SUMMARY

A high RPM alternator design requires careful consideration of power requirements based on load and parasitic losses. The discussion highlights the need to calculate horsepower (HP) necessary to drive the alternator, factoring in its weight and operational speeds between 10,000 to 15,000 RPM. Utilizing a standard three-phase alternator design is suggested for high RPM applications, emphasizing the importance of specific calculations for efficiency and performance.

PREREQUISITES
  • Understanding of electrical engineering principles
  • Familiarity with three-phase alternator design
  • Knowledge of power calculations, including parasitic losses
  • Basic mechanics related to rotational dynamics
NEXT STEPS
  • Research how to calculate horsepower for high RPM applications
  • Learn about three-phase alternator configurations and their efficiencies
  • Investigate methods to minimize parasitic losses in alternators
  • Explore materials and designs that reduce weight in high RPM alternators
USEFUL FOR

Engineers, automotive designers, and hobbyists interested in high-performance alternator design and optimization for high RPM applications.

And how would I do all the math for how much HP I would need to turn it based on its weight etc.?

Would I just use a normal 3 wave alt for high RPMs? Like roughly... 10-15000rpms

How about asking more specific questions in regard to designs?

The power required will be a function of the loads applied. How much power are you expecting from it? The power input will have to be at least that plus parasitic loads like friction and rotor windage.
