Abstract: An elevator machine (12) has a plurality of identical transverse flux rotor/stator modules (28-30) of a generally cylindrical configuration arranged contiguously on a common shaft (21) to provide torque to the shaft equal to the torque capability of the modules times the number of modules. A disc brake (49) is integrated with the motor; a two-sided brake disc (49) has friction pads (92, 93) on both sides, braking force being applied to motor end plate (14) and through the brake disc to a stator (60) of one phase (30) of the motor. A process (113) forms variously-sized motors from identically sized modular components, in various configurations (12, 100, 110).

Abstract: Transverse flux electric motors are made using a unique process where individual components are premade and then assembled together. A stator portion is made by nesting a coil between two stator core portions. The stator core portions are made from laminations or sintered powder materials. A separate rotor portion is provided with a core and two permanent magnets that interact with projections on the stator core portions. In one example, the stator includes support members that support additional magnetic core portions to magnify the magnet flux density in the air gap between the stator and the rotor.
