Would this electric motor fit in an IRS commodore?

Every time I drive past a bowser this idea looks more attractive. Would someone who knows a bit about the rear diff setup in an IRS commodore take a look at the spec sheets for this UQM motor and see how difficult it would be to fit in the back.

FWIW the drive plates are 18 inches apart.

They have other motor sets without the controller on it so it might be better to just keep the motor up the front but I like this one.

wouldnt know, but a good idea though

I remember seeing some show car which used commercially available electric motors, mounted one in each wheel. They doubled up as drive motors and regenerative braking systems, all in one. The output was something like 400nm of torque at each wheel...put one of those at each corner of a Monaro body with some suitable battery packs down low in the vehicle and watch the fun...the instant torque of electric motors would make it a pretty good ride...

I somewhere have an old clipping out of an Australasian Post magazine. Some old guy who had been an electrical engineer with the railways for years made up an electric car as a "retirement project". He had used an ex-railways three phase electric air-conditioning motor and a bootful of normal car batteries in an old Mazda 808 fastback coupe (same shape as the pretty little R100 rotary). The engine was a fair size, and was hooked up with a simple accelerator system which would get it up to something like 80km/hr max, but it would chew batteries at that speed. However, cruising along at 50 to 60, I think he would get around 100km out of it before recharging. Not bad for around town running. I wonder whatever happened to that thing?

There must be ways of doing things if you only think about it in a suitably off-track way. How would something like a suitable high speed and high torque electric motor go just plonked in there in place of a petrol engine and driving through an auto box to a normal diff? Maybe you could do without the gearbox altogether if the motor had enough torque? Sounds like you're onto a very interesting idea there....

I've heard that on fully electric cars, accelleration = awesome, and top speed = not so awesome. I saw a car on TV the other day (in Monacco I think?) which is electric, it does 0-100 in around 5.5 seconds, but tops out at 170. It would be awesome for the city I reckon. The only thing I didn't like about that one was that there are bo brakes - when your foot is off the gas, you are braking. That'd piss me off for a while I reckon. Oh, It cost ~$600,000 from memory.

yeah the price would put me off.

That motor would go through a car battery soooo fast, but, could you not run a alternator off it (maybe 6) because it has such a high torque rating it mustnt bother it too much powering a few alternators, correct me if im wrong but wouldnt that be perfect??

I was thinking maybe a series of wind turbines set up in ducted ports throughout the body might generate enough ooomph.

I've read about some electric street/drag cars from the states, it seems to cost 20-30 thousand US to convert a car with all the good stuff to run a 12-13 second 1/4 mile. I also noticed the adr's for car conversion to electric are semi finished so at least the government is getting ready for it, because it wont be long now till it's all the craze

Nah, thats called perpetual motion, getting something for nothing. Its impossible according to the laws of thermodynamics. There is inherit inefficiencies in everything that consume energy (friction, heat, sound etc)
