- 論文の詳細を見る
In a DC motor, arcing occurs during commutation, which causes wear of commutator and brush. This is often one of practical problems in the DC motor. To evaluate the wear of commutator and brush mechanical wear and arc erosion have to be separated respectively. For this purpose a switching device system is developed and the arc discharge almost equivalent to the commutation arc is realized. Using this system the mass change of carbon contacts is examined in air, gasoline and ethanol to evaluate the arc erosion of commutator and brush.
