Abstract: An elevator system may include a motor having a common shaft which is suitable to engage any one of a plurality of interchangeable drive component assemblies, and a drive component assembly selected from the plurality of different interchangeable drive assemblies and engaged to the common shaft. The plurality of interchangeable drive component assemblies can be a sheave assembly or a sprocket assembly. The motor can be a direct drive motor, e.g., a permanent magnet (PM) brushless motor or a synchronous motor. The plurality of interchangeable drive component assemblies may also include one or more components which are interchangeable between the assemblies, e.g., a manual lowering device (MLD) or a spacer or a hub. The plurality of interchangeable drive component assemblies may each be assembled from a set of pre-configured assembly components configured for use with the common shaft.

Abstract: There is disclosed a flat motor of reduced length and maximized power output and which is suitable to being disposed in a limited space configuration and a close tolerance within other objects which may be present in such limited space.
