- Taking a very detailed look at wiper motors, and how to use them in your own projects. I have been using them for my Acrobots, and Werner van der Zwan has been using them for this kinematic sculptures.
It helps me a lot if you subscribe, and you'll also get more DIY and robotics content :)
Werner and I met at V2_ Lab for Unstable Media in Rotterdam, which supports Werner's Unconventional Self and my Acrobot, two projects which use wiper motors!

That set of terminals with the intermittent contact is for parking the wipers. Did you notice when you stop the wipers they always go back to the home or park position, where the wiper blades are in the home position. That is the purpose of the extra set of leads he was showing. This can be very helpful in homemade mechanisms if you want it to return to a predetermined position upon completing a function. Thank you for the video it was very well done
Yes, it is really a luxury to have this position sensor built in!
Good video! I'm always looking for tips and new ideas. About 8 years ago I first used a wiper motor as a servo for controlling the steering for a radio controlled full size car. These cars are used to stage crashes for the local public safety training center for their accident reconstruction classes. There was no manual for rigging these kind of projects so in the beginning it was a lot of trial and error with homemade parts. The wiper motors give about +/- 20 degrees or so of steering wheel movement which is usually plenty to keep the vehicle on course. The torque is more than enough to turn the wheel on a non-running car with no power steering (it's being pushed). Throttle can usually be done with a standard r/c servo and braking is just on/off with a pneumatic actuator. I enjoy the challenge of rigging up different vehicle models and then controlling them down the track is a rush!
I put together a short video of some of our crashes we've done in the past if you might be interested: ruclips.net/video/Td7kBKz7JLM/видео.html
Neat channel, very unique. Informative video, thanks for sharing. Best luck to you and Werner.
Thank you :)
Very nice, I am designing a trolly for an overhead chainhoist for the purpose of using a wireless tv remote to push/pull the chain hoist along an I beam. Your engineering effort has made my design "stupid simple". Thanks in advance.
Another great video, thanks for helping me
Good info. Definitely going to dabble with this.
Good luck, I hope it goes well!
Brooo where i can find them please tell me
@@Gnome21353you can order them online or buy them at a scrapeyard
This is great content! Love it!
Thank you Mark!
Great primer; thanks!
You're welcome, thanks for watching!
Leuke video, ik houd deze in mijn achterhoofd mocht er een leuk idee te binnen schieten :)
Ja top! Ik hoor het wel :)
Very informative! Thank you !
Glad to hear that :)
literally perfection thank you so much
Aw thanks so much!
Very nice explanation video Hap!
- Theoden from PJ
Thanks :D
merry christmass, daniel!
Hey b, thanks, you too!
Hey Daniel, super video - found it on HaD!
I am a bit scared of Werner's power supply with the open mains terminals, though ;) Maybe you (and he) should have a look at PC power supplies. They are cheap and they can provide lots of Amps at different voltages (3.3V, 5V, 12V). I guess at least the 5V line can provide enough current to drive a windscreen wiper motor slowly.
On HaD!? Again! Haha I would never know this without you :D
I also find these power supplies scary. I had bad luck with a PC power supply that I spent too much effort on to try and get working, but now I have a proper bench supply that was well worth the investment :)
Comment for the YT algorithm but also good job, very useful info.
Always happy with the boost! :D
Hi i am looking for using them in a hand operated manual car vlutch system. Can you help me with that
Kudos, good job and that cheeky subscribe subliminal at 11:37 :)
hihi, did it work? ;)
Beste Daniel, Waar ergens in Belgie kan je de IO53A02 controler kopen?
How would these do in a RC lawnmower application? Would they be able to handle having the wheels directly mounted to the output axle?
Yes, I don't see why not :)
What power suppy are you using?
Amazing material!
Could you share the circuit and the code of your example at 20:50?
Sure, here you go:

Love it, thanks!
Glad you like it :)
@@DanielSimu Out of interest - what do you do for a living?
@@DomBurgess I'm an artist. I perform, I teach workshops, I make installations, I present videos, I give technical advice... currently I'm mostly busy with my Acrobot project, for which I originally used these wiper motors.
@@DanielSimu Awesome! I'll check out the Acrobat project.
Have you tried Loctite instead of epoxy to add a coupling nut - there are high strength versions to hold parts to shafts - and they can be undone with moderate heat. Interesting stuff, thank you.
Yes, I tried this before I tried epoxy. However, even the highest strenght Loctites were unable to hold the 25Nm torque on these bolts. It is really difficult to imagine what kind of force can be exerted on this shaft!
I'm thinking of building a motion rig sim cockpit how much weight can two electric motors handle. my weight is about 115kg and together with the rigging it will probably be 200kg
You will need to calculate how much torque you require from the motors. These motors typically have about 25Nm torque. Weight influences torque, but so does the length of the lever and the angle, etc.
cool video i like
Thank you!
Want a stronger one? Get a washer/dryer motor.
Not geared like a wiper motor
Can we use two 24v wiper motor to make electric wheelchair?
With 3.143:1 sprocket ratio
Are there any brands or car model motors that do not use plastic gears?
I've looked really hard for them, and was unable to find any. They do exist, Doga creates one, but I don't think they are used in cars. Also they are nearly 10x as expensive as the ones I typically use...
@@DanielSimu Thanks for the response. Going to use a wiper motor for a lead screw on a lathe. It is a common conversion. I guess the plastic ones must hold up as most of the conversions on RUclips don’t specify any particular motor.
@@Wes-tg5xw And once you have the lathe, you may be able to make your own metal gear? ;)
Enough torque to break bones. Definitely crush fingers. Have fun, but be careful.
Definitely!
out of curiosity, which motor are you buying?
A Cubemars module. It will be the topic of my next video!
cool!
what is the difference between a 24V and a 12V motor
The voltage in 24v is higher but the current draw is lower. 24 volt systems for HGVs and bus vehicles.
💖💖💖💖
maybe you can get a 3d scan done of the plastic gears and have them machined
A 3d scan will not be accurate enough, but it is possible to measure and draw it. However, this will quickly get expensive, and possibly risky as I don't know if other parts are near failure too.
Luckily there are other motors that have all the kinks worked out, see my video about Cubemars motor modules
Great video. Do you have a link for the backplate rotary encoder?
It's the AS5600
Yes, I saw that. I was trying to see how it was mounted to the output shaft. Do you have any links/pictures of that process? (I found the link for the servo one that mounts to the motor shaft)
@@Jekyll-Labs I don't have anything useful I'm afraid. If you give me an email address I'll be happy to forward the STL of our plate, but it's unlikely that it will fit your motor, and it's not perfect fit for ours either (but good enough). Either way, it's just a little plate that holds the encoder, the magnet is glued onto the shaft.
