I'm new to EVs, having never owned one. But I'd like to convert my ute/pickup on a fairly tight budget.
I'm in Australia, where we don't seem to have a lot of old forklifts to salvage despite looking around.
The scrap yard has hundreds of AC synchronous, single and three phase motors. I'm wondering how viable these would be?
My intentions at this stage are to run one large, or two smaller motors side by side bolted directly onto the rear differential. The differential has a 4.56 ratio and is an LSD. I would weld brackets and attachments to a spare diff housing and support the front of the motors via a short custom suspension strut onto a new crossmember, or solid mount the motor and make a driveshaft.
I know the preference is to keep the gearbox (manual 4X4), but id realy rather get rid of it if I can get a motor/motors large enough to not need it.
The vehicle is 4X4, I have no intentions of keeping it 4X4 with this conversion, but if there's the possibility of powering the front diff that would be fantastic. Maybe one motor on each diff??
How suitable are these AC motors from the junkyard? From what I've read, a lot more power can be pulled from these motors with the right controller.
From my research, AC is ideal, however the controller can be complicated. I am a younger engineer, and a hobby electronics guy, am I out of my league here?
Look forward to hearing what you guys have to say.
