The invention relates to a radial flux permanent magnet elevator motor (10), comprising a motor frame (12) forming the stator frame having fixing points to be fixed to an elevator guide rail (18), which frame (12) has a back wall (16) facing and/or abutting with the guide rail (18), which motor frame (12) comprises an axially extending flange (20) protruding away from the back wall (16) in the direction of the rotor (26), and which motor frame (12) comprises at least one axially extending first wall section (22) in a defined radial distance from the axis of the motor frame (12), which first wall section (22) is configured to support a stator winding (24) of the motor (10); the rotor (26) comprises a central hub (28) protruding into the flange (20) of the motor frame (12) and being rotatively supported within the flange (20) via bearings (30a, 30b), which rotor (26) comprises a traction sheave (32) in a first radial distance from the motor axis and a ring-like support wall (34) in a second radial distance from the motor axis for supporting permanent magnets (36), which second distance is larger than the first distance, and whereby the stator winding (24) and the permanent magnets (36) form a radial air gap.
