Abstract

This article suggests that capacitance between the horizontal and vertical coils in stator yokes can be reduced by winding a buffer layer between the two coils within the bobbin slots. Referring to the drawing, a lacing or strand layer of nylon or similar material can be wound on top of the first copper coil of the yoke using the same winding technology and winder as is used for deposition of the wire in the first copper coil. The thickness of the buffer layer can be varied to match application needs. The lacing is distributed in the same pattern used for making the first coil to assure buffer coverage at the top and bottom of the bobbin as well as in the bobbin slots.
