Pulsed voltage surge resistant magnet wire

A pulsed voltage surge resistant magnet wire comprising a conductor, a continuous and concentric and flexible uniform coat of base insulation material superimposed on said conductor, and an essentially continuous and concentric and uniform pulsed voltage surge shield overlaying said coat, said shield having therein a binder and an effective amount of particulate material to protect said coat and binder from pulsed voltage surge failure, said shield being superimposed on said coat, said particulate of said shield being from about 0.005 microns to about 1 micron in size, and a continuous and concentric and flexible and uniform top coat of insulation material superimposed on said shield, said conductor and said coats and shield being in compliance with ANSI/NEMA MW 1000 1993.

A magnet wire comprising a conductor, a continuous and concentric and flexible uniform coat of base insulation material superimposed on said conductor, an essentially continuous and concentric and uniform PWM, variable frequency and/or inverter motor drive pulsed voltage surge shield superimposed on said coat, said shield comprising a continuous, concentric and essentially uniform layer of particulate material and binder overlaying said coat of insulation material, said shield having from about 1% to about 65% by weight of said particulate material uniformly dispersed throughout said binder, and a continuous and concentric and flexible and uniform top coat of insulation material superimposed on said shield, said conductor and said coats and shield being in compliance with ANSI/NEMA MW 1000 1993.
