At the beginning of video you’ll see motors shaking synchronized (both follow sin(t)) and after that, one motor follows sin(t) and the second cos(t) function.

I’ll think of better demos later :)

Hi Everybody!

Honestly I didn’t see any synchronized motion. I mean any usable in the industry. Please, turn the both drives together with the same positon setpoint at 5000+ rpm. Put a stroboscope triggered by the index pulse of one of the encoders. Voiles – it would show if the motion is really synchronized. I’m pretty seduced to see / provide such an experiment – if I could have 2 drives of course.

The name very originally was VSD-XR but was renamed to Argon as it is so much different from any VSD drive.

Argon already has the most powerful high freq capable motor power stage module available from Fairchild semiconductor.

and I not think the old electronic control can get out as current

you think to design a version of “X” for argon as the VSD-E
which is available in VSD-XE?
to deliver more current

The DC motor specs looks good, however that peak current is very high and Argon can’t output that much (~20A max). However, this affects only to available short term peak torque which may not be needed anyway. More important 12.8A continuous can be fulfilled 100%.

I have a DC motor without brake control
I do not know if I could dynamicly also important to
their characteristic :
max voltage 200V
nominal current 12.8A
peak current 125A
permanent magnet

However I had no drive for them and didn’t feel like using some random stuff from ebay, so I started designing a drive. The rest is history :)

response speed of the motors is incredible is exelent for CNC machine tools

what type of engine for this test ?
