The invention relates to a sliding door comprising a combined magnetic support and drive system for at least one door panel, provided with a permanently excited magnetic support device and a linear drive unit. The inventive support device comprises at least one polarised magnetised row of magnets (1, 1e, 1f) which alternate at determined distances in the direction of driving, at least one soft or hard magnetic support element (2) which is in dynamic effect with at least one of the at least one row of magnets (1, 1e, 1f), and a guide element (3). The guide element ensures a specific gap-like distance between the at least one row of magnets (1, 1e, 1f) and the support element (2a, 2b, 2d). The linear drive unit comprises at least one coil arrangement (7) made of several individual coils (7), said coil arrangement bringing about an interaction with the at least one row of soft or hard magnetic elements (1, 1e, 1f) during the corresponding control of the individual coils, which produce advance forces. The support element (2) comprises at least one support rail (2a-d, 2n, 14b) which is arranged with a first specific distance in relation to a first side of the at least one row of magnets (1, 1e, 1f). The coil arrangement (7) is arranged at a second specific distance in relation to a first side of the row of magnets (1, 1e, 1f) opposite to the second side of the row of magnets (1, 1e, 1f). |
