Re: What Happens When Metal Gets Into A Jaguar (SMOKE!!!!)

For years First Teams have assumed that metal cuttings have found their way into victors and caused them to short out and fail. Now the same assumption is being attributed to the Jags. I submit that some of the failures have been from metal but, a far larger number of failures are Fet heat related. Our speed controllers are hard switched and subject to avalanche conditions. That combined with the higher switching frequency and switching losses in my opinion are the reason for many of the failures.
