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. 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.
