Abstract:
An electrical direct linear drive device, with a stator (10) having two guide rails (12, 13) for the linear guidance of a driven carriage (11) is proposed, wherein a permanent magnet arrangement (18) providing the electrical drive, and a drive coil arrangement (19), which is movable relatively thereto, are provided. The guide rails (12, 13) are arranged on sides (14, 15) of the stator (10) which are differently oriented, wherein the carriage (11) extends at least partially over each one of these sides (14, 15). Guide elements having guide channels for the guide rails (12, 13) are arranged on the carriage (11).
