Wiper motor recommendations

Hi guys, can anyone recommend a certain wiper motor? Or from a certain manufacturer?

Have a look on NIDEC motors in my signature: cheap 35€, good torque, irreversible and already ground isolated!

Mind that any other wiper has to be ground isolated!

12v for sure, large passenger car, earth isolate it , no specific model

After that , look into big worm gear motors like this http://www.ebay.ca/itm/GEAR-MOTOR-1...ILLCRAB-POT-PULLFEED-150160-rpm-/370915744975
http://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html 12v version
And i suggest the Pololu JRK http://www.pololu.com/product/1393/ , it will run 14v at 30 amps continuous all day with heat sink on the big chip and fan cooling.
Some of us run the jrks at 40 amps peak, no problem.

Irreversible is no good as we reverse the motors and you may end up chewing gearing out for the sake of holding the sim steady when all power is off.

Last time I bought wipers I went with new ones instead of salvaging car junkyards. First time I've went buying used ones, they were cheaper, but not completely identical and one was weaker than the other so I had to lose a lot of time on making good profile to adjust speed for both motors, it was unnecessary pain in the a**.

These are the ones I've bought last time

I got two of them, new, identical, performing the same.
But they need to be ground isolated.

Thanks. I was just checking that its not too important to get the wiper motors from a truck or bus.

Golf wiper motors I tested were too weak... Go for monospace, bus or truck models ;-)

So do I need Irreversible or not Irreversible ? as i have had both answers . Thanks for all the help guys

If you get something that is not designed to be reversed and you try to reverse it, it will either break or slow significantly on direction change. Bad idea, not recommended by me.
The idea of irreversible is for aesthetic reasons, people want the sim to stay at a centre point when its off, not have it slump down.
Without going into to much detail, generally wipers are a bit stiff anyway so they will hold a bit when power is off. irreversible is not recommended.
And avoid buying something that is 24v and you only running 12v through it. Half the speed, half the torque. Use a 12v motor for 12v, or a 24v motor for 24v. You get the best response that way.

Ah I see, thanks for that. As for the irreversible for aesthetics, Im not fussed how it looks when its not on, so thats not a problem for me. So its best for me to go with something that IS reversible. Thank you.

Sorry, but "irreversible" doesn't mean "can't be reversed".

Irreversibility means that under (normal) load and without power supply, the gearmotor won't turn. It's due to angle of gear and some other factors...
Irreversible gearmotor are meant to go both ways. It does not meant that they are limited to one way.

And I agree that multiple and frequent reverse stresses are the worst possible treatment for gearmotor... so a really good motor is required for racing sim!

Nota: for information, wipermotors when mounted on vehicles, are turning in a single way and the alternate movement is given by rods system.

Am I rightin thinking that any use of a worm gear will make the motor irreversible?

Ignore my last comment. Just been reading about worm drive motors.

Basically all I can recommend is that you check the internal gearing if possible, most are nylon, after a couple of weeks with a decent racing profile the normally metal worm gear chews out the plastic gear badly. At slow speed this might not be so evident, wipers are a good option to give it a go, but can t recommend using them for sometime , my first ones which had steel internals eventually failed in 60 hrs.

Beware running a 24v motor (bus/truck) is not a good thing for them, they are designed for 24v not 12v. Plus speeds and torque more than halfs.

Dont be discouraged in using them , if you take the right electrical precautions and balance you sim properly they will last long enough to play, but I tend to thrash my sim daily for a couple of hours at a time, and I do set my profiles to be quite harsh, if i hit a wall i want it to just about toss me out of the seat. You can always upgrade later, here in Australia the only new type wiper I could find were alot dearer than the motiondynamic units. Not the same in other country thou.

Thank you so much guys, This is such a friendly forum, and so helpful

Not sure if any truck wiper motors in the U.S. are 24v, I have never seen a 24v based rig. Peterbuilt, Kenworth, etc are all 12v, or they use an air system as well. This might be different in the UK or AU though.

Here in Australia, there are both 12v and 24v. I got in contact with a truck wiper supplier a while ago before I found the current big worm gears.
Wiper motors still have one thing to remember - speed. 50-60rpm, that 12 and 24v. So if you run 12v through a 24v motor, expect it to be slower in speed, especially under load. Like nearly half the rated speed.
Wiper motors are a good start, especially if you can find them cheap.
In the beginning after 5 calls to wrecking yards, the price went from $90 each second hand to $10 each second hand. So I burnt up many $10 wipers on builds. and I had to earth isolate each one
Yes I chewed plenty out as well after a while. Even with a well balanced frame, they failed. Hence now I run bigger motors.
But still , wipers were a good start.

Does anyone know if these http://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html are available in the uk/europe? Or something similar?

http://www.motioncontrolproducts.co.uk/ try these guys

Hi Nath. I have a couple of brand new 90ZYT-155-12 12V motors plus MCP4 gearbox from Motion Control Products. I'm in the UK so can let you have these for £55 each inc. carriage. I also have some timing belts, pulley wheels and Rod Ends. If these are of interest I can let you have prices.
