摘要

In recent years, use of inverter-driven induction motor in industries has continuously increased because of the demand for energy-saving, variable speed drives. However, these modern inverters introduce additional stresses into the motor's polymer insulation system. To prevent the premature motor failure, the new polymer nanocomposites, with improved resistance under pulse voltage were tried out. The properties of standard polymers and those with nanofillers were measured and compared. It was found that the nanocomposites could greatly extend the lifetime of inverter-fed motors insulation because of their excellent resistance to corona discharges and improved dielectrical, mechanical, and barrier properties.
