Where in the EU or maybe China, Hongkong I can buy DC-drive
Leadshine DCS 303. I know only sources for the DCS810, but this part is much to strong for my motors and more expensive as well.
German google don't find anything, thanks data safety.

How about this

What size and type of motor are you trying to use.?

Unfortunately, this part isn't a DC Motor driver. It only works with BLDC aka AC-Motors.
I have Yaskawa-Minertia Motors J03M-GG12 and UGJMEE-02XIB12 each with a 500PPR
single ended and differential encoder. It have no Index but that isn't a big problem. A simple
holescreen somewhere and a potosensor should be enough.

Ok well maybe this a language problem because what you say is wrong.? The Drives I showed are BLDC drives. Meaning they work with (B)rush (L)ess (D)irect (C)urrent motors not AC motors.

I think you mean you need AC Servo drive not DC.

No, not language problem, I have indeed brushed DC-motors with Encoder. Maybe, if i add a 3~ rectifier and a Capictor behind, I can make real DC with it, but why, if I can buy real DC-Drives.
But I fear, that don't works, because the tension don't run from nearly 0V to the Sourcevalue.

BLDC is imo only another word for a 3~ AC Motor. Maybe it works with PWM instead of Sinus and have Permanent magnets in it instead a shortcircuit rotor. But the principle is the same.

Ah you didn't say Brushed DC motors that's different story.! With you mentioning ACS810 being ok but out of price range then I assumed BLDC because believe those drives only support BLDC not Brushed motors. May be wrong on that but they do support BrushLess DC motors.

Also Don't know how you come up with BLDC drives being AC thou try connecting AC servo to one and See how well it runs.!!
