含浸刷子の動作特性と処理条件との関係

Generally, the brush with excellent Commutating ability is made of large graphite particles. Therefore mechanical strength is poor, so the brush life is short.
Under the high current densities, the particles fall away from the sliding surfare of the brush and then commutation goes bad.
For the purpose of improviny this defect, the writter studied the impregnate brush with synthetic resin.
In conclusion, the brush, applying Hita buran resin denaturated by phenol has been more improved on the character of the life, friction, and commutation than ordinary hrush in common use.
