Half‑wave inductive‑stress motor experiment: unexpected voltage rise behavior
I’ve been working on a side project involving half‑wave inductive‑stress applied to a DC motor, and I wanted to share some of the results because the behavior is… unusual but repeatable.
Under load, the motor output voltage climbs all the way up to 282 V, even while the input voltage is falling.
This voltage‑rise happens consistently across multiple test points.
For comparison, I ran the exact same half‑wave stress on:
- AC motors
- Resistive AC loads
- Inductive AC loads
All of them collapse immediately under the same conditions.
Only the DC motor continues to rise.
I’ll upload the full set of photos showing:
- the test setup
- wiring
- measurement points
- oscilloscope captures
- motor behavior under stress
- and the voltage rise sequence
Photos coming right after this post.
For anyone interested in seeing the real‑time behavior, here’s a short reference video (non‑commercial, just documenting the experiment):
More details and breakdown in the comments once I upload the photos.
