Question about earth/ground wires

Not sure if this is the proper forum section for such question

I placed order for many items, like VFD, servo motors/drivers, line filters , mesa 7i76e, closed loop steppers and drivers.

My question:

I do not have ground wires in my workshop/garage/home 

I know the earth wire is a safety thing, but does it affects the functionality of any of the items described above or related to CNC machines that I may need to buy in the future( I suspect the line filters).

If the answer is yes (The grounding will alter the functionality of some devices)

Is there a way that I can build a localised electrical earth sink (maybe a chunck of metal, salt, and water or someting. I have no clue).

Many thanks

Yes, you can add an earth ground.  I'm not competent to provide exact specifications, but what is typically done is to drive an 8' or 10' copper rod in to the ground near the equipment (through a concrete slab) or near the breaker/fuse box and use that as your ground point.  Metallic conduit & ground wires will be connected to the rod through a ground bus bar.

Note that solid copper rods, while better conductors, are extremely expensive.  Copper-coated steel or galvanized steel are about 10x cheaper and are likely sufficient unless you live in an area with very acidic/corrosive soil.

I have seen cold water pipes used as ground rods in older homes, but I wouldn't recommend that unless the price of a proper ground rod is simply prohibitive.  The issue with water pipes is that stray currents can cause galvanic corrosion at pipe joints or pitting.

I have a feeling and I could be wrong that such specs are needed for human safety. Not sure it is for devices proper functionality
