A method for determining a speed of an electric motor (2) of an elevator (100) comprising a plurality of phases (30A, 30B, 30C) for supplying electric current to the electric motor (2). The method comprises forming an effective short-circuit between at least two of the plurality of phases (30A, 30B, 30C) of the electric motor (2), determining a short-circuit current, the short-circuit current being the current flowing in the effective short-circuit, and determining the speed of the electric motor (2) based on at least one characteristic of the short-circuit current.
