Exploring the Potential of Vertically Stacked Permanent Magnet Alternators

Click For Summary
SUMMARY

The discussion focuses on the performance of vertically stacked Permanent Magnet Alternators (PMAs) in an axial flux configuration. The key finding is that this innovative design requires only half the number of magnets compared to traditional PMAs while maintaining the same coils and air gap. Participants inquire whether the vertically stacked PMA can achieve equivalent current and voltage output at the same RPM as its traditional counterpart. Visual aids were created to illustrate the expected magnetic flux lines in this configuration.

PREREQUISITES
  • Understanding of Permanent Magnet Alternators (PMAs)

Greetings, I have been working on a permanent magnet alternator, axial flux configuration.
It has been configured with vertically staked stators and rotors. The traditional fabrication technique the stator is one large diameter with a large diameter magnet rotor above and the below the stator.
The vertical configuration that I am use requires ½ the magnets then the traditional fabrication method.

1 Can the vertically stacked PMA produce the same current and voltage output as a traditional PMA at the same RPM? Both are fabricated with the same coils and have the same air gap. The PMA’s are fabricated with same magnets, the only differences are the vertically stacked configuration has ½ the magnet count.

Greetings, I had some time to create a visual aid of would I believe the lines of flux may look like when the rotors and stators are stacked vertically.
Comments welcome.
