Abstract

A stator module is disclosed, and a planar drive system with a stator module. The stator module has a lower face opposite an upper face, a stator unit situated on the upper face, and a cooling unit. The stator unit has a coil to which current can be supplied to generate a magnetic field to drive a mover, positionable on the upper face of the stator module. The cooling unit has a cover thermally connected to a lower face of the stator unit and to the bottom of the housing. The bottom of the housing has a first fastening section on the lower face of the stator module, thermally connectable to a heat sink. The cover is designed to conduct heat out of the stator unit to the bottom of the housing, which is designed to conduct the heat at least partially to the first fastening section.
