A drive machine (10) for elevators has a rotatable drive sheave (18) that has an inner surface and an outer surface with at least one groove (34) for receiving a hoist rope. A rotor (36) is attached to the inner surface of the sheave (18). A stator (38) is connected to a fixed hollow shaft (22), wherein the stator (38), rotor (36), and drive sheave (18) are concentrically positioned about a centerline of the fixed hollow shaft (22). A plurality of bearings (42) are placed between the shaft (22) and rotor (36). |
