DIY Nema23 Motor Mounts

[Lee Roberts]

I have just found some more pic’s of my motor mount fixed to my machine, (Rockcliff) here you can see how I went about fixing them to the machine.



and fixed to the machine:





Ok the pic below shows the motor and mount fixed to the machine, my lead screw isn’t in its correct position and that’s why it’s not lining up with the motor shaft (I was fiddling about, just wanted to test how things would look).



You may also notice that the motor isn’t fixed on with anything, i.e. I haven’t put any nuts on. This isn't permanent obviously and of course I will fix the motor with nuts and washers, I was just test fitting everything.

Also shows you how strong the motor mount is, it’s not even flexing with the weight of the motor!

The pic below shows the lead screw in the correct position and nicely lined up with the motor shaft awaiting a coupler!



GO ON HAVE AGO!

Been playing around with Google sketchup and trying to decide whats the best design for a motor mount that:

• Supports a NEMA23 motor
• uses a 8 x 22 x 7 ballrace and two 8 x 16 x 5 thrust races (these go either side of the ballrace mount
• a 6.35mm - 8mm motor coupler (the ones Lee sold me, whatever they are)
• 10x2 or 12x3 leadscrew turned down to 8mm for 50mm and threaded M8 for the last 25mm of that.

The second is slightly harder to make but is more compact and rigid I think...
