SUMMARY

This discussion focuses on the design and selection of an electric generator and control system for a project involving power generation from a moving fluid. The project requires a generator capable of handling variable torque output, estimated between 6 Nm and 3.5 Nm, with a power output of 200-300 W. The user seeks advice on implementing closed-loop circuit control to manage varying loads effectively. The voltage output can be either DC or AC, depending on the most suitable solution for the application.

PREREQUISITES
  • Understanding of electric generator types and specifications
  • Knowledge of closed-loop control systems
  • Familiarity with torque and power calculations
  • Basic principles of AC and DC voltage systems
NEXT STEPS
  • Research closed-loop control systems for electric generators
  • Explore the design of variable torque electric generators
  • Investigate the differences between AC and DC generator applications
  • Learn about power management techniques for low-output generators
USEFUL FOR

Engineering students, electrical engineers, and professionals involved in power generation and control system design will benefit from this discussion.

Hi All,

This is my first post on here and hopefully there will be a successful outcome!

I am a final year engineering student and am working on a design project relating to power generation from a moving fluid.

I am seeking help in the design/selection of an electric generator/control system. I am wondering if it is possible to have closed loop circuit control on a generator to induce varying load control on the generator. The fluid source is of varying pressure resulting in a variable torque output. Power output is not overly large, 200-300 W. Torque is estimated to start at about 6 Nm, and decrease to about 3.5 Nm over a 1 minute period.

I am really open minded to the electrical side of things, just want to know what you think the best solution is. Voltage can be DC or AC, whichever you feel is best.

Thank you, and I hope some success will arise from this!

Dave

Are you looking for a way to control the voltage output from the generator? I'm not 100% sure of your question.
 
Control current, voltage ideally remains constant
