Will, and the rest of you fascinated by power distribution,
A big synchronous motor allows its power factor to be changed by
changing the field current for a given load. The motor can be
adjusted to look like a resistive load instead of inductive, or
even capacitive to correct plant power factor.
Bill,
I never did set back and think why they used them, but that would make
sense. The new plant engineer they hired, during my time there, talked them
into installing a new power house (air compressor system) in the paint
department. However, he had ordered screw compressors, running on 460 V,
