Why do electrical generators experience load effects?

Click For Summary

Discussion Overview

The discussion centers around the effects of loading on electrical generators, specifically why generators experience a decrease in performance or "bog down" when electricity is drawn from them. The scope includes theoretical considerations of energy conservation and practical implications for generator systems.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions why drawing electricity from a generator causes it to bog down, suggesting that the draw should make it easier for the generator to function.
  • Another participant explains that when a generator is loaded, the load current creates a torque that counters the input mechanical torque, describing this as motor action and noting that generators can also function as motors.
  • A different participant shares their upcoming work with a generator system and expresses curiosity about loading effects, indicating a belief that using multiple generators to split the load may reduce overall drag, although this remains speculative until tested.
  • One participant emphasizes that the system will always adhere to the principle of conservation of energy.

Areas of Agreement / Disagreement

Participants generally agree on the principle of conservation of energy, but there are differing views on the implications of loading on generator performance and the effectiveness of using multiple generators to manage load.

Contextual Notes

Some assumptions about the mechanics of generator operation and the specifics of load distribution remain unaddressed, and the discussion does not resolve the initial question about why generators bog down under load.

I was wondering why it is when you use the electricity from an electrical generator, it bogs the generator down? Shouldn't the draw off of electricity negate any sort of back flow there by making it easier on the generator to function?

Conservation of energy is immutable. When the generator is loaded, the load current produces a torque which counters the input mechanical torque. This is motor action. Generators are motors as well, & vice-versa.

Ty cabraham, I will soon be working a generator system and was curious about the effects of loading on generators. I had guessed that such was the case but figured it would be better to ask. Hopefully soon I will be able to set my system. From the figures is have been working with I should be in the clear on the power to crank the generators under load as I will have 5 generators to split the load. Hopefully dividing the torque between them should be such that even though it will still be the same overall amount the division will produce less drag on the whole. I am guessing anyway. I will have to wait until I get it up and running to test it out.
 
Just note that no matter what, the system will obey Conservation of Energy.
