I love the idea of an electric 40. Think of the wildlife you could sneak up on. However, how does the torque work? Is it really
200 ft/lbs at zero rpm? When you are four wheeling in rough places, when a wheel gets tucked over center under a ledge or the font end
is buried nose down in a "V", you can work the clutch or judge by RPM when not to push forward. 200+ ft/lbs through a 30:1 reduction with 35' tires is a lot to consider. I can break an axle or birfield at will with a stock setup but you have pre warning. The motor will bog down or you'll be floating the clutch. You have to make a concerted effort. I'm curious how that will work with the electric motor at full
torque off idle

With your project stage It would be interesting to consider the following. I’m not sure how that would effect the project.
This would be a great approach to open it up to a number of rigs. AA adapter would bolt up to any case and split case compatibility in your design would make it stronger / potential apply to 60 / 70 series as well.

That's where the controller comes in. You have a throttle with the e-motor that can change the frequency of the motor, and how hard it's driven. You can have 100% torque at 0rpm, but you can also have much less.
If the controller is programmed right, it would drive pretty similarly to an automatic transmission truck. Obv no noise, and depending on setup, no shifting, but pretty much the same. The harder you press on the go pedal, the more power you are putting out.
Got it. Maybe they could program in the sound of a kid screaming when you approached that "break a birfield" potential
I love it
This is definitely intriguing , I've been meaning to set aside time to look into the tech. I noticed that Tesla S uses a ~80:1 final reduction.
They have a single trans ratio of 8.28 and an axle rario of 9.73
What is the relationship between gear reduction and heat or battery life? Will the use of the t-case and tranny , given the low range final drive is less than 30:1 , be a benefit or liability when it comes to heat and range? Will a 30:1 be enough? Straight through in hi range
we're talking 4.11 : 1. The Tesla runs 20 times lower gearing....or does that matter

This is very cool. Not sure how I missed it. Sub'd.
I am running a 9" series wound DC motor on 144 volts nominal and 500 amps max in my little conversion that curbs at 2600 pounds.
It is almost all hills here in the Ozarks so I use the fill 500 often.
At 300 miles it takes about 125Kw to recharge. At nine cents a kilowatt times 125 equals $11.25, You mileage may vary.
With the electric Land Cruiser It might take a bit more but with it being AC motors I will bet not much.
How do these electric motors run when submerged?
If you sealed everything up real tight so there would not be any dead fish floating around I think fine.
Submarines use electric drive motors.
Interesting. I was just wondering if anyone had done anything like this earlier today. From what I can figure out after doing some additional online research after reading through the various threads, the cost of the conversion appears to be around $10-$12K (about $6400 for the motors), by the time you add batteries, labor, and other components. Was wondering why you didn't go with the AC 51? Now the question becomes how to add heating and air conditioning? Power steering? Power brakes? Thus part of my overall cost estimate, which might be on the low side. Still beats buying a $50K+ vehicle. Still can't beat a FJ40. DMV lady loved my FJ when I was finally able to register it yesterday. She was funny.
Deal breaker? Not necessarily. I'd be more than willing to convert my 76 to all electric. Good for the environment and my guess is that gasoline and diesel driven vehicles will become severely penalized or outlawed altogether in the future. I'll leave it up to you to define what that future may be.
I was an environmental engineer with the US Forest Service. The stuff I saw would blow your mind.
Will be watching this thread closely to see how it all works out.

This is awesome. Looking forward to the day I can do this on my 80
"gasoline and diesel driven vehicles will become severely penalized or outlawed altogether in the future."
Just read a deal about some states are trying to make up for lost revenue caused by electric cars use by placing a use tax on the electrics that in some instances two times higher or more that the cost of gas powered vehicles.
I have been driving my electric car for over 19 years now and expecting news like this the whole time.
It's now up to 26 states imposing additional fees. This is the result of Big Oil at work in an attempt to kill mass adoption of the EV.
Some states are charging extra for drivers who buy electric vehicles
Colorado and Wyoming charge $50 a year, California an added $100, and Illinois tried to introduce a flat fee of $1,000 for owners of electric vehicles.

Im not sure it is Big Oil persay, especially when so much of our electricity is from Natural Gas and lost in our inefficient grid. States are very sensitive to revenue drops and do try to apply some measure of equity when it comes to sharing the burden. One heavily taxed constituency would be right to gripe about another that is relatively untaxed, especially when it comes to paying for road and bridge repairs. CT is in the same boat as Illinois when it comes to revenue keeping up with spending, and anywhere they can increase revenue under the guise of some fairness, they do. In my state they just did it with grocery stores saying they compete with restaurants. It will generate millions of new revenueIt's now up to 26 states imposing additional fees. This is the result of Big Oil at work in an attempt to kill mass adoption of the EV.

Even if we could figure out adequate generation and storage (unlikely without nuclear,) I dont think any electric standards would apply to antique cars, that idea would be a third rail issue for any politician proposing it, hence why so many laws are "going forward" types and items that existed pre-ban are usually grandfathered in.

Our roads are funded by gas taxes. EV's use the roads. I suppose you could eliminate the gas tax altogether and charge little old ladies who drive 5 miles a week and traveling salesmen who drive 1000 miles the same straight fee for using the roads but not sure that is fair either. Suck it up buttercup, you gotta pay your fair share somehow.
A bunch of people that don't know their asses from a hole in the ground making laws.
They are getting payed from the public coffers so it is nothing for them to just add another knee jerk tax.
Can't say for sure where big oil fits in but remember the EV1?
Auto makers fought the California electric car mandate and when the EV1 was discontinued they all were crushed.
The patent to the nickle batteries that were state of the art at the time was bought by Mobil oil and locked away setting batt technology back a few years.

Who are you telling to suck it up? The point is Big Oil is going to do what they can to kill mass adoption of the EV market. It has nothing to do with "paying a fair share".
You just made the point. Big Oil buys the tech and shelves it to keep EV advancement suppressed. Tesla is now the dominant global market maker in the EV market and Tesla owns 100% of their battery and software technology so the way Big Oil is attempting to control the EV market now is by doubling down on massive short positions against Tesla.
It sucks to see it happening but the oil companies are more powerful than most people realize. They could literally afford to dump cheap oil onto the market for years just to drive down the cost of manufacturing goods and providing services which would completely kill the EV market.
Remember when Exxon was in the news for making $96 billion in PROFIT in just 1 quarter? That's $32 billion per month in profit they made. Can you imagine the monthly costs to run oil refineries? And you still have $32 billion in profit at the end of the month.
They have absolutely insane power.
Anyway...back to the OP...this is going to be an amazing build and I can't wait to see the final results. I'm curious how the torque is going to be managed like one poster above said when off roading where we typically ride the clutch to inch our way over an obstacle.
Yes, I am anxiously waiting for the electric Toy to be finished.
AC's are brushless so they may stall better than DC's with a commutator.
I know for a fact that if you hold a DC motor at stop with power to it too long the com can get hot and warp.
Depending on how long you hold it, it will still run but eventually tear up the brushes.
