Engine speed regulator plate CVA 218 BITRON.

Hi friends ... I am doing a motor mount of washing machine brushes and I have fed it through the electronic plate CVA218 BITRON, I have googleado and it turns out that this plate, have installed the washing machines Whirpool or Indesit. My question is if you know where I can insert a speed regulator potentiometer in the plate to be able to regulate its speed of rotation. Its value and its connection in the plate. This plate is prepared with some bridges to select the spin control or not, if it is carried by the machine in which it is installed. Attached is a diagram I found on the internet, not completely the same, but basically yes. In case any of you have knowledge of an indesit model that has a pot so installed and that remembers where it was connected on the plate. Thank you very much. Note that as you close the switches in Diagrams 2, 3, 4, 5, 6, 7, or 8, you do the following: -If I close 4, the engine will spin about 100 rpm. -If I close 3 it does nothing. -If I close the 5, it starts spinning at about 100 rpm and then it goes up to 600 rpm. -If I close 6, it starts spinning at about 100 rpm and then jumps at 1000 rpm. -If I close the 8 turns at about 50 rpm. If you observe the first photo that I upload of components, you will see to the right it has tabs of PCB to cut out by the holes in the plate, where it says "B" and in another, "REG CENT" that means that according to the functions of the machine where the plate is installed we will have to cut these squares or tabs of the card. The plate that I own is the same as the first photo. However, in the third photo you can see that there are other configuration tabs broken. Greetings and thanks.

Dear, I am consulting you if you want to adapt this plate to a washing machine or if you want to use the motor for another utility. regards

Hi luis38, it is for another utility to like washing machine, is to move a car alternator and generate electric current. I need you to take tacho control so that the torque is constant and so with this plate regulates the current of the brush motor steadily despite the alternating charge of the alternator. I am building an AC generator assembly for research and learning purposes. A sinusoidal alternating current source regulated in frequency according to the speed of rotation of the driving motor.

Dear, I fully understand the idea you are trying to put into practice. Unfortunately I am not very familiar with the machines of the Indesit / Ariston Line.
I never set out to investigate how the Generating Sets compensate for revolutions by increasing consumption in order to maintain constant frequency.
Some time ago a public colleague the electronic scheme of a control module of a Ballay washing machine, which is simpler than the Indesit / Ariston.
If I find it, I'll send it for investigation. regards

Thank you Luis. This board I think is a microcontroller with speed controller of the PWM motor (Pulse, (Wide) Width, Modulated), and is controlled by the microcontroller BITRON CM04 (20 pin), in the photos appears another one different from mine, ic BITRON CM03, I have searched online but nothing, I can not get your datasheet, neither the cm04, nor the cm03. It is manufactured by ST microelectronic. Thanks and see you soon.
