Welcome. I downloaded a manual for the 290 and it looks like it would be a clam shell type controller. I'm wondering if https://www.youtube.com/watch?v=-wqaX2ydJ08 or https://www.youtube.com/watch?v=9uJ0prqbmwg would help.
We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at https://www.quiltingboard.com/attach...020-01-17-.pdf
Don't forget to scroll over to the far right to find and click on the "Upload" button.
I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

Some additional info regarding reducing images at post #4 and images for the scroll and upload button can be found at #5 of quilt block ID?

He gave me an answer,but the model of sewing motor controller,is different from the one which I have ,as you can see in the picture the model is electronic M.C.P.K CAT CR513.
I would like to know how it works and I would like to have the schematic of this sewing controller,and how can I check it is running well with a multimeter?

I have never seen a manual for a speed/foot controller. I do not know how to check with a multi-meter. I see you are in Algeria, so your voltage is different. I did a search for the Cat Number "CR513" and came up with several references on ebay such as https://www.ebay.com/itm/TESTED-Vint...-/154267825430. If they have a back side view, it will show a Singer controller with the same Amps and much of the same Part Number. I have had John switch out controllers if the cord and plug were correct for the sewing machine. That is an unusual plug (from what I have seen) and it appears that the when I have searched for the Part number or Cat number they all come up with the same plug.
I noticed in your picture that there are metal pieces/rods that I'm not familiar with. It appears that yours has a chain that is attached to the bottom of the controller with a screw. It also looks like there is a metal rod on the top side, that I haven't seen anything similar to.
Some of the controllers I have seen have screws under the rubber pads, that need to be removed to disassemble the controller.
Sorry I couldn't be more help.

The controller is not a motor nor does it contain one. It is an electrical device that controls the sewing machine motor. The ones I've worked on have a system that modulates/controls the amount of electricity that the motor gets, therefore controlling the speed of the sewing machine motor. As you press your foot on the controller, the insides become closer together and more electricity flows through the device. The older American ones are basically the same on the inside.
If your controller is like the American ones, you can adjust the insides to sew a little faster, slower or just allow more variation in speed. You can replace it with an electronic controller, if you don't want to mess with adjusting the one you have.

Thank you my friends for your help,
the voltage in our countrycount220 volts,the electrical cord connected to the sewing has 5 pins,there is an Y symbol on it.i think this model is not exactly as the american ones.there is a metal bar going through a white device, and there is also a spring that I can not find its location
