96v Motors - More Advice Needed

This is for the following EV boat. See discussion for more information.

96v Solar Cabin Cruiser Project - Full...

Starting this thread to document the full Solar Boat Conversion Project. Always looking for good advice. The Concept 1) I will eventually be converting a nice 40 Cat or displacement Hull to Electric. Needed a project boat to experiment on first. 2) I found this 23 foot boat for $1800 +...

Scenario

On perfectly Flat water with no wind, I will only need about 10kW to keep Hull Speed.

• But.. when is it ever perfectly flat with no wind.
• I will have a 85kWh Battery that can do 500amps at less than 1C.
• Most trips will be under 20 miles so not afraid to just chow thru battery for small speed gains
• Want the ability to maintain hull speed even in wind / chop
• This is a test system for a much larger boat
• I can re-gear to get 1900 RPM (Belt system)

Due to the above, I am looking for the most powerful 96v motor/controller that can run continuously at 250 amps. 96v * 250amps = 24Kw motor. something that is not pushing its self at 250amps.

Preliminary research is leading me to these options. But I may be missing a lot. Any feed back on AC induction vs Water cooled Permeant Magnet?

• What runs better at sustained load
• what are more robust

ME1616
Motors DC and PMAC :: ME1616 - would be coupled with a large Curtis controller.

AC-50 / AC-51 AC Induction Motor Drive
AC-50 72-108 Volt 650 Amp Kit
HPEVS AC50, complete motor conversion kit. Includes motor, controller, contactor, display, wiring harness, choice of throttle, and custom programming.
