NOS Motors: all the motors are subject to accurate inspection and cleaning, with complete disassembling of each single mechanical and electric part and replacement of worn or dead parts if necessary.
New production motors: We use rotating stator oversized synchronous motors (external), therefore of very high precision and stability, additionally improved with ultra-silent bearings with polyamide cages.
The motor/condenser coupling is carried out using the stethoscope, in fact, the phase shifter capacitor must be absolutely precise, and therefore, many must be tested until the complete absence of noise and vibrations is achieved.
