Abstract: Attempts are being made to elucidate the production mechanism of commutation spark produced on universal motor from the surface of images, by using a high-speed camera. Last time, we reported at what position of the brush that the commutation spark during an AC operation is liable to be produced. This time, we took pictures during a DC operation, and compared them with those taken during an AC operation. As a result, it has become clear that, although commutation spark is liable to be produced on the left side in both AC and DC operation, this production of commutation spark is liable to take place at a position further to the left during a DC operation.
