#140275 - brushless exciters?? Responding to: ???'s previous message |
You could try a search on this. I did a quick search and did not find one that delivered under 50A though and I suspect that may be a bit too big for this app. I did see some brushless motors that may be the right size, maybe you find one that could be run backwards as a generator. My last job delt with using brushless exciters for power delivery and an optical ring for data collection from the rotating side. They ultimately gave the optical strategy up for a wireless ethernet solution which I understand worked out well, though I left before I saw the results and don't know how easy it was to implement.
Good luck, sounds like fun. Andy |

| nah. | 01/01/70 00:00 | |
| it all depends on the dimensions... | 01/01/70 00:00 | |
