A linear motor includes a stator and a mover adapted to move along the stator, one of them including non-magnetic core coils arranged in a row in a longitudinal direction. The other of the stator and the mover includes permanent magnets arranged in at least two adjacent rows in a longitudinal direction. The rows of permanent magnets are separated by a gap(s) dimensioned for receiving the row(s) of coils. At least one of the rows of permanent magnets may be arranged in a form of a Halbach array. The elevator may include an elevator shaft and an elevator car arranged to be moved by the linear motor in the elevator shaft.
