Im in the uk and ive been phoning and visiting the local forklift specialists. They all have the same tune. The big 12" motors havent been seen for 10 yrs. They all went to recycling. Now fork trucks use 8"

He had loads of those to sell me.

Im converting a mazda rx8 it weighs 1350kg

Would an 8" be ok? Say i used a 120-140v battery?

Or would anybody know how to source a bigger motor?

Im looking on Alibaba and found this...

https://m.alibaba.com/product/525516621/11kw-144V-electric-car-dc-motor.html?spm=a2706.amp_sc_detail.recommend_products

I suppose it all rings correct because the tutorial vids are around 8yrs old so maybe the big dc motors are hard to find?

Thx for any tips or hints.

Here NZ - the most common size seems to be 11 inches

That is 11 inches in diameter and about 100 Kg

I did manage to pick up a 9 inch - about 60 kg

Saying THAT you don't want a new forklift motor as it will be AC and no good without a matched controller

You want a motor from one of the forklifts that are being re-cycled - probably 20 years old

My own experience is that telephoning is useless - you need to VISIT the forklift repair people with a pocket of cash

The actual repair guy (not the office wallah) will have a couple of spare motors Just In Case - you are trying to wheadle one of them off him

Thanks for your reply.

This is terrible news. Ive bought the car thinking the motors are super easy to buy.

I cant afford an all singing ac setup just yet.

These 8inch motors look like pump motors. I think they are from the old style fork trucks just not the traction motor. I wonder if i could put 2 together to make 1 motor? Hmmmm

Id need to look at them again.

Mr Damian Maguires €1000 ev conversion is fantastic however now im realising he is using parts from under his work bench 😁

Ok tine to role up the sleeves and do more digging.

That's how all really cheap projects work: they don't count most of the actual cost.
Actually I think Damien was picky that he actually bought this stuff, because the £1000 car was a challenge project and he wanted it to be fair.

The only think from under his desk were the power transistors, and he said if anyone really has trouble finding any, he'll ship them some for free.

Its a great set of videos however he said he already had 3 dc motors under his desk which he got years ago before they were rare by emails companies with fork in the names. These motors havent been seen for 10yrs is the constant responses im getting. They go straight to scrap for the cash.

I somehow find that hard to believe.

Forklifts last decades. When I went to the scrappers last year, I was pulling apart forklifts from the late 60s and 70s.

People are probably skimming your emails and wondering about them having replacement DC motors in stock, and telling you no that they don't do that.

Listen to the advice. Emails probably aren't going to be helpful. Actually go down to the shop and talk to the guys in the back or make a phone call. Start off by saying it's for a project and wondering if you could strip some parts off something that's garbage to them, or if they have old motors you could use.

You might have to wait a month for something to come in that they're scraping, but, motor salvage isn't that highly valued, especially compared to 5-15 years ago.

This isn't some esoteric use-to-be, probably once a month someone comes here and asks for advice on pulling a forklift motor, and I can't think of anyone who tried and failed to succeed on their first attempt at their first yard. Maybe you're in a weird zone where what works for the rest of the world doesn't work for your area, but, I'm doubtful. I suspect it's your approach.

Thx. Ok my hopes are increasing slightly. Im starting to see old forks landing on ebay. Nothing local enough to me to jump on.

All the breakers dont stock traction motors. One guy phoned me from my email send out. He said he has a supplier and will get me some quote...he wouldnt give me his suppliers name though.

I think im going down the buy an old fork truck, take out the fun bits and scrap the rest. Hell, i might even build my own foundary and use the steel to make some new sils for my car.

But i started another thread with my experience procuring a dc motor in the uk. Your right, i beleive patience is the key here.

That was how I started
I bought an old forklift - cheap and took it to bits
The battery is always salable as is the main mast and hydraulics
a friend made a vandal proof post box out of one of the oil tanks
but the motors were not suitable
When I tried to sell off some of the bits I ended up in touch with a repair yard that had a decent motor

Ahhh cool. Your not the fella who did the web post regarding a fork truck. You hot 2 pump motors ans a traction motor? If thats the case, you inspired me to look for the full trucks.

Why wasnt the motor suitable? Didnt work or just to big?

One concern i have... is spending lots of time and money on an old fork motor. Then like u...it not being suitable or the brushes arent good and u cant get hold of any.

I think for $1750-2700 for a kostov might be another good option. But then then the whole point was to make something cheap to learn how the process works.

Well...lets just see what turns up.

They will usually be series wound or SEPEX in these sizes.
I find it difficult to believe that in the UK there is nobody that has odd bits laying about. Check motor repair shops that rewind, surplus places, etc. It all requires you to actually go there however, instead of sitting at the computer

Hi
I bought a three wheeled forklift - bad idea
the drive motor would have been OK - but it was in a huge and heavy square casting - pump motors are a pain and rarely useful

I think we're all sending the same message.

"Try the steak it's delicious"
"Okay good advice. So I ordered salad and I'm disappointed. Does anyone know how to order a meal here that will taste good?"
"Yes, the steak, just order that, it's delicious. Dozens of us have ordered it before. Trust us, it's good every time."
"Oh I see, that makes sense. So I ordered garlic bread and it's just not as good as you guys are describing the steak to be. This is really frustrating, I just want a good meal."

:p

Me too GE That sounds like heaven.

In uk, they they get good money for scrap so the big motors go straight there. Imagine have a load of motors on the floor taking up space or a big wad of cash in your hand?

I sent the emails to 40 places. 6 people have called me all saying the same.

Its hard to drive to all these places. They are scattered here there and everywhere.

Im starting to nail this though and a great opportunity has brought itself forward. I think im about to buy 4x 48v dc series wounds motors tomorrow for £400 they are from 1996 they look in decent nick fron the pictures. Might get the pump motors too. Maybe even the potentiometers if i can.

Excited. Super local as well.

Its not easy over here in the pond. Plus what im doing is super rare end.

Bought a pack of 10x AA batteries which adds up to 12volts to test them!


😁

Thx piot... motor rewinds is a great idea! That sounds far better than fork lift repairs. I wouldnt have thought so but u could be right.

Any way im making more progress.

Salad is better than steak. Ill stick with the dressings 🥦��

I've found a scrap yard in the middle of nowhere Utah that has a bunch of Hyster e50x forklifts. I bought one motor already. Hearing how rare they are I just asked him and he still has some. I'll head down there in a couple weeks and grab as many as I can carry.
