Actually, unloaded locos get up to speed surprisingly quickly ;-), especially when you go WOT on a 3000 odd hp diesel!

My estate will be getting a remap at some point which should take it straight up to around 120. Add an intercooler and sort the pump and it's 150+. I fitted a towbar and towed a caravan chassis behind it, barely noticed the extra weight. Pug rate the estate to tow 1200kg braked!

That doesn't count

as it's only turning a Generator, the batteries power AC motors - which means maximum torque from 0 speed.

That system in a car would make it rapid off the mark as well.

I've always wanted an estate!

Like all electric cars ???

Going to be getting a skoda octavia vrs estate in a few months. Means I can carry myself and all the massive amount of kit I have around as I'll be moving alot, and can tow the saxo and so have that off the road just as a toy. Think they look good and aggressive, comfy things and good value for cash. What a boring cunt I'm becoming..

Chr15 · 4th May 2014, 20:48

An aggressive VAG. Really?

No.

engine > generator > batteries > motor > wheels. Is what I mean.

All electric cars are just battery > motor > wheels

Hybrids are Engine > gearbox > Wheels & motor assist

I was on about torque, I may make electric cars, maybe, a bit, ish.

the leaf is 100% electric and has a gearbox btw

That's cos the leaf has so little power, I'd imagine. Unless you're being picky, in which case a 2:1 reduction gear is technically a gearbox.

I don't get why the can't just make them direct drive, it's less loss.

I was meaning a setup like a train in a car.

without the box they actually rip themselves apart, they tried that

Dat torque doe

Shit aye, just looked up the spec. an 80KW motor hahahaha xD

Single speed reduction gear of almost 8:1

It's a Volvo engine which the focus uses, so all good!

Not normally any batteries involved in locos. Some locos are D.C. traction motors as well. Hi/lo gearing is achieved by switching the motors from series to parallel wiring, and/or switching the two motor windings from series to parallel (or field weakening), although this does depend on the motor type.

Main reason that electric cars aren't normally direct drive is the motor flexibility required. In general you can build an electric motor to make loads of torque, or loads of revs, but it's very difficult (expensive) to do both. Also, a motor that could shift a fully loaded car from standstill as direct drive would be very heavy and suck down a shed load of amps on startup.

Much bigger motors out there. ;-). The fact that most motors can absorb up to 5x their rated power for short periods and it makes you realise the potential for electric drive trains.
