Tiny 12v motor burns out a transformer. Why?
I connected a tiny little motor (12 volts, 60 milliamps) to a 12 volt, 1000 milliamp wall wart transformer. The motor turned (no load), but when I disconnected it after not more than 10 seconds, I noticed a burnt smell and the transformer no longer has any output. What happened? Bad luck, or is there something about a motor's inductive load that would be incompatible with that kind of transformer?
