The voltage imbalance will cause current imbalance. Current imbalance can (and will) cause additional noise. The much larger problem is heat. Trying to correct with a buck-boost xfmr will be like trying to catch a falling ball of Jello. You will never be able to get things right since the...
Dimensions are defined in National Electrical Manufacturer's Association (NEMA) Standard MG-1. Any motor manufacturer can provide you this kind of data. Some of the dimensions can be determined from the motor frame number. Example: For a foot-mounted motor the dimension from the floor to the...
Some old information I have notes that NEMA SG.2-46-10 (not sure if standard is current but explanation would still applicable) states that the fuse will melt in a range of 15 to 35 seconds at a current value equal to 100 * "R" number of the fuse. As such, you need to get the proper...
In the best of conditions with linear loads , most manufacturers of 3-phase transformers (both dry & liquid-filled) recommend limiting single phase load on the single-phase leg to only 5% of the total xfmr kva due to circulating currents and additinal xfmr heating. This really minimizes...
