Looking for some clarification....
I recently had a discussion involving motor surface temps.
I am under the impression that an inverter duty rated motor (per MG1 part 31) would not necessarily run cooler as far as surface temperature is concerned when compared to a non inverter duty rated...
Does anyone have any feedback on the use of Transient Voltage Surge Suppressors and their effectiveness for preventing damage to VFDs due to lightning strikes and/or power surges?
I think the reasoning behind using a part winding start motor in this particular application is that it was what was available on short notice for the particular frame size needed. I haven't been able to find much information on part winding start motors other than the basic terminal...
Can a 3-phase, 460v, 6 lead motor wound for a part winding start be started across the line by tying together leads 1&7, 2&8, 3&9?? Even if possible, is this a good practice??
