[ Problem Point ]
A pole crosses between the commutator fragment of rotter, time, it was in trouble about degradation early stage of a interlayer insulation thing by impulse wave discharge.
[ Kaizen Point ]
Insulated protection was carried out on the Toughtape. Reliability improved by the sufficient insulation and radiation resistance of PEEK resin.
