Re: [PSUBS-MAILIST] oil compensation - ADS NewtSuit/HardSuit Applications
Carsten,
Hi, I'm curious as to if you investigated why the motors sometimes did not start? Just too high viscosity? Or maybe
electrical resistance effects?
FWIW: I've mostly seen mineral oil used for pressure compensation, but most of my experience is not in applications with
fast rotating parts.
