European motor tricks?
European motor tricks?
(OP)
We have a couple of examples at our company of European OEMs who purposely wire motors for the lower voltage (277) and yet run them at the higher voltage (480). I have talked with a European tech who once told me that there was some trick like this that they did to get more power out of a motor. Does anyone here know the logic behind this?
Thanks
Thanks





RE: European motor tricks?
This is sometimes being used when you have a VFD. By connecting for the lower nominal voltage and running them at a frequency that is 480/277 times nominal frequency and at 480 V, you get same torque at higher speed. And, presto! More power out of that motor.
