car vs. truck wiper motor

I want to motorize my son's joyrider for use as a roller coaster simulator. Want to go with Thanos' setup utilizing wiper motors and pulley/belt drives. After some research, I determined that the motors Thanos used were a 1985 Nissan B11 (Sunny)--which are hard to find. However, the comparable American version is the 1985 Sentra, with rebuilt wiper motors readily available. Someone mentioned truck wiper motors might be better. If so, what kind of truck? Pickup? Full size? Semi? Any advice is appreciated.

You are probably overthinking the wiper motor selection. There isn't anything special about a 1985 Nissan B11 motor. That is probably just what Thanos had laying around, or could find easily and cheaply at the time of the build. Many wiper motors are pretty similar. A SUV or pickup would tend to have larger windshield wipers than a small sedan like a B11/Sunny/Sentra, so would usually have a more powerful motor. Wiper motors are sometimes a bit under powered for a sim, so a larger motor from a bigger vehicle would be better. As long as your Joyrider is well balanced and you aren't trying to move it too quickly, I think you can get away with lower powered motors than a seatmover or 6DOF race sim. I think with a Thanos setup you will probably lose some of the small movements from a roller coaster, like the feel of a wood track. But the sweeping turns, hills, and drops should work well, and shouldn't require huge motors to pull off.

I'll be getting No Limits 2 up and running with my simulator sometime next week, and I should be able to provide more specific feedback then. My sim isn't quite a Thanos/Joyrider, but it is a lot more similar than most simulators here.

You're probably right about the overthinking part. Just want to make sure I do it right the first time. Have a limited budget (spending my son's bday money). Reason I've been somewhat obsessive about the motor Thanos uses is seeing it in action makes me think it has good response for a rc sim. There are very few joyrider projects out there compared to seat movers, so I do not get to see much in terms of performance. Also, there's little in the way of specs on wiper motors out there I could research. I have no problem going with truck wiper motors, just need to know what size of the truck. I can pretty much go from there. Thanks for taking the time to help me out, and I look forward to seeing your finished project.

Which I used in my prototype 6DOF they were of a van Citroen Jumpy or Peugeot Expert and are quite strong, have double gear in the gearbox.

Nice! Are they 12v? I live in the US, so Peugeot and Citroen are not available here. I wonder if these, if easily available and inexpensive, would work for me.

I really recommend these motors over wipers.

Yeah, I've looked at those, and I believe you're right. Out of my price range, I'm afraid.

Yes, much better.

Hi @SpaceKaseJase, I know what you're saying about having a budget, but the motors that you use are among the most important parts of the simulator. I would recommend that you find the money somewhere and buy the best gear motor you can. I can endorse the motors that @shannonb1 recommended as I have them in my sim and they are very capable. Beware of buying something that's under powered or doesn't quite do the job. Remember, buy cheap, buy twice!

Sound advice, my friend. Suppose I do scrape the money together for these, at best I will have about $200 for the rest of the electronics and hardware. I know Arduinos are cheap, but what about the drivers and POTs? Might I be able to plug the simulator in an outlet for power or would I need a power supply also? Just trying to budget my son's birthday money.

Gold, my friend, gold! You guys are so helpful! Read the disclaimer about using Mm and Arduinos. Though I am a complete noob, my friend owns his own robotics business and can help with the setup/programming.

I really recommend the JRK solution. They are 99$ a piece but they are an all in one solution and work great with 1.3 and 2.0 versions of simtools.

If I might I would recommend the following.
These are 40a but I use the 50a just because....these are 49$ shipped with prime from amazon. With the server power supplies I had spikes and they would power down.

For the controllers I prefer JRK, amazon or straight from Pololu.

and the motors I linked in above, I like the 50:1 gear ratio as I'm 240lb. They hold position better when at a rest as well.

For the Hall Sensors I recommend the following...

Fans that I use....

Why do I prefer these motors.....I used plenty of wipers...gears break, motors overheat, you have to deal with removing the earthing wire....new ones can be around 70$...used ones around 30...You need to find a pair....a car only has one motor so you need to find 2 junk cars of the same....they have to have one motor reversed where as the motors I shared can be mounted identically....wiper motors are weaker and will strain..

Why do I prefer those power supplies....I spent 100$'s on used power supplies....some worked under full load...many failed and would drop out a motor....no warranty..the ones i recommend look great, have simple screw in headers and can also power fans on the secondary voltage plugs, no soldering required.

Why do I prefer the JRK....rock solid performance, an all in one solution, software works great, no programming involved, calibrate to the motors and go...great price for what you get..puts some heat sinks and fans on them and you're good to go.

why do I recommend the sensors....they are 360...they wont break if you pass a certain point, you can thrash and make mistakes with your motors and you wont kill them...relatively inexpensive...around 14$ a piece..

Motors...Around 200$
JRK around 200$
Power supplies Around 100$
Sensors around 25$
Fans around 12$

Adding it up it can be pricey but the options I have supplied are quality parts that are less likely to give you issues over time. I have been at this since around 2005 and this is my experience over time in getting to a system that is solid and dependable.

Let me know if I can answer any questions. Happy building

Wonderful! I think I can save money without going for JRK only because my buddy knows programming and said he could help me out. I assume MM and an Arduino Uno might be the way to go. Wdyt?

Completely up to you. I have used both. a lot more wires that way. More code and in my opinion that adds some level of latency and more areas for you to run into headaches. As long as your buddy is going to be there every time you have a question then you should be good.

Hopefully--we'll see.

So I told my friend about the motors you recommended, which I will most likely obtain (anything worth doing is worth doing right). This is his response:

...we're going to need the no-load and stall current of these motors. If it's not listed, we'll need to hook one up to our lab power supply and obtain this info. We must have this in order to size the motor driver FET's correctly. After we have that, we can do a quick test with an arduino and FET driver board to see what kind of performance we can expect."

Do any of you know the no-load and stall current of these motors?

Edit: found the info

So the "Stall current" is not listed for those gear motors. Anyone who uses them have that info?

I do not sorry.
