A sliding door assembly comprises a door leaf (24) provided with an upper horizontal 5 edge and a lower horizontal edge; an upper guide rail assembly (20, 42) for guiding the upper edge of the door leaf (24) in translation parallel to a horizontal sliding direction (100) relative to the upper guide rail assembly (20,42) between a first end position and a second end position; and one or more rows (28, 30) of first magnetic field generating elements fixed to the door leaf (24) , each of the rows (28, 30) 10 extending horizontally. The one or more rows (28, 30) of first magnetic field generating elements are each located at an intermediate position below the upper horizontal edge and upper guide rail (20, 42) and above a lower horizontal edge of the door leaf. One or more stators (38, 40) each associated with one of the rows (28, 30) of first magnetic field generating elements overlap with one end of the rows (28, 15 30) of first magnetic field generating elements in the first position. Each stator comprises an second magnetic field generating element located at an air gap distance of the associated one of the rows (28, 30) of first magnetic field generating elements for generating an induced electromagnetic force in the sliding direction (100) on the associated one of the rows (28, 30) of first magnetic field generating elements, the 20 one or more stators (38, 40) being stationary with respect to the upper guide rail assembly (20,42).
