Here are some of the advantages of 5 or more rotor axial flux machines:
Higher power density: 5 or more rotor axial flux machines can have a power density of up to 50 kW/kg, which is significantly higher than traditional axial flux motors. This makes them ideal for applications where space and weight are at a premium, such as electric vehicles and aerospace.
Better cooling: 5 or more rotor axial flux machines have a better cooling surface area than traditional axial flux motors. This means that they can generate more torque without overheating.
More compact and lightweight design: 5 or more rotor axial flux machines are more compact and lightweight than traditional axial flux motors. This is because they do not require a large iron core.
Increased scalability: 5 or more rotor axial flux machines can be easily scaled up or down by adding or removing rotors. This makes them suitable for a wide range of applications.
In addition to these advantages, 5 or more rotor axial flux machines are also expected to be more cost-effective to manufacture than traditional axial flux motors. This is because they use less iron and copper.
Potential applications
5 or more rotor axial flux machines have the potential to be used in a wide range of applications, including:
Electric vehicles
Aerospace
Industrial automation
Robotics
Marine applications
Renewable energy generation
Challenges
One of the key challenges facing the development of 5 or more rotor axial flux machines is the need to optimize the design for the target application. For example, a 5-rotor axial flux motor designed for use in an electric vehicle will have different requirements than a 5-rotor axial flux motor designed for use in an industrial automation application.
