Let me rephrase that:
What kind of idiot would design a people mover that would go 3x faster than needed suddenly without warning in the first place?
I guess what I'm after is, did it suddenly go from say 120V to 277V (impossible, I know) and briefly speed up before burning the motor up, or is some controller inadvertantly design to allow just such an occurance...
I'm just having a hard time imagining a 60 Hz system suddenly becoming a 180Hz system, and on just one machine, I'm obviously missing something. Can motor windings fail in such a way to cause this type of symptom?
Am I being stupid? Am I the only one that sees the absurdity here?
I'll shut up now...
