Understanding Axial Flux Motors
At the heart of revolutionary electric motor design lies the first axial flux motor, dating back to the 1830s. Pioneered by none other than Nikola Tesla, this ingenious technology.
In principle the axial flux motor is the same as the radial flux motor but with inherent topology differences. The magnets and winding are placed axially on the disk of the rotor and stator such that the flux path is always parallel to the shaft unlike its counterpart radial flux motor where the flux direction is perpendicular to the rotating shaft.
Thus because of its topology, we can place the rotor and stator in a disc form due to which less space is required overall giving it less form factor than conventional radial flux motors which are heavy and bulky in size.
Today, axial flux motors are celebrated for their ability to deliver higher power density and efficiency, making them the preferred choice in applications where space and performance are critical.
