Well Tempered classic electrical data

Well Tempered Classic Electrical Data Motor I have recently a W.T. Classic, I noticed that it has an R-C-R network on the power line (600Ohm-1UF-600OHM). Deduct both to reduce the 220 (EU) tension to 110 (USA) being an American product. The engine I only know that it is a 24 synchronous pole but tension? Power? I can't find the exact electrical features, someone helps? Thanks G.Pietro
