A wireless power transfer arrangement (200) for an elevator car (110) of an elevator (100) is presented. The wireless power transfer arrangement (200) comprises primary winding units (210) distantly arranged with respect to each other at first positions (250) of an elevator shaft (130) along which the elevator car (110) is configured to be moved, at least one secondary winding unit (220) arranged to the elevator car (110). Each one of the primary winding units (210) and the at least one secondary winding unit (220) are arranged so that there is a gap (215) between said winding units (210, 220) for enabling movement of the secondary winding unit (220) with respect to the primary winding units (210) and for establishing an inductive coupling between said winding units (210, 220) whenever said winding units (210, 220) are arranged to face each other at one of the first positions (250).
