What is the Sign of Induced Voltage in Each Rotor Segment?

Click For Summary
SUMMARY

The discussion centers on understanding the signs of induced voltage in rotor segments, specifically referencing equation 4-19 from a textbook. Participants express confusion regarding why the expression (vxB)•l does not equate to eab. The need for clearer visual representations of the equations is emphasized, with suggestions for the original poster to type out the equations for better clarity.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with vector cross product notation
  • Knowledge of rotor dynamics in electrical engineering
  • Proficiency in interpreting mathematical equations related to induced voltage
NEXT STEPS
  • Review the derivation of equation 4-19 in the relevant textbook
  • Study the implications of the vector cross product in electromagnetic contexts
  • Explore the relationship between induced voltage and rotor segment orientation
  • Learn about the application of Faraday's Law in practical scenarios
USEFUL FOR

Students and professionals in electrical engineering, particularly those focusing on electromagnetic theory and rotor dynamics, will benefit from this discussion.

Homework Statement


I want to know the minus/plus sign of induced voltage of each rotor segment. Like in file no.3, equation 4-19, why (vxB)•l is not equal to eab instead?

Homework Equations


equation 4-19 and 1-45

The Attempt at a Solution


I was searching on this book, but found nothing.[/B]

Thank You

Can you type this out? Your pictures are hard to see.
 
Thread closed. @BlackMelon, I agree with the previous poster that the images are too unclear to read. Please start a new thread, with equation 4-19 typed out.
