Is this a decent controller for the Warp 9?

From a quick look I'd say no. It looks too much like a Kelly. And 4 quadrant on a series motor? Don't think so.

Beware,

Thanks. Says it has capabilities for regenerating braking. I thought only AC motors were capable of such.

A DC motor can run as a generator, but needs separate control of the field winding to do it properly, which means a separately excited (SepEx) motor instead of the very common series-wound motor.

I don't know why anyone would think this is German. A quick Google image search finds several web pages showing the same image, which appears to be this:
Keya MMT-4Q-FB from Jinan Keya Electronic Co., Ltd

Series motors can regen too.


Regenerative Braking has been around a very long time.





But the controller looks like its VERY overpriced , I wouldn't pay more than $300 for it.
