2DOF Wiper Sim from Interview 2010

Re: Wiper Motion Projekt Protocol by Interview 2010

Mass = Ground ???

Because if you reverse the direction, +12V will be connected to your frame.

If your frame is connected to ground, get ready for fireworks!

Re: Wiper Motion Projekt Protocol by Interview 2010

yes i mean the ground.

i have 2 cables on my wiper motor.

1- cable is for the first gear for the speed.
2- cable is the second gear for the speed.

and the ground (-) is the whole case of the wiper motor.

(my motion frame is made of aluminium.)

do i have to seperate the ground of my wiper motor from the case?
or can i leave it like that??

thanks

Re: Wiper Motion Projekt Protocol by Interview 2010

You don't have to, but make sure the case doesn't touch anything metallic, and no chance of shorting it out while it is running.

Re: Wiper Motion Projekt Protocol by Interview 2010

Isn't aluminium good electricity conductor???

There is NO COMMON GROUND between the motors!! And NO common ground is needed to the TTL parts of the h-bridge!!!

Re: Wiper Motion Projekt Protocol by Interview 2010

I do not understand what you mean ..

I have read, i must cut the mass of my wiper Hausing .. (If my frame is conductive)

Re: Wiper Motion Projekt Protocol by Interview 2010

hi guys,

i can not find the wiper motor graund on this!
could you help me?

thank you

Re: Wiper Motion Projekt Protocol by Interview 2010

Did you measure if your motor wires actually connect to the case?

It is hard to say where the case is grounded. If it is grounded, the blue wire (and whatever is soldered to it) in going to contact the case.
You have to make sure that the red and blue wires only connect to the brushes, and maybe those coils around them, nowhere else.

Re: Wiper Motion Projekt Protocol by Interview 2010

blue) 1- cable is for the first gear for the speed.
red) 2- cable is the second gear for the speed.

and the ground (-) is the whole case of the wiper motor.

Re: Wiper Motion Projekt Protocol by Interview 2010

Then find the brush that is not connected to the wires, the grounded brush. The wires most likely connect to the 2 brushes that are close together.

This is the connection you have to isolate from everything else. It is probably grounded through all the screws, maybe it's housing is connected too so be careful! Might need to take the PCB off.

After you isolate the brush, you just solder a connection to it and that will be one of the 2 contacts, red/blue for high/low speed for other contact.

I'm not exactly sure ... maybe something here ..

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

Today I start my build the frame together ;D

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

weiter so!!

ich will mal langsam ergebnisse sehen...
Mein Wackelstuhl ist vorerst inne Ecke gestellt: GT5 und so

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

jop ich bin dabei

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

Hallo Interview
Respekt tolle Arbeit die Du da machst.Bin auch grade dabei mir einen zu bauen,bin aber leider noch nicht so weit und erfahren wie Du.
Hätte da eine bitte könntest Du so nett sein und die aktuelle Einkaufsliste von Reicheltbezüglich des AMC Controllers+H-Bridge+LCD posten bitte. :clap:
Die 3 Platinen habe ich heute schon bestellt bei http://www.platinenbelichter.de.Brauche ich die Brücke eigentlich auch die Du im Pic. neben dem lcd liegen hast?
vielen Dank.

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

danke

ja ich werde dir dir die Warenkorb liste heute abend fertig machen (icq: 331682744 wenn du hilfe brauchst!)

viel spaß ...

PS: TIP!! die erste seite habe ich auch aktualisiert!!! (WICHTIG) <--- bittte lesen

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

hello,

I am currently building on together!

and wanted to ask is if this is a disadvantage! (Or bad)
as the rod can be seen down at. (She goes inside!)

thank you

Re: 2DOF Wiper Motion Projekt Protocol by Interview 2010

You want to have 90° between the rod and servo arm when the seat is horizontal.

The further you go away from this 90°, you will get less linear travel on the rod, for the same angular travel on the servo arm.
At 0° and 180° you will have no linear movement on the rods, because the servo arm moves it side to side, and doesn't push it.

See: Sine waves.
