An elevator drive for controlling an elevator system has an electric motor with a housing, the electric motor being a permanent magnet synchronous motor. The electric motor has a motor shaft that, on an axial portion of the shaft lateral surface outside the housing, has a drive zone for coupling to at least one support means of the elevator system. A ratio of a weight of the elevator drive to a nominal payload for which the elevator drive is designed is less than 0.2.
