Vertically stacked Stators and Rotors Permanent Magnet Alternator

In summary, the conversation discusses the design and testing of a PMA using vertically stacked stators and rotors. The use of flux lines from both ends of the magnet and parallel connection of stators results in increased output at lower RPMs and fewer magnets compared to dual rotor designs. The data collected at different RPMs can be used to predict output at higher RPMs using online calculators for PM motors.

Greetings, I fabricated a PMA using vertically stacked stators and rotors. I tested the unit on a lathe and was able to gather the following data at different RPMs. The design uses the flux lines from both ends of the magnet. This configuration allows the stators and rotors to be stacked vertically. The stators are connected in parallel so the internal resistance drops, output increases at lower RPMs as more stators and rotors are added. The configuration uses less magnets than dual rotor designs with fixed internal resistance. Is there a mathematical solution to predict output at a higher RPMs using the data that I have been able gather?1 Stator ,
Amps , RPM, Internal resistance
0.38 , 190, 4.3 ohms
2.06 , 310
3.8 , 440
2 Stators
0.51 , 189 , 2.4 ohms
2.06 , 310

2.95 , 270

1. What is a Vertically Stacked Stators and Rotors Permanent Magnet Alternator?

A vertically stacked stators and rotors permanent magnet alternator is a type of generator that uses permanent magnets to convert mechanical energy into electrical energy. The stators and rotors are arranged in a vertical orientation, with the stators surrounding the rotors, in order to increase the efficiency and power output of the alternator.

2. How does a Vertically Stacked Stators and Rotors Permanent Magnet Alternator work?

A vertically stacked stators and rotors permanent magnet alternator works by using the interaction between the permanent magnets on the rotors and the stators to produce an electromagnetic field. This field induces an electrical current in the stators, which can then be used as a source of power.

3. What are the advantages of using a Vertically Stacked Stators and Rotors Permanent Magnet Alternator?

The advantages of using a vertically stacked stators and rotors permanent magnet alternator include increased efficiency, higher power output, and a more compact design compared to traditional alternators. Additionally, the use of permanent magnets reduces the need for maintenance and makes the alternator more reliable.

4. What are the applications of a Vertically Stacked Stators and Rotors Permanent Magnet Alternator?

A vertically stacked stators and rotors permanent magnet alternator can be used in a variety of applications, including wind turbines, hydroelectric power plants, and other renewable energy systems. It can also be used in vehicles, such as electric cars and hybrid vehicles, to generate electricity.

5. How do I choose the right Vertically Stacked Stators and Rotors Permanent Magnet Alternator for my needs?

When choosing a vertically stacked stators and rotors permanent magnet alternator, consider factors such as power output, efficiency, and compatibility with your power source. It is also important to consider the size and weight of the alternator, as well as any additional features that may be necessary for your specific application.
