The quality of our repair meets or exceeds ANSI/EASA Standard AR100-2015.

  • We dismantle, steam-clean and sand-blast the components.

  • We test each component to determine the necessary repair(s).

  • All motors are wound to Class H specification using inverter duty wire.

  • All windings are vacuum pressure impregnated (VPI) using class H varnish.

  • Slot liners and phase insulation are Nomex.

  • All sleeving used for jumpers and connections can withstand a 2000 volt surge.

  • We tension-band armatures with Permafil-treated glass banding to hold the coils in place.

  • We turn, dynamically balance and undercut the armatures to the proper depth to extend the operating life of the motor, to prevent premature shorts and to increase brush life.

  • All motors are continuous-wound without weld connections on jumpers.

  • We only use the highest quality bearings.

  • Motors are tested with 2500 volts to ground.

  • Amperage and resistance are measured in every phase individually.
