Patent ID: 10141805

Abstract:
Designs and method of construction for planar stators useable inter alia for axial air-gap electric machines are provided. In some embodiments these designs make highly efficient use of the space occupied by the stator, substantially filling most of its volume with active conductors. Some embodiments comprise at least one flexible conductor member (e.g. a flat cable) periodically bent by about 180° to form both external and internal peripheries of a two-layer planar stator. In some embodiments disk-like or ring-like members are used to shape and/or to secure the flexible conductor. In some embodiments adhesive members and/or encapsulating and/or potting of conductive elements provide solidity and rigidity of the stator(s). In some embodiments a plurality of planar stators are interleaved with a plurality of planar rotors, producing an efficient system electrical motor and/or generator.
