Does this problem exist?

Suppose a pump is equipped with a motor of 15 kilowatts; if I conduct experiments using a 75-kilowatt motor, will the resulting current and power values be higher or remain the same compared to those of the 15-kilowatt motor? If it’s high, then is there any proportional relationship?
Theoretically, with constant power, the current should be higher; a 15kW motor should be more efficient than a 7.5kW motor. There is no proportional relationship
It’s probably high; it’s difficult to calculate the exact value. The no-load current of a 75KW motor is higher than that of a 15KW motor under load, so it’s easy to understand why
Yes, I think the same way. It would be best if some expert could provide a ratio; even an approximate one will do
I’ll give it a try again and share the results with everyone
You can first run the 75kw and 15kw motors on no-load, recording their no-load current and power for each motor. After that, you can conduct tests with the pumps attached, allowing for a comparison to be made.
I found two level-4 motors, with capacities of 5.5 and 15 respectively. It can be seen that there is a significant difference in terms of electrical parameters. Share it
