STRUCTURES AND METHODS FOR CONTROLLING LOSSES IN PRINTED CIRCUIT BOARDS Russian patent published in 2020 - IPC H02K3/26 

FIELD: printing equipment.

SUBSTANCE: invention relates to motors with printed circuit boards and, in particular, to printed circuit boards used in motors and generators. Said technical result is achieved due to that structure of stator of electric motor or generator includes planar multilayer structure (PCS), having at least one dielectric layer and multiple current conducting layers, wherein PCS is characterized by a central starting point and periphery. Stator can also include a plurality of first elements, radially extending conductive paths which extend from inner to outer radial distance, radii are measured from the central initial point towards the PCS periphery, the tracks are arranged at an angle to the PCS. Each of the plurality of first radially extending elements is connected at its inner and outer ends to enable formation of winding contours and other chain structures. When elements are connected to such circuits, external ends of elements are connected by means of interconnections of external circuits, and internal ends of elements are connected by means of interconnections of internal circuits.

EFFECT: technical result is reduction of effective resistance in windings and, consequently, reduction of associated losses in order to achieve specified current density in fragments of rotating energy conversion devices.
