Abstract

Le problème à résoudre dans le cadre de la présente invention est d’avoir un moteur linéaire adapté en tant que source motrice pour un appareil ayant deux éléments effectuant un mouvement alternatif de manière rectilinéaire. La solution proposée consiste en des espaces de réception de moteurs (1a, 1b) pour recevoir des moteurs (2a, 2b) d’une manière alternative et rectilinéaire qui sont formés au niveau de positions prédéterminées d’un stator (1). Chacune des bobines (1c, 1d) est disposée au niveau d’une position prédéterminée sur un des côtés qui intercale un espace de réception de moteur correspondant (1a, 1b) et une saillie orientée vers l’intérieur (1e, 1f) pour guider le passage d’un flux magnétique généré par la bobine (1c, 1d) est disposée au niveau d’une position prédéterminée de l’autre côté.
