摘要: The present document discloses motors and motor components that are constructed on a planar substrate. In some implementations, the substrate is made from rigid or semi-rigid sheet material, such as printed circuit board (“PCB”). One more coils formed using spiral-shaped conductive traces overlay front and/or back surfaces of one implementation, plurality alternating right-hand left-hand separated by insulating layers, connected with vias to form inductive coils. Alternative coil-configurations include single-drive counter-wound having central ferrous magnetic core.
