Abstract: A stator module for electromagnetically driving a rotor of a planar drive system comprises a connection module to provide drive energy. A power module has a current-generating unit to generate a drive current, which drives the rotor, from the drive energy. A stator unit has a coil conductor, to which the drive current can be applied, for generating a magnetic field which drives the rotor. A sensor module comprises a position-detecting unit to detect a position of the rotor over the sensor unit. The sensor module is arranged in a module housing. The stator unit and power module are arranged on a top side of the module housing and the connection module is arranged on a bottom side. The current-generating unit and the connection module are connected via a drive energy line. The drive energy line passes through the module housing in a manner electrically insulated from the sensor module.
