摘要： A guide device (26) for use in an elevator system includes an elevator guide roller (30) having a hardness that varies depending on a speed of rotation of the guide roller (30). In a disclosed example, a magnetorheological fluid within the guide roller (30) changes viscosity depending on the speed of rotation. One example includes varying an influence of a first magnetic field on the magnetorheological fluid to change the viscosity.

摘要： 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. In a disclosed example, distinct first and second stator core portions are formed. The stator core portions in disclosed examples are made from laminations or sintered powder materials. In a disclosed arrangement, a coil is supported between the core portions of the stator such that the core portions enclose at least part of axial surfaces on the coil. A rotor that has a core and a plurality of magnets is supported relative to the stator for relative rotary motion such that the plurality of magnets of the rotor interact with the stator core portions during the relative rotary motion.

摘要： 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.
