Hi,

I'm trying to track down a suitable motor for an EV build.

I've found this wreck of a truck thing.

Apparently it worked before the batteries ran out?

Anybody know what kind of motor it is?

DC? AC? ACDC? (bad joke)

I was kinda after a series wound dc. But they're looking tricky to source.

The three conductors suggest a three-phase AC motor, but they could just be rotor, stator, and field terminals for a shunt (SepEx) motor. There just isn't much to go on in that photo.

I think the tow truck is from 2006.

So maybe your right. It's probably to modern to use the old DC series wound.

I take it, it's not suitable due to controllers can't be modified with AC motors?

It's from a bradshaw t10 tow truck.

I didn't find anything about the motor type or controls, but the Bradshaw T10 tug (or tractor) apparently used an 80 volt (nominal) lead-acid battery... so there's a bit of a hint about one characteristic of the motor.

While these tugs are still around, the manufacturer apparently is not (at least the website is not functioning). The Wayback Machine has archives of the Bradshaw web site, but only starting in 2017; by that time their tow tractor range did not include this model, and details of the models of that time are not archived.

thanks for this...I've searched all over for the motor spec, but there isn't much info about.

Apparently it can pull 10,000kg at 12mph

but not a whisper of the type of motor.

If it is an AC, I wonder how feasible it'd be to use?

I mean I'd be happy enough knowing I have the most powerful 12mph car on the road.

that web arch website is pretty cool!!! epic find!!

There's a "baby locomotive" T10 for sale in Croatia. They claim it'll pull 25 tonnes, which doesn't make sense - the T2500 is 25,000kg. A derivative of the T10 is the T2500.

With that tow cap messup, not sure I'd trust their numbers. The company's still in business - call them.

Be careful with level towing vs automotive with wind drag and grade holding at a certain speed if this is destined for a car/truck.

Wawa is a distributor of various brands, including Bradshaw; Bradshaw itself may not be operating, but that's good information from Wawa.

English appears to be the most common second language in Croatia, so a call might be worthwhile.

The naming makes sense to me, if they just changed from an old scheme unrelated to capacity to new scheme based on towing capacity in tons with a couple of zeroes on the end (just to indicate a new numbering series)
