Axial flux generator dual rotor question

M. (2011). Axial Flux Alternator. In summary, the conversation discusses the construction and calculations of an axial flux generator and the question of how many magnet pole pairs are present in the design. It is determined that there are six pole pairs since each time a coil sees a flux change, it requires a pair. Therefore, with 24 magnets in total, there are six pairs.

I am building an axial flux generator with dual rotor and single stator. I was doing calculations and have a magnet pole pair question i need help with, there are 12 magnets on each rotor with North pole on one rotor across from South pole on the other rotor.

Since there are 24 total magnets positioned in a way for the flux to travel from a North pole, through the stator and into a South pole, is this consider one pole pair?

Or do the North and South magnets have to be on the same rotor to count as a pair?

Are there six pole pairs or are there 12 pole pairs?

The axial flux alternator is a simple three-phase alternator. Each time a coil sees a flux change (North to South) requires a "Pair". So, 12 positions (24 magnets in your case) is six pairs.

1. What is an axial flux generator dual rotor?

An axial flux generator dual rotor is a type of electric generator that uses two parallel rotors to generate electricity. These rotors are typically mounted on a common shaft and rotate in opposite directions, producing a stronger and more stable magnetic field.

2. How does an axial flux generator dual rotor work?

An axial flux generator dual rotor works by using the interaction between the rotors and stator to generate electricity. The rotors are made up of permanent magnets, while the stator contains the coils of wire. As the rotors rotate, the changing magnetic field induces an electric current in the stator, which can then be used to power electrical devices.

3. What are the benefits of using an axial flux generator dual rotor?

There are several benefits to using an axial flux generator dual rotor. These include increased efficiency, better power output, and lower maintenance costs. The design also allows for a more compact and lightweight generator, making it suitable for a variety of applications.

4. What are the applications of an axial flux generator dual rotor?

An axial flux generator dual rotor can be used in a wide range of applications, including wind turbines, hydroelectric generators, and even in hybrid or electric vehicles. It is also commonly used in off-grid or remote power systems, where a reliable and efficient source of electricity is needed.

5. Are there any limitations to using an axial flux generator dual rotor?

One potential limitation of using an axial flux generator dual rotor is the higher initial cost compared to traditional generators. Additionally, the design may not be suitable for all types of power generation, such as large-scale industrial applications. However, advancements in technology are continually improving the efficiency and cost-effectiveness of this type of generator.
