How Did WEG Achieve IE4 Efficiency with Aluminum Rotor Cages?

AI Thread Summary
WEG has achieved an IE4 efficiency rating for their motors using aluminum rotor cages, likely through proprietary methods that may involve trade secrets. The discussion suggests that increasing the amount of iron and using larger conductors could be key factors in reducing efficiency losses. Some participants recommend consulting WEG directly or reviewing specific technical articles for deeper insights. There is speculation about the competitive nature of the information, indicating that WEG may not disclose their methods easily. Overall, the conversation highlights the complexities of achieving high efficiency in electric motors while using aluminum materials.

:welcome:

That sounds like a question you should ask WEG. Or are you WEG's competitor? :wink:
 
They will not answer it :P
 
Well then it sounds likely that they have a trade secret that they don't want others to know. :sorry:
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
