Hi,
where did you buy your Panasonic servo motors and drives.

Hi,

Who are you asking?

[Muzzer]

Not sure who used the Panasonic servos but in my case, I used DMM Tech servos for X and Y, as mentioned on the controller thread http://www.mycncuk.com/threads/13520...the-controller I was living in Vancouver at the time, so I drove over to the DMM Tech building and picked them up in person.

DMM Tech seem to me to be somewhere between hobby and industrial. No disrespect to them intended but they really aren't in the same league as Panasonic, Yaskawa etc but there again, they don't claim to be. And the pricing is an order of magnitude less. As I've spent many years myself developing similar products, I took one of mine apart and it wouldn't get through a proper design validation test - but it works fine in my workshop environment for my purposes so I'm happy.

There seems to be a Korean supplier on ebay who recycles servos, motors etc that have presumably been swapped out (preventative maintenance) after reaching their service lifetime on mainstream industrial machine tools. That seems like a good option for getting hold of good quality ("proper") gear at sensible prices. Can't recall the name, mind. Perhaps somebody here knows.

I've been using Panasonic. I tend to use a guy on ebay called GPWizard (or similar). his stock varies but can sometimes source what I need.

People's experience of DMM seems very much hit and miss. Some love them, some hate them. The Panasonics cost more but they are great bits of kit. I wish I knew how to use them better but it is what it is.

My next option/ avenue would be to look at the 'common' cheap servos from China. It might be a 'get what you pay for' but for me something like DMM, with the mixed feedback) is simply too expensive. Id either go Panasonic and know I get what I pay for, or go cheap Chinese (which many are using but I have no first hand experience yet).

Hi,

I was in a thread a few weeks ago and it was pointed out to me how much Yaskawa had come down in price. You can get 750W set for around £450-500 on Ebay just search Yaskawa Sigma. I'd use these over most other makes and DMM or Delta etc don't compare to Yaskawa, esp when it comes to tuning and software. They basically tune them selfs on the fly. Go to youtube and check out the Vides and the tuning software.

A good shout. The 'premium' brands are worth it if you can afford their kit.

You did a very positive youtube video on the BST servos/drives, how did they perform on the machine? The 750w Yaskawa drives at £500 is that second hand.

If you are talking about the 1.8Kw then yes they worked fine, they actually ended up on a Lathe. Well 2 did the third I still have waiting for a project.
I've also got some 600W 60mm here that I may do a video on as well.

The Yaskawa where new here a link for one I just did a quick search on Ebay, if you look around you may find them cheaper. They are fluctuating in price I've noticed, obviously because of the state of the markets.!

Colin if you use servos what controller are you going to use and how do you plan to run them.? Analog or Step/Dir.
