PRINTED-CIRCUIT BOARD COIL AND MOTOR
First Claim
1. A motor assembly comprising:
- a planar substrate;
a spiral-shaped conductive trace overlying the planar substrate and wound about an aperture; and
a magnetic armature that oscillates within the aperture when an oscillating current is applied to the spiral-shaped conductive trace.

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