We broke down the motor and inverter tonight. We located the component in the inverter that melted down, But could not figure out why it melted. Upon disassembly of the motor, it was apparent. One of the induction rods in the rotor overheated and burned a pinhole in the stater. The stater and the rotor clear each other by hundreds of thousands of an inch at 18,000 RPM. Once the hole formed and some debris got in that gap, the meltdown was inevitable. I believe the fuses we were running were too big, which allowed everything to overheat before the fuse saved it. There is no way to know the limits until you press them. Now we know.“Once all the safety updates are in place we expect to drop a new world record early November 2021”Roughing in the battery/ engine bulkheads. 1/4″ cored carbon fiber lined with 1/16″ Garolite on the inside.Peter Shadowen making adjustments to the inverter.
We made a full containment, super deep, lay down seat, since we could find none readily made on the market.After testing we installed a fin upstream of the prop to help the “paddling wheeling” of the surfacing prop.An AEM CD5 monitors the vitals, an IPad takes care of a myraid of other housekeeping chores, and Calgo steering keeps her pointed straight.A little bling.She floats well.Installing the steering cable bulkhead, Bert Mensah and Tom Kaufman.It’s go time targeting wet testing Sep 30, 2021A little more bling.
