Abstract: An elevator motor includes a stator with stator windings and a rotor including permanent magnets, whereby the magnets of the rotor and windings of the stator are arranged in an axial flux arrangement. The rotor is connected to a traction sheave for driving hoisting ropes of an elevator, whereby the permanent magnets are arranged on a carrier of the rotor in a ring-like arrangement to form a magnet ring with slots in between. The slot width differs between at least some of two successive slots in the magnet ring. This permanent magnet motor has a reduced noise propagation and is particularly adapted for use in residential elevators.
