Cheap PMDC servo controller

(1/1)

ezalys:
Does anyone have a favorite PMDC servo controller with 24V/3A capability? There's the geckodrive G320X, some older maxon controllers, the granite ioni. Anyone have any preferences? If I could find something around 50-70 USD or so I'd be pretty happy.

Benta:
Do you need just speed control or also position control?

Doctorandus_P:
Maybe one of those motors with built in controllers are interesting for you.
Prices for the combo start at around EUR 100.

I think JMC started with those, but I think I've seen other brands on 'Ali too.
Some of them are closed loop steppers, so read the specs carefully.

H.O:
Since you mention G320X, is step/direction what you want or what type of control interface do you prefer?
And since you mention the Ioni I take it you're with boards without enclosure?

Polulo offers a series of drives/controllers but none of them seems to offer step/direction:

I've worked with both the Maxon EPOS and ESCON series as well as with Granite Devices Ioni and they are all excellent products but they won't hit the $75 mark.

The DG4S-08020 from CNC Drive cost €99, I have not used it but have used an older drive of theirs.
