STF164 Series Alternator Suppliers
The insulation system is class 'H'.
All wound components are impregnated with materials and processes designed specifically to provide the high build
required for static windings and the high mechanical strength required for rotating components.
WINDINGS & ELECTRICAL PERFORMANCE
All generator stators are wound to 2/3 pitch. This eliminates triple (3rd,9th,15th) harmonics on the voltage waveform
and is found to be the optimum design for trouble-free supply of non-linear loads. The 2/3 pitch design avoids
excessive neutral currents sometimes seen with higher winding pitches, when in parallel with the mains. A fully
connected damper winding reduces oscillations during paralleling. This winding, with the 2/3 pitch and carefully
selected pole and tooth designs, ensures very low waveform distortion.
