| Abstract(in English) | A small DC motor is widely used to drive an automotive fuel pump. Generally, the motor is put in the gasoline tank, so the coil current is commutated between the brush and the commutation segment in gasoline. But recently, the car fuel has been changed gradually from the gasoline to the ethanol due to the environmental consideration and the price rise of the gasoline. In this report, the fundamental characteristics of the commutation are investigated with the carbon flat commutator in ethanol 50%/gasoline 50%. The long-time experiment shows that the arc duration and commutation period in this fuel are in good agreement with the tendency of damaged part of the brush and commutator. And the experiment results of the brush wear shows that wear per the arc energy decreases with commutation current increase. |
