Wired mud motor components, methods of fabricating the same, and downhole motors incorporating the same

A method for manufacturing a system for drilling, the method comprising:

• receiving a drive shaft for transmitting a torque to a downhole tool, the drive shaft having a tubular wall around a hollow central passage for carrying a flow of drilling fluid;
• forming a bore extending from a first end to a second end through the tubular wall of the drive shaft along a longitudinal axis thereof and external to the hollow central passage;
• providing an electrical cable that extends through the bore in the tubular wall of the drive shaft for supplying electrical power to the downhole tool;
• and
• disposing a flow diverter having a body in the tubular wall of the drive shaft between the first end and the second end, the flow diverter including a plurality of apertures longitudinally spaced along a length of the longitudinal axis of the drive shaft and the hollow central passage, wherein the plurality of apertures are configured to divert drilling fluid flow from an upstream annulus section of the system to the hollow central passage.
