SUMMARY

Using a motor-powered generator with a speed multiplier gearbox does not increase electrical output due to the principle of conservation of energy. The discussion confirms that any potential gains from the gearbox are negated by inherent losses, making it impossible to produce more power than the input. The consensus is that the efficiency losses in the gearbox would prevent any increase in electrical output.

PREREQUISITES
  • Understanding of the conservation of energy principle
  • Knowledge of gearbox mechanics and efficiency losses
  • Familiarity with electric motor and generator operation
  • Basic concepts of power generation and output measurement
NEXT STEPS
  • Research the efficiency of different types of gearboxes in power transmission
  • Explore electric motor and generator design for optimal performance
  • Investigate alternative methods for increasing electrical output
  • Learn about energy loss calculations in mechanical systems
USEFUL FOR

Engineers, electrical technicians, and anyone involved in power generation or mechanical design seeking to understand the limitations of motor-powered generators.

Hello everyone,

I would like to know if it is possible to produce more electrical power from a generator if it is powered by an electric motor through a speed multiplier gearbox? Any answer will be greatly appreciated.

More power than what?
 
Short answer: no. That would violate conservation of energy. The gear box losses alone would prevent that from working.
