Hi everyone . I recently purchased a tire changing machine that came with an engine that was not working. It is an elprom engine and the control board is a Fiel 1007-01 .I took the cover off the control board and discovered that one of the 4 large capacitors had burned through it's solder contacts on board.Could see black soot that was on the metal board underneath it .There was a thermistor beside it that had a small piece out of the side of it .I replaced both but still board is not working.Need some help to test /diagnose what could be wrong with this .These boards are impossible to find so replacing it seems unlikely or very expensive.It's made in France and the motor is made in Italy.From what i gather the control board input is 120 volts then converts to DC then back to 220 volts ac to the motor. This board is connected to switches that controls the 2 speeds and reverse for the motor.I am only a beginner but have a multimeter and can solder well.Any help would be great
It seems the company is gone and the original website was bought out by a Chinese lottery. There might be some useful specs on
the archive but I wouldn't expect it. More direct to resolve is to analyze the purpose and best solution. Your tire changer needs a motor and you have some sort of inverter-driven motor to convert the power source to your location. It might be more expedient to find out your requirement specs and possible solutions
Typically speed coversion was done with a motor generator to convert 240 to 120Vac 60/50Hz then with an AC=>DC=>AC inverter to motor here which allows vbl. speed.
If you are in EU with 240Vac /50Hz and you need a variable-speed ESC motor controller board, that might be easier to find.
Your local power is ?
The attached motor is motor
Single phase 120Vac
Bi-direction control? Y/N ?
Variable speed Yes 0 to 168 Hz ( *3600/N = 5040 RPM) requirements?
Inverter to DC?
Remote control input? just on off?

Motoinverter
- motor with a frequency inverter integrated into the
terminal box.
- This box remains of extremely reduced dimensions
comparing to the traditional motor terminal boxes
and it allows an easy installation even in very
reduced space.
The variable speed drive (VSD) included in the motor is a open
loop converter digitally programmed. The technologies used to
design the product and the components are based on the last
generation components like microcontrollers and IGBT for an
efficient motor drive.

Relay OK? Any live voltage tests?
