Help diagnosing a broken Hardinge HLV power feed motor.

You could probably find a place on the machine to mount them- they shouldn't generate much heat
They can easily tolerate 50-60 degrees C forever
The specs are fine and likely overkill but they won't fail again

@markba633csi your diagnosis was correct: the controller was behaving correctly when tested with the multi-meter, but was failing when under real (motor) load. I replaced the old rectifiers as you suggested, and everything works like a charm, thanks !

@f350ca thanks for providing the diagram, it was really helpful.

I like a happy ending!
One of those situations where aftermarket really is better than stock
