Easyservo is motor and driver
Nema 23 282oz $220 each
Nema 34 1133oz80v $280 each
Nema 34 1133oz 110/220v $350 don't need power supply
And those are holding torque
these prices are only if having XZero machine

Sir, please educate me on the subject of your motors? They in deed look like a fine setup. Can you tell me, when setting up Mach 3 for these motors how many steps per rev. do you use. If I understand correctly the pulse count is 1000. So it would be 1000 X your pitch?
Jim.
So these can be used WITH the Leadshine drives OR with a Gecko 540 with the SAME results?
And what is holding torque vs continuous torque vs maximum torque. Why do you imply holding torque to be more important than the other specs?

George,
You know I did ask you some questions about your knowledge on clearpath but, as usual, you skip right past those and go straight to the leadshine. So, I'll shift gears and move on to what you do seem to want to talk about, leadshine.
I took a look at the link you provided, again, and here's what I found. First, the motors are 3 phase steppers. It's right on the pages linked directly to the page you provided.
http://www.leadshine.com/productdet...easy-servo-motors&series=ES-M&model=ES-M32320
Now, I'd like to know what items you offer to work with the individual leadshine drives to facilitate all the other things I need on my CNC routers. I need access to many more inputs and outputs for all the spindles controls and tool change inputs and outputs I use. I also need inputs for home switches and outputs for controlling vacuum hold down and dust collection. What are your solutions for those items? Are they 5v TTL based systems or are they external 24v systems? Are they single ended or differential? Also, I'd like to know what MC2 asked about. All the motors I saw were equipped with 1000 count encoders.
You know, the funny thing is that I've been curious of the leadshine systems. Jake and I have talked about them on more than one occasion. I would love to have a good objective opinion on them from someone with experience with them. But you refuse to answer simple questions that, based on your claims of expertise, you should be able to answer very easily. Maybe you do know something about leadshine and you will answer some of these questions about them. Unlike what happened when I asked questions about clearpath.
Royce
I will if you'll use your arms to pull your head out of your own ass. You should actually try to LEARN something about Clearpath SDSK motors before dismissing them with your wildly incorrect and uninformed statements.
Your attitude makes you a very poor representative for Leadshine motors - not only would I never consider using them I will be sure to strongly recommend that my clients avoid them at all costs.

Is there any chance we can try and keep this civil??? I genuinely like everyone in this thread, but the ego's being demonstrated are destroying what could be a very helpful discussion.
I don't need to learn anymore about name calling or the like. Anyone capable of speech can do it. I was 4'8" and 75lbs when entering high school. Heard it all.
What I WOULD be grateful for is some explanation, in layman's terms, regarding the alleged accolades of the equipment being touted here. I doubt I'm the only one...
I'm a fisherman by trade and can park a 100 ton boat without any problems(normally) and I understand how easy this is for some to understand. Catching fish is very simple for me, but I watch most people get confused every day...

George if your going to sell that crap than atleast clarify that "phase" in this case actually represents "poles" as in 3 pole 1.2 degree vs. 2 pole 1.8 degree
For the record I have 5 of the 2 nm 1.2 degree motors and drives.
I also have clear paths. The packaging of the clear path appears to cost more to produce than the entire leadshine setup.

I understand where you're coming from, but the only way any discussion can become very helpful is for a legitimate back and forth to occur about the topics at hand. Unfortunately you just can't make someone do that. I've tried to encourage, and even dig some information out of the discussion only to find side stepping and diversions.
I would really like to know why George says the things he does, but I can only ask. If he's not willing to participate, then there's nothing I can do.
The funny thing is that I haven't said one bad thing about leadshine because I don't really know very much about them. Most of what I've done is ask George where his opinions about the clearpath have come from because he seems to be misinformed. His statements lead me to believe that he's not aware of the clearpath motors that we are talking about, but I can't get him to even go back and look for himself.
Royce
I was referring to Jake, Thomas, and George; all of whom I respect. You've been very diplomatic Royce.
I'd like thorough explanations from George as well. I need thorough because I lack the understanding that the 4 or 5 main contributors to this thread have.
Since Jake owns both, and I've only seen the Clearpath(which I was impressed by), I'd like to hear more about his thoughts on the two motors.
I'd also like to know the importance of holding torque vs constant torque. It seems that they would be the same.
On another note. I'm going to drive some smoked yellowfin(Ahi) tuna to Vegas today and thought I'd bring some down to the OB booth. I'll also bring paper towels as it is a bit oily. If anyone else would like some, and you are in Vegas, let me know.... I only have a couple pieces left...

Well, priorities first, the tuna sounds great! I'm looking forward to it.
Now, as to the information, I'd be happy to help with what I can. On torque, servos and steppers are rated differently. Steppers use holding torque, as they are really a holding motor. Servos are rated more by constant torque, and it's the max torque they can provide continuously. Servos usually also have a max torque which is what they can hit for short periods of time.
Stepper motor torque drops off dramatically as they begin to turn, so the torque numbers are always much higher than in application. I am replacing the gecko 280 ounce steppers with the clearpath 492 ounce peak motors. They are around 100 ounce constant. It looks to be a good fit. There are a couple that are stronger, still in NEMA 23, but I don't think they will be necessary. Here's a link to the ones I've ordered.

Randy, its kinda simple but complicated.
for comparison:
stepper motors have maximum torque at standstill / very slow speeds making them perfect for a machine like the Xzero pool cues. Perfect for this particular machine because it has a fast pitch screw with no belt gear reduction. The faster a stepper spins the less torque it has. This is good for the xzero because the stepper never has to spin that fast. Now theoretically once at speed much less torque is required if the machine is designed well. I think George is running the machine on the ragged edge of inertial mis match failure but thats just my opinion of course. Maybe he just has acceleration set low
Servo motors are opposite, they have little torque at standstill / low rpm and usually need gear reduction on machines with hardware such as the xzero. Basically if you were to put a 3 to 1 pulley drive on the screw, the servo would have to spin faster and thus put it in a more optimal torque range due to being at a higher rpm. They are typically more accurate from a resolution standpoint.
The clearpath is actually a servo motor that shares the good qualities of both. It has higher torque at low speeds and also has encoder to maintain position. The quality of the unit is far and away light years ahead of any brand mentioned in this thread including yaskawa and mitsubishi. Also, as another smart guy pointed out, the encoder and drive are contained in the unit, so there is no positioning cable to get damaged or suffer from RF trash. The price is also very delighting.
Also, Easy servos are not servos.....there stepper motors with encoders

I can insure you they are far from crap .Leadshine manufacturer their own products. Leadshine USA is bring them to an affordable price in North America.
Oriental motors sells lots of 5 phase motors.

What about the rest of my questions George?
I'm giving you the opportunity to join in with us and provide some positive feedback for the readers here. Please don't leave me hanging.
Come on and read the post I made and answer some of the questions for the readers here.
I'm working our booth at the APA tournament in las vegas and I'm still responding. Please join us.

I have been down this road already and not doing it again.
I will not give opinion on Clearpath, Only thing is if jitter control is on it will round out corners and make circles not round with some controllers.
For people that said followed me since i started would know the month and months and months and months and months and months and months even a lot more months that XZero name and machines got totally FKN bashed daily till i was at the point of days from going under . From people that didn't even have one of my machines. All over a servo motor set up. I can see its going in same direction again
Not till one person almost lost a hand. Another person had gantry take off full blast with no one even running it and just by a hair missed at customer at almost 1500 ipm with 250 pound gantry.
Another person changing bit and machine took off and almost crushed him.
Then people new it wasn't machine no more and was motor kits.
So , now i see people calling leadshine crap, ? for what.
I have 100s and 100s of customer saying the are perfect.
Here on this forum alone is close to 20 people that i have sold leadshine to.
I kinda see where this is going already , hinds of crappy products a little hind of ragged edge machine failure , so i know the bashing will soon start and getting will more geared to machine very fast .
So that being said, It better to listen to the godz of the forum and bow out

Here is small 282oz stepper with MX3660 , if you look on sides and flatness on bottom you will see how good just the steppers are

Thank you Royce and Jake for explaining the torque to me in a way I understand. It seems George is convinced that this road is paved with those dedicated, ultimately, to bashing his machines. I don't think this is the case, but I'll respect his decision to bow out. I like him and his machines. Hopefully I'll get mine running within the next few months. He's always been easy to reach and helpful when needed.
Royce, we are still an hour or so out, so fish tomorrow.

You remember somebody saying something bout humility?
Things started to go south when YOU began negativity and discounting others ideas and suggestions because YOU know better. Things haven't changed much from those months and months you speak of. Sometimes it's good to be wrong.
Keep an open mind......I'll leave you alone now.
I happen to still like the XZero machine and still advocate for it.

I have to say that I really don't understand.
I haven't asked you a single thing about clearpath. I have asked you for 2 things in these recent posts:
I asked about whether or not you were aware of the SD clearpath motors. Which is about you, not clearpath.
And I asked you to tell me about leadshine's systems. I even begged you for some information and you still come back as though I'm bashing you and leadshine.
I'm sorry that, for whatever reason, you are so insistent that I mean you harm when I really don't.
I really have no idea about whatever issues you had with servos in the past. I don't know about runaway machines either. If you had replied with real world experience about those issues and what caused them I'm sure this thread would have gone down a completely different path. Instead, you chose to play defense when there isn't anyone on offense!
I'm sorry if I've offended you. I certainly never felt as though I was on offense, so offending you never crossed my mind. I just wanted to have a conversation.
