Linear motors (10) and elevators (100) are presented in this document. A linear motor (10) comprises a stator (20) and a mover (15) adapted to move along the stator (20), one of them (20, 15) comprising non-magnetic core coils (25) arranged in a row (24) in a longitudinal direction (Z). Further, the other of the stator (20) and the mover (15) comprises permanent magnets (28) arranged in at least two adjacent rows (27) in a longitudinal direction (Z), wherein the rows of permanent magnets (27) are separated by a gap(s) dimensioned for receiving the row(s) of coils (24). Still further, at least one of the rows of permanent magnets (27) may be arranged in a form of Halbach array (40). The elevator (100) may comprise an elevator shaft (30) and an elevator car (5) arranged to be moved by the linear motor (10) in the elevator shaft (30).
