Seat mover With Traction loss

Hi, I am new to racing motion simulators and I am interested in building a one from scratch. My intention is to build a seat mover with two DC Motors. Maybe also add to it traction loss to the the whole frame. I ordered the Arduino uno v3 and Moto Monster Boards and it may take about a month for them to arrive. I am thinking to use DC scooter moters 24V 350W ZY1016. Can anyone tell me if they are ok.

Hi @Zubidat
I don’t think moto monster will power 24v motors fully.
Best of luck with your build

Hi
Since I am new to motion simulators , I have decided to first start by experimenting with motor control. I have ordered the following parts :

Power supply 110v/220v to 12v 10A 120w
DC motors 12V WG73bd76 30nm 180 u/m 80w
10k linear rotary Pots single turn
ARDUINO UNO R3 REV3 BOARD
MOTO MONSTER BOARDS (2)
Heat Sinks and Heat sinks paste

It will take some time for these parts to arrive since I have ordered them from abroad.

Hi

I have bought a second hand DC wiper motor from a Seat Ibiza Car. It was very hard to isolate the ground from the body. I am not sure if I can use it. It seemed a little slow.

Hi,
For your motors I suggest sabertooth 2x32 or better 2x64

Your psu choice is too weak.

Thank you for your advise. You are right I will get a 12V 30 ampere PSU.
My question is : Will it be enough for three motors or do I need stronger PSU or should I use more than one PSU.

Today I started working on my frame.

This is that base for the traction

This is the main frame

When I used wiper motors in my setup they would see loads of 10-15 amps each with movement under load with even higher peak draw during rapid movement, I had a cheap 30 amp standard PC PSU and it would go into protection mode with just one motor occasionally, but a higher quality one might not suffer from the 'protect mode' issue.
A 30 amp PSU in my opinion is underpowered for the task of two wiper motors, I definitely believe it will be underpowered for three.

A lot of us use server power supplies from Dell PowerEdge 2950 or similar. 750w (12v 62.5 amp)

Here is my updated frame

Hi everyone,
I only have few hours once a week to work on my project. So therefore it is taking some time.

Here are some Pictures

hi there
Was looking at your sim frame you are welding up. your design looks very similar to the first frame I made bout 5 years ago and thought I would point out some of the problems I had with it to help you and perhaps stop you from having to make another later when you get everything running. obviously there are no measurements on your pictures so I'm guessing the size of your frame to a point. I am also using 2 x moto monster and simtools excellent SMC3 software.

firstly the frame seems to be a bit short at the back behind the seat. I extended mine to give more leverage on the connecting arms to the motors so they are not lifting rather than pushing as they should be. it was ok until I got 120kg max pressure load cell pedals then I could stop the seat from moving under braking

secondly the uv joint under the seat seems very high. I found that with the over steer axis on you may find the sim tip up sideways as your centre of gravity will be high in relation to the width of the sim at the back where you have placed the casters. A work mate of mine tipped my sim in a crash and was left leaning against the wall next to the sim ( funny now but could have been dangerous with a child in it). ive got a height of 120mm between base of sim and bottom of seat frame. I used the uv joint from the up down adjustable steering column of a car for this.

thirdly and this is just personal preference I used casters on my first build and found them to be noisy. I used metal bearings as well but the noise was worse. I now use 76A rollerblade wheels and pitched the ends of the back bar to 12 degrees of straight to make them track right as the sim turns in a slide. they are really quiet now.

as for your power supply question I currently use a 500w supply and its not powerfull enough for 3 motors. it may be ok if you have a soft brake pedal but load cell pedals which u will eventually move to if you haven't already will cause problems under braking.
your sim so far looks good and wish u all the best with your build. if you have any questions feel free to pm me and ill do my best to help
regards matt

Hi,

Thank you for your comments. This is my first simulator and I do appreciate any help. I will look closely at you suggestions and I will make the necessary changes. I will soon have some questions. So, I am looking forward for your help. Thank you very much.

I have worked last Saturday and added an adjusted steering wheel column (Up , down , backward , forward). Also, Added a mount for a gear shift.

Todat I think I have finally figured out how to test my motors with Simtools Axis setup. I Have tried to Adjust one move at a time. For example, I worked with Roll until I got to configure it right. Then, I removed it and worked with only Surge to see what it does. And finally I added all together.
