Abstract: In the present paper, we report results about the preparation and
the morphological, thermal, mechanical and electrical characterization of new
materials for the impregnation of rotor and stator windings of medium power
traction motors. These new materials are obtained by the addition of nano-sized
alumina (Al_{2}O_{3}) fillers to
commercially available silicone resin. Their measured physical properties are
compared with those of the unfilled matrix, used as a reference, and the
influence of the weight concentrations, ranging between 1 wt % and 7 wt %
is fully discussed.
