Hi!

TLDR: Is there a direction a SmartDrive rotor should turn? Does it matter?

Longer version:

Ok so I have an off-grid solar setup which is great between March and November but the other 3 months of the year are pretty cloudy/rainy in the Pacific Northwest and with the short days we need to top-up with a generator.

I do have a seasonal stream that gives me 5-10L/s @ 15m head so I am *attempting* to cobble together a basic hydro rig to see if I can actually produce anything useable.

Through the amazing resources available on thebackshed and others I have gathered the needed parts and bobbles and am rewiring the SmartDrive stator to suit my site and system (3P4S with provisions for either start or delta). I bought what looks like a pretty decent pelton wheel on eBay and have 100m of 75mm hose to go from the source (a culvert, really...) to my turbine.

Next I'll assemble the turbine & rotor together reusing the shaft of the washing mashine to attach the pelton to. Does it make a difference which direction the rotor turns? IE I can attach the pelton so the rotor turns clockwise or reverse - does it matter? I can't seem to see anybody specifying this in their videos so I'm guessing either works but not sure...

I guess my question illustrates my lack of undestanding of the fundamentals of permanent magnet motors but here we are lol.
