Linear guide

Linear guide comprising a guide rail (25) on which a guide carriage (26) is supported for movement longitudinally, and a drive to cause the longitudinal movement of the guide carriage (26), the drive being formed as an electric motor with a first motor element arranged on the guide rail (25) and a second motor element arranged on the guide carriage (26), and a distance-measuring system on the linear guide, which includes a measuring strip (31) and a measuring head (30) movable relative to the measuring strip adjacent to the guide carriage (26) or the guide rail (25) and extending parallel to the guide rail (25), wherein the distance-measuring system includes an acceleration sensor having an eddy current sheet and an exciter block (28) surrounding at least a portion thereof, the acceleration sensor is a sensor operating according to the Ferraris principle, and the eddy current sheet is formed of a non-magnetizable metal, and the eddy current sheet function is performed by a rotating disk which is drivable by the guide rail.

Linear guide comprising a guide rail arranged in a guide housing (35) on which a traveling carriage is supported for movement longitudinally, and with a drive to cause the longitudinal movement of the traveling carriage (36), the drive being formed as an electric motor with a first motor element arranged on the guide rail and a second motor element arranged on the traveling carriage (36), and a distance-measuring system allocated to the linear guide, the distance-measuring system including an acceleration sensor with an eddy current sheet (41) and an exciter block (42) operating according to the Ferraris principle, whereby the eddy current sheet (41) is made of an electrically conducting, non-magnetizable material and the exciter block (42) includes permanent magnets, and whereby the eddy current sheet (41) is part of a beam having a U-shaped cross section which forms a cable channel (39) for a drag chain (38).
