Re: pic: burnt up TETRIX motor
Has anyone experimented with the use of a 10A fuse in place of the 20A "default" fuse? Haven't seen it discussed elsewhere.
As long as the fuse survives the inrush current, it appears that it should hold during a "normal" climb using two motors near the max power operating point, yet still open reasonably quickly once a locked rotor condition occurs. Perhaps this would have prevented the OP's issue altogether - or maybe not.
Our plan was to do this during build season, then revert to the 20A fuse for competition (and even then, replace that fuse every few matches). The worst-case scenario *seems* to be that there might be a lot of nuisance fuse openings, but it would be far less expensive to replace fuses than motors.
