Experience With 6 Cim Drive train

[Rob Stehlik]

There are some interesting ideas here for dealing with main breaker trips.

I think the best solution is to gear more conservatively and enjoy the extra acceleration. For short distances, slower is faster. The last two years we have run a 6 CIM single speed drive geared for around 11-12 fps, and have never tripped the main breaker. We have used a spreadsheet to help optimize our gear ratio, and this speed seems to be a sweet spot for single speed drives. It provides great acceleration, and the current demands are low enough not to trip the main breaker. Most of the teams I have talked to about breaker problems were geared higher than 12 fps.
