12 v wiper motor fix.

After picking up these 12 DC motors i was having issue figuring out what plug works for what. talking it apart and finding a circuit board inside and things being in reverse . I decided to attack this issue with a Hammer .
i ripped out the circuits leaving the essentials and soldering in direct wiring for the fastest speed on these two speed motors.

This is two Dc motors of possibly of six for 2 Dof to 6 Dof. next will be working on getting the pots afixed some how ?

You don't want it at the fastest speed needs to be the same speed when polarity is reversed also the casing will need isolating from the circuit

Interesting. I did notice the speed in reverse was the same speed but being the newb here , I love the setup you have and want to go your route with 6 Dof. right now still learning and soaking up everything i can as a sponge.
the isolation of the case is kind of confusing to me? should i be , use ground the case separately along with the regular two wire setup ? Im not sure , i don't want to burn up the motors and guess i need to do much more investigating.
anther question is whats the right way to connect the pots to the drive? I guess little steps are to be the right way to go .
i thank you for your input and welcome more as you give it.
i have some many question and only have the sorting through forums and videos to watch . Thanks Sam

Ok I imagine the circuit can reverse the high speed but may reduce the torque I have wired mine directly to opposing brushes have a look here for isolating the circuit https://www.xsimulator.net/community/posts/90814/

The pot mounting is a headache I don't think my concept would work for you but there are plenty of good examples just have play

Thanks for the quick reply, i open the motor and trying to go by the diagram you gave me and was going to ask that what you have said, next. but really im curious of how you attached the extension arms to the motor arms? with rod end bearings?

I was looking at the cost and there kinds high but if needed then thats what it costs. just trying to piece things together without making to many costly mistakes.

The route I went down was to use the existing ball on the wiper arm to attach a ball socket to you probably have 13mm ball on the end of yours then attached threaded rod to it

https://www.sgs-engineering.com got mine here reasonable prices and actually tight unlike cheap ebay crap

I had to run and look for some holding brackets for the motors , hope they work and thanks for the link to sorting out the ground issue. it doesn't exactly match my motors but theres only one wire that i see leading somewhere else. i havent cut anything yet, just want to be really sure before going forward.

Do you have a multimeter?

Basically from this picture you want to solder 1 wire to red and 1 to blue discard yellow the blue uses the case as it's wire and thats the thing you dont want so this would be the one to cut then make sure there is no continuity between each wire and casing how you achieve this is up to you I just soldered both directly but you only need to do the blue as the others are naturally isolated

Yeah i have a multimeter. i used a light diode to find that it was case grounded. i didn't think of the multimeter.

Oh good well glad you're on the right track I'm no pro still learning just more software side of things now but anyway all the best with the project will be interested to see what you produce it's well worth the effort

Thank man for the help. i sure hope i can bend your ear in the future.

No problem always keen to help where I can but there are many more experienced here which will give you a broader sense of things there is some really amazing stuff on this site

I agree ...................thanks
