I repeat my question because of misunderstandings.
I have one 3-phase motor of SIEMENS designed for the following parameters:
50Hz/500V/0,75kW/1,92A/2855rpm///575V/60Hz/0,86kW/1,96A/3455rpm
The same motor can work either with 500V/50Hz or 575V/60Hz
But in the reality I have rated voltages in...
What will be the difference in current flow, speed and power if I connect 3~motor to mains 400V/50V or to mains 480V/60Hz. In which case will be the current and power bigger? Will be the speed different?
3~Motor data are as follows:
50Hz/ 500V/ 0,75kW/ 1,92A/ 2855/min
60Hz/ 575V/ 0,86kW/ 1,96A/...
What is rated 1-phase and 3-phase power distribution (rms or peak-to-peak) in The USA? What are basic formulas for its calculastion or where to find them?
What are the advantages or disadvantages of 480V/60Hz three-phase power distribution in the USA in comparison to 400V/50Hz in Europe? Why 208V/120V? How to calculate 208V?
