The motor has always, from day one, had electrically caused vibration. It's pretty easy to tell as motor vibrates when powered up but if power is removed the vibration stops instantly. I would expect this with a single phase motor but not 3 phase. Eric |

No, seriously. Its just tracing circuitry. Or are you scared of the fire marshall bill image from the show "In Living Color" (that showed from 1990-2006) where them and electricians have spiked hair and are accidentally shocked or burned every day. Gimmie a break. |
