Hitachi MLFC wire
Hitachi MLFC wire
(OP)
I was setting up a chip conveyor speed control and was going to use a current tranbsducer on the spindle drive AC input as my speed reference. As the spindle drew more current (cutting deeper and making more chips) the chip conveyor speed would increase. However I cannot get a current read with an AC current transducer, or my Fluke meter through this MLFC wire. I have not found anything on the wire that indicates it is shielded to prevent emf noise. Does anyone have any experience with this wire and if so, similar conditions?

Should be no problem -- Hitachi's own MLFC brochure (see download) shows it going through conventional CTs. It's not shielded.
Good on ya,

Aside from the possibly magical properties of the MLFC cable, measuring the harmonic-laden input current isn't going to give you a terribly accurate indication of the input power, although there will certainly be a relationship.
