Electric motor load vs efficiency historical background

Click For Summary
SUMMARY

The discussion centers on the relationship between electric motor load and efficiency, specifically noting that efficiency increases with load, peaking at approximately 75% of the rated load. This phenomenon is described by the square root function, indicating a mathematical basis for the efficiency curve. The inquiry seeks to identify a physicist who documented this relationship and the theoretical framework behind it, although no specific names or theories were provided in the discussion.

PREREQUISITES
  • Understanding of electric motor operation and efficiency metrics
  • Familiarity with the square root function in mathematical modeling
  • Knowledge of historical theories related to electrical engineering
  • Basic principles of physics related to load and performance
NEXT STEPS
  • Research the historical development of electric motor efficiency theories
  • Explore the mathematical modeling of load vs efficiency in electric motors
  • Investigate the contributions of key physicists in electrical engineering
  • Study the implications of operating electric motors at different load levels
USEFUL FOR

Electrical engineers, physicists, and students studying motor efficiency and performance optimization will benefit from this discussion.

Is there a physicist who has discovered this, and could you explain how he/she did it?
I was trying to find it on the internet, but it only gives me a lab review of load vs efficiency.

thank you

What I am trying to say is that:
when you increase the load of the electric motor the efficiency goes up (it creates this sqr(x) function, so the maximum efficiency is around 75% of rated load). But my question is this:
Was there a physicist who have observed this phenomena and described it if this is the case then what was his name and how he did this? or is this based on a theory; therefore, people knew this from the beginning of the creation of this particular theory, and if this is the case then what is the name of the theory, and how he came up with this theory?
 
nevermind about this question
