No, pick any two. If the 3 phase motor on your tool runs in reverse, swap any two wires going to the motor. ------------&#92;--------------------- &#92; 220 3 ph

Rich, I didn't ask the initial question but would like to thank you for the dirt simple answer. Does it matter which of the motor windings the 240 and 3 phase stuff is connected to? Drew -- Drew

Tom, I did remove the clip first by using one of those "dental pick" type tools to lift up on the internal tabs until I could get underneath it with a pair of long needle nose pliers. On my motors

Hi John, Just tried it ... No DNS problems and the server responded fast. Suspect a transient DNS problem somewhere, now resolved. George John Ross wrote: -- ------------------------------- George

Joe, It is quite simple. Connect your 240VAC across two of the motor windings. Connect the 3ph load circuit across those two windings and the third leg. With the 3ph load switched off and the 240 1ph

I'm getting a "cannot find server" error for the Servo Dynamics web page. Has anyone else had problems or is it just me. John Ross I-Link Worldwide From: "Matt Shaver"

Thanks James, I knew about US Digital. I was hoping this was something else, as I was looking for a little higher resolution linear encoders. (cheap) Thanks Mike james owens wrote:

Can someone tell me exactly how to make a "pull start" phase converter from a 3 phase motor? I am going to try it this weekend and need some tips. I have a Baldor 3/4 3Ph that I want to drive a

<A href="http://web.wt.net/~hmsc/phconv/phconv.htm">Phase Converters</A> Sorry! I did summin wrong! HERE it is!

For you folks pondering 3-phase converters, I give you here a link to an article by a machinist/electrical-engineer-wizard who is a member of and past-president of our local Home Metal[workers']

In response to the person looking for cheap linear encoders, US digital sells linear strip at $2/inch ($14 minimum) which works with $30 or so HP reader heads. The resolution is 360 cycles per

first you have to have a capacitor phase convertor---you hook it up and use the motor windings to smooth out the generated phase-----thats the way ive done it--good luck--if you find another way

Tom - What was the resolution of your linear encoders and where did you buy them? thanks Mike "SMITH, THOMAS B. (JSC-DX)" wrote:

Terry, The pictures are very useful, thanks! And don't think you are beating this to death. All this discussion has saved me (and others, I'm sure) a fair amount of cash. I just finished

I've just taken a major step towards a real servo CNC system. I scored an industrial robot at a price I couldn't pass up (free). There is no info on the servo motors that I can see, but the

Where is a cheap source for good linear encoders? I'd like to have resolution better than 10000 / inch. Elliot Burke

Hello Terry, Welcome to the ranks of a participating member of this list!! I think you will find a tremendous amount of help and support here and will never find that the list is short of opinions

The nice thing about starting the CAM route by setting up manual power feed first, is that you can do only one axis at a time. The drivers require a step signal, and a direction signal to operate

Thanks for the notes. I guess the 'hand hold' test is not a good measure of motor heat. Must be why measuring instruments are used :-) My driver module has a pin that controls current and a table of
