Exploring the Potential of Vertically Stacked Permanent Magnet Alternators

In summary, the conversation discusses a permanent magnet alternator with an axial flux configuration that uses vertically stacked stators and rotors. This configuration requires half the number of magnets compared to the traditional fabrication method. The question is raised whether the vertically stacked PMA can produce the same current and voltage output as a traditional PMA at the same RPM, given that both are fabricated with the same coils and air gap but different magnet counts. The individual also created a visual aid to demonstrate their understanding of the lines of flux in this configuration.

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.

What is a permanent magnet alternator?

A permanent magnet alternator is an electromechanical device that converts mechanical energy into electrical energy. It uses permanent magnets to create a magnetic field and induce an alternating current (AC) in a wire coil. This type of alternator is commonly used in small-scale power generation systems, such as wind turbines and small engines.

How does a permanent magnet alternator work?

A permanent magnet alternator works by rotating a shaft, which turns a set of magnets inside the alternator. As the magnets rotate, they create a magnetic field that cuts through the wire coils, inducing an AC current. The amount of current produced depends on the speed of rotation and the strength of the magnets.

What are the advantages of a permanent magnet alternator?

One of the main advantages of a permanent magnet alternator is its simplicity. It has fewer moving parts compared to other types of alternators, making it more reliable and easier to maintain. It also has a higher power-to-weight ratio and can produce electricity at lower speeds, making it suitable for small-scale power generation.

What are the applications of a permanent magnet alternator?

Permanent magnet alternators are commonly used in small-scale renewable energy systems, such as wind turbines, hydro turbines, and micro-hydro systems. They are also used in small engines, such as those found in motorcycles and scooters, to charge the battery and power the electrical systems.

Can a permanent magnet alternator be used as a generator?

Yes, a permanent magnet alternator can be used as a generator. In fact, it is its primary function. As long as the alternator is rotated at a sufficient speed, it will produce electricity. This makes it a versatile and reliable source of electricity in various applications.
