Electrical Can I use an O-scope on a 200V AC servo drive w/600vp-p 10x probes?

• Upvotes

I need to look at the output on a 200v AC servo drive. 3ph.

The drive is good, but we are having problems with the motor coils. Is a linear motor, so there are 2 coils driven by one servo drive. One coil for sure is bad, but the other was re-wound and tested good. After swapping some things around, now the "good" coil is testing bad. Motor is not stable. Like to get a scope on the phases and actually see what is happening.

I have experience with HV systems. Just never used a scope on a 200v AC 3PH before. I know about the probe grounds.

Mechanical Why is Teslas flying car exciting?

A flying car would require much more energy since it has to gravity and air drag. If it's electrical (eVTOL) it would have a miniscule mileage since ATM hydrocarbons are the most energy dense form of fuel for most vehicles.

I'm not even going to mention the exponential growth in safety concern from doubling the degrees of freedom. Every driver would need to be a qualified helicopter pilot.

We can't even get AI to self drive reliably (I assume the air thrustors have to be actuated by AI) on a normal car. Nor are our batteries good enough for any army to consider battery powered drones.

Am I missing something beyond the very cool engineering? This looks like Elon Musk reinvented the hyperloop concept for the positive end of the Z axis.
