8-11-2012I'm having an issue with my Harrison M300 I was wondering if anyone can narrow it down for me or has had a similar occurance The motor overload relay trips after a minute or so of running with no spindle load I figure that it is because I'm using a static phase converter but I'm not so

11 05 2020I'll attach pics of the mill motor plug it came with It is possible that it was tripping immediately and staying open and therefore you would not have seen any issue (read post #26 for a full review of the wiring options) Last edited May 16 2020 Reactions zdiaz925 Z

corresponding motor limit (the red or blue lines) the motor is at risk of tripping due to high current depending on the conditions Safe operating of a mill and motor means that the process lines should appear below the red and blue lines across the whole range of speeds that are of interest In this example (13% vol ball load and 25% vol filling) the operator can safely operate across the

02 02 2010Dear Skogsgurra thanks for your reply and interest in an effort to solve my problem As we dont have any current recorder in my system so to provide a precise current profile is difficult but I have some details of actual tripping current and the last two tripping values are 4031 and 4068 amperes as now the the mill has gone into some preventive maintenance so I cant give some more recent

05 05 2008The motor does not seem to be laboring or running excessively hot but the amperages add up to 40 amps which is (almost)twice it's name plate amperage and that seems peculiar that it is only tripping out intermittently and not tripping out almost instantly the question is does this mean that with a nameplate amperage of 21 6 amps should it only have 7 2 amps per leg? of course this is the
