Abstract:
The disclosure relates to printed circuit board motors and specifically to printed circuit boards used in motors and generators. Windings formed from copper on printed circuit boards have been used for purposes of forming antennas, inductors, transformers, and stators that can be incorporated in permanent magnet brushless DC (permanent magnet synchronous) machines. For energy conversion devices using modern permanent magnet materials and PCB stators, the magnetic field is not strongly confined by magnetically susceptible materials. Thus, the interaction between fields from adjacent turns in a winding, and/or windings on adjacent layers (for a multilayer configuration) may be significant. The structures disclosed hereinafter reduce the effective resistance in the windings, and therefore reduce the associated losses to achieve a reduced current density in portions of the rotating energy conversion devices. The effect of the disclosed structures is a measurable reduction in loss mechanisms as a function increasing frequency, compared to the currently available devices. These effects are significant in frequency ranges important to energy conversion processes as well as typical control strategies, for example, pulse-width modulation.

Abstract:
The border routing of conductive traces in devices, such as displays, touch sensor panels, and touch screens, to improve border area space usage, thereby reducing device size, and to reduce trace resistance, thereby improving device operation, is disclosed. The conductive traces can form a staggered stair-step configuration in the device border area, in which the average widths of the traces can be different from each other and each trace can have segments with different widths. The conductive traces can be coupled to an active area of the device to transmit signals to and from the active area in accordance with a device operation. The varying widths can help improve the border area space usage, reduce trace resistance, and reduce the differences in resistance between traces.
