STATOR MODULE AND PLANAR DRIVE SYSTEM

The invention relates to a stator module (2) and a planar drive system (1) having such a stator module (2), the stator module (2) having: an upper module face (8) extending in one plane and a lower module face (9) opposite the upper module face (8); a stator unit (400); and a cooling unit (500). The stator unit (400) has at least one coil conductor (402) to which a drive current can be supplied to generate a magnetic field to drive a mover (20), positionable on the upper module face (8), of the planar drive system (1). The stator unit (400) is situated on the upper module face (8). The cooling unit (500) has a housing cover (510) and a housing bottom (520), the housing cover (510) being situated between the stator unit (400) and the housing bottom (520). The housing cover (510) is at least thermally connected, on an upper cover face (553) of the housing cover (510), to a lower stator face (403) of the stator unit (400), and the housing cover (510) is thermally connected, on a lower cover face (554) facing away from the stator unit (400), to the housing bottom (520). The housing bottom (520) is situated on the lower module face (9) and has a first fastening section (556) on the lower module face (9), the first fastening section (556) being thermally connectable to a heat sink (5). The housing cover (510) is designed to conduct heat (W2, W3) out of the stator unit (400) to the housing bottom (520), and the housing bottom (520) is designed to conduct the heat (W2, W3) from the housing cover (510) at least partially to the first fastening section (556). L'invention concerne un module de stator (2) et un système d'entraînement planaire (1) comprenant un tel module de stator (2), le module de stator (2) comportant une face supérieure du module (8), s'étendant dans un plan et une face inférieure du module (9), opposée à la face supérieure du module (8), une unité de stator (400) et une unité de refroidissement (500) ; l'unité de stator (400) comportant au moins un conducteur de bobine (402), pouvant être alimenté en courant sous forme d'un courant de commande, destiné à générer un champ magnétique destiné à entraîner un rotor (20), pouvant être positionné sur la face supérieure du module (8), du système de commande planaire (1) ; l'unité de stator (400) étant agencée sur la face supérieure du module (8) ; l'unité de refroidissement (500) comportant un couvercle de boîtier (510) et un fond de boîtier (520) ; le couvercle de boîtier (510) étant agencé entre l'unité
