Axial vs Radial Flux Motors

• Compare specs - 10+ kW/kg vs 3 kW/kg - https://insideevs.com/news/361185/magnax-axial-flux-electric-motor/
• There are 2 new types of axial flux motors - electrostatic and yokeless - [1]
• Axial flux motor is attractive compared to radial flux when pole number is high and air gap is low. -[2]
• Basics of axial gap motors - With strong magnets, we don't need iron. High torque in axial flux motors is achieved by using a larger diameter. [3]
• Axial flux is the new kid on the block - [4]
• Paper shows that Axial flux motors are about 4% more efficient than radial flux - [5]
• Axial flux motors appear to compete with Tesla cars' electric motor performance - [6]
• Indiegogo explains segmented axial flux motor - [7]

Summary: Axial flux is the future for higher efficiency, and power density.
