Problem with motors is they tend to be All On instead of throttled even when voltage or amperage is slowly applied. Seen a good many Locos lightly throttle up the Prime Mover and get drive wheel slip/spin almost instantly.
And if you remember my posts earlier, electric motors in my application will have tons more power. I would bet a 200 HP motor would pull the same or better than a 400 diesel.
neat cars like this 914.
Manual transmission drive line is 98% efficient.
Alternator with wheel motors is 93% efficient.
These figures where taught to me in night school by an engineer well versed in the various drive systems. It's not my job to convince you otherwise.Been meaning to comment on this as it's misleading or incorrectly compared. Trying to get more context.
Engine power to the wheels in a truck is probably less than 85% efficient.
Is the wheel motor being 93% efficient power at the wheel because that is awesome or is that just the efficiency of the motor?
Irc regular electric motors are 80-96% efficient, not sure how efficient a Generator is, but it would definitely have to be bigger than the motor
I try to help, and this is what I get ?Ever heard of junk in, junk out?

Buh Buy.If this is your help, don't bother.
Going to Catenary systems as the Milwaukee Road once used would be simplest, Engines are already 600vAC so a line transformer system to that for distance hauls would be a fairly rapid swap where Diesels can still be used or converted to a Hybrid as some East Coast engines already are.
