les enroulements (16) présentent des têtes d'enroulement (16.1, 16.2, 16.3) situées dans l'intervalle (A). L'invention vise à permettre une production continue et économique des enroulements. A cet effet, les têtes d'enroulement (16.1', 16.2', 16.3') des lignes de moteur linéaire (1, 2, 3) présentent une longueur (A') accrue en un point de discontinuité (100) entre deux supports d'inducteurs voisins (15).
