Homebrewed CNC, Looking for Servo Drivers
Homebrewed CNC, Looking for Servo Drivers
(OP)
Hi All,
I am attempting to help a colleague who is constructing a homebrewed CNC router table. He is a very capable mechanical engineer with limited electrical/controls engineering knowledge.
He has used servo motors which were lifted from a SMD comnponent placing machine that had decommissioned itself by a combination of age and quake damage. The motors are in excellent condition, but the servo drives were destroyed beyond repair.
The motors that he has are Sanyo Denkai brand, and I have had very limited success in finding a datasheet for them. They appear to be 3-phase motors with encoders fitted.
What I can find on Google is very limited, they are 200-240VAC 3-phase motors, probably around the 250W mark. I suspect that this is because the motors are a bit old.
I think that my chances of being able to sort out a suitable drive for these motors is going to be much improved if I can get a datasheet for them, and even then we may be out of luck.
I wondered if there was anyone on the forum who may have access to a set of old Sanyo Denkai catalogues and be able to help me out?
The motors have the part code 65BM007FXEOV.
Cheers,
Mark aka Paulus the Woodgnome

Unless the guy is going into repetitive mass production or will do things like engraving that leave the machine running pattern all night over and over just use DC BRUSHED servos and the outstanding Gecko Drives: http://www.geckodrive.com/geckodrive-brush-dc-drives.html
My router will move at 3ips whilst shoving around a large Porter-Cable router using only small Red-Bull can sized motors driven by older Gecko drives.
I predict a lot of work finding a solution for driving your motors. Yaskawa Signam II series drives possibly, hoping the motors come with agreeable encoders.

I have had to replace sanyo danky motors in the past so have a bit of info on them. I do not know if I have info on THIS particular motor, but if so, I would be happy to send it to you. Problem is, not going into my across town office (where that data is) very often, I will not remember to look when I DO go. So if you want to email me (see my sig block below to find) I will keep your email in my inbox and so be pretty sure to look when I get there.
You know they still have a european (aka english) website:
http://www.sanyodenki.eu/-AC-SERVO-SYSTEM-P-.html
maybe they would send to you if you ask?

found enough info to get you started on picking a drive for it:
