Have you ecer experienced a motor do this?

[IRBH]

It wasn't wind milling backwards at any time. It would not operate with a load on it CW or CCW without tripping the 'internal" overload. A weak/bad or improperly overload when the 12 year old child labor kids made it. Thanks for you all's insight.

So the op still maintains that the motor overload should NOT have tripped after running some time at 250% overload?

I've heard of Service factor, but not this much.
