MY 2dof wiper motor seat mover

No video yet ... the construction is not complete ... because i didn't have a lot of spare time to go on with the build.

No Cad either.

The steel sheets are 4mm thick.

You can see the chassis dimensions in the following pic:






The motors are designed to work From -45 degrees to +45 degrees from rest (horizontal rod) position.
Why only +/- 45 degrees?
If you go above 45 degrees from resting point a lot of linearity is lost. That is above +/- 45 degrees ... the motors turn but the tilt speed is very slow compared to the rotation of the motor.

So a combined use of both motors can output a maximum of about :
10 degrees LEFT or RIGHT,
OR
5 degrees Front or BACK,
tilt on the seat.

Thanks for the pictures and explanation, I will ponder the next step.
Just one thing, the answer is not the most efficient engines in both torque and rpm, working at 24V?

[pipis2014]

Yes, you are right, if the motors are powered with 24 volt PSU the motion is faster, the torque may be A little more and the amperes will be probably less.

But if you want just to tilt the seat and not a platform of seat-steering wheel-pedals then the motion is ok.

If you want to be able to feel vibration also, then you might need 24volts.I will answer this as soon as I complete my rig and have it working with

sirnoname's newest firmware.

Also, the used 600 watt server 12 volt PSU is very cheap compared to a 24 volt 600watt PSU.

Great job here!

Hi, great job!! Do you have a video moving under load?

[pipis2014]

I will post one as soon as I can.

This first clip is just a test with me sitting on the seat.

Its purpose is to demonstrate how quiet the motors are with racingmats ultrasonic code.
