newby looks for plc and motioncontrollers

HI ,
I`m Henk from the Netherlands and building a Motionplatform for a Cessna 172,
I have bought a real 172M Cessna Fuselage and fitted it with Simkits instruments and real knobs /switches and so on.
I`m now nearly finished building a platform what looks like a big rectangular made out of steeltube 50x50x5 mm and connected by a crosscoupling to a
T- shaped frame 40x40x5mm steeltube for mounting the cessna to the platform.
Because of its weight about 550lbs,
I`m looking for a plc and motorcontroller with the following wishes
2/3 dof movement
suitable for 220-250 volt 1kw Hz50 aproxx 8 amp motors.
I can purchase motors and gears from work ,
I have looked on nummerous sites but all I can find are motioncontrollers for 12-24 volt motors
Please you can comment in Dutch/English or German but will answer in dutch or English because I can read/understand German but can`t write it

Welcome Henk!

Can you post some pictures? Must be very nice project!

These are 5.5Amp controllers:

It would be possible to change the mosfets to 10+ Amps..
For the controller you could still use an AVR or a PIC.

No, not at all

@Henk
As we dont have a DIY solution for AC motors yet, you have to find a commercial phase inverter for each motor you want to use, which accepts either analog voltages, PWM signals, or serial data for dynamic and bi-directional speed and control.

Riton and scottlolo89 are using Omron V7 phase inverters for example.

hoi Henk
Even bij www.indumex.nl kijken

Hoi Ad, kun je een lijstje maken ,, met de benodigdheden om een werkend platform te krijgen?
Hi Ad,
Please can you make a parts list of the things, I need for making a working platfrom(just for the international viewers )
groet Henk

For example:

3 AC gearheadmotors
3 rotary potentiometers for positon feedback
3 TECO Easy Drive E2-202-H1F 1,5KW p/st

1 Velleman K8061 interface for motion control

Those motor controllers look decent ego.
No, not at all, can you expand on this? I found this AC motor controller kit in a quick google search, not too many specs but it seems to be alright for the price.

Can you program the K8061 to work with the encoders? It seems like using pots or hall sensors with the analog inputs is very easy.

The biggest flaw is definitely, that it does not allow to reverse direction.
Reversing direction requires frequency inverters, not speed controllers for vacuum cleaners

However, I am not an expert on those frequency inverters.
I dont know if there are any quality differences comparing to other frequency inverters regarding reverse current protection.

@Kermit
You should check this issue with someone that uses a similar setup (Riton, scottlolo89) or with knowledge about the subject before ordering inverters.
I guess the supplier of those inverters will be able to tell you as well, if they are suitable for the simulator you are going to build.

Hi Henk
Egoexpress is wright, it´s best to call indumex ,they give good advice.
I think you need a smartdrive .
regards Ad

Hi, Thanks for the reply,
I already mailed scottlolo89 for more info, but no reply yet.
I will read all the info, hope to sort things out.
Its the weight I`m struggling with , because off the fuselage itself I need bigger motors therefore specilized system.
I will build a 24 volt system until I have enough info to go a step further
regards

Have you thought about using DC motors, 48V or more?

Hi Yes I have ,
but for the weight aproxx 3-350 kg or 800 lbs and unbalanced loads,
I opt for std 220 volt 1 ph 1 kw motors and gearboxes .
I can buy them from my work but I struggling for finding the right plc-card and motorcontrollers/frequency inverters.
If needed I could swap motors but don`t want to make to much mistakes, they are very costly

And how about Triacs controlled by an microcontroller (via optocoupler)? Traics like this: http://www.voelkner.de/products/82751/T ... del=Q62900

230V/15A/3500W - 10€

A triac is only a triac. It's like a transistor, won't control anything, it needs to be controlled to deliver power.

kermit, you have a huge project that requires special measures. Try to look for a phase inverter / AC motor controller that will take TTL input, preferably pwm or something simple. If you have that, I will help you out with the microcontroller part of it. I will be asking my professors in school about what you'll need and what is the best option.

@Frakk
As DC motors with enough torque to move a fuselage including driver draw too much amps, he absolutely right to use AC motors.

@Jakob
Kermit asked explicitly for a ready built up solution. Besides that, AC powered circuits are dangerous. I would not recommend a layman in electronics to tinker arround with AC circuits.
Besides that, your TRIAC solution, like the speed controller Frakk suggested before, is just able to turn the motor in one direction.

@Frakk and Jakob
The least Kermit needs right know is more confusion. I cannot see where you both have the experience with XSim or simulators, that would would put you in the position to make such suggestions to newbies.
We appreciate any hints to improve our DIY solutions. But please do not confuse newbies.

You should give Indumex a call, and ask if the TECO phase invertes I recommended, from the website Adgun linked, are sufficient for the use in applications, where reverse currents are an issue (due to fast motor direction changes with high payload).
The Velleman K8061 motion controller card I suggested works with XSim and it is tested. Riton and Scottlolo89 are using the smaller version K8055, as they are just using 2 motors.

Here is the english manual of the TECO E2 series inverter:
http://www.teco.com.tw/sa/file/teco_pro ... %29V10.pdf

According to the english manual (page 46,47), the inverter has overload-shutdown protection including error code display.
At least overload during motor reversing will not damage the inverter nor the motor.
As well the braking time before motor direction reverse is adjustable, if needed.

ego, I do not intend to confuse anyone, I am just trying to exploit solutions that may work or may not.
I am sorry if I confused you kermit.

I don't know if cost is an issue or not, but PLC's are not the cheapest. I work with them in school every week, and I work with electronics every day. As I said, I will ask around those who worked with a wide range of PLC's and other industrial equipment.

I guess the term PLC was Kermit' way to say, that he does not want to solder anything (which I wouldnt recommend anyway, when dealing with AC circuits).
However, fortunatly PLC is not needed at all. It would make it just more complex, as proper programcode would have to be written, and would add unneccessary costs.
That's why I proposed him to use the Velleman K8061 as motion controller. It is cheap, prebuilt, suppported by XSim and ready to connect to an inverter.

When using AC motors, yet there is no other (safe) way than to use comercial frequency/phase inverters.
