Forgive me for my newbie question. I am still trying to learn Arduino with the end goal being motion control such as CNC machines etc. I have some BLDC motors that I bought a while back on ebay and dont have any data other than the motor plates. I havent removed the servo covers to see if I can find any information on the encoders yet so I don't know how much difficulty that will entail. My question to those who have more experience than me is should I even bother with these or just start with a known quantity?
We have even less data on the motors, hint...
Post pictures. That might help.
You ask about the motors and then say you have not opened the servos. What servos? Where do they fit into your questions?
The CNC machines I have seen use stepper motors and threaded rod.
The motors are servodynamics model no. IG23CS-64-IE2000-S. TCS 6.23 lb-in Ics 1.02A, max speed 8000rpm. They are BLDC servo motors and are fitted with an encoder at the end.
Ah. So, not so much an unknown motor.
;D
Well, except for wiring diagrams and other specifics on the motors they are unknown. I can no longer find the datasheets via google so I don't know the encoder wiring or motor wiring.
Well, I'm an idiot. Turns out if you type servo dynamics instead of servodynamics you get the datasheets!
So here is the data on the motors. What do you think? Doable with arduino?
Are you sure its an encoder and not a resolver - some of options use a resolver.
Yes, incremental encoder 2000 lines. I did find some more information when I enquired back in 2011 on another site. Looks like the motors are eight pole with Hall effect commutation, three commutation channels. Looks like I can drive them with a trapezoidal waveform.
If its has hall sensors then its relatively easy - you can commutate from an encoder its absolute, but
incremental isn't helpful for that.
