Axial Flux Electric Motor

An axial flux motor also known as an axial gap motor or pancake motor is a geometry of motor construction where the gap between the rotor and stator and therefore the direction of magnetic flux between the two is aligned parallel with the axis of rotation rather than radially as with the concentric cylindrical geometry of the more common radial gap motor.

The coil overhang in a traditional radial flux motor is not beneficial for its functioning left. While the vast majority of electric motors currently in circulation are radial flux designs magnax claims the key to the high power density it s achieving is the direct drive axial flux design. The axial flux motor from his tests later went into production in the emrax motor line with four different size motors available. This translates to higher efficiency.

Cooling in case of radial flux machines the heat has to be transported through the stator to the outside of the machine. Since then a british company yasa has begun production of axial flux motors aimed at the ev market. Axial flux motors on the other hand offer the lowest possible copper loss. In other words more of the battery power gets turned into useful motor power.

Evo axial flux electric motors have one of the highest usable power and torque densities of any electric vehicle drive motor available on the market today. At the right the concentrated windings of the magnax axial flux motor. Because of this they are suitable for a range of high performance drivetrain applications.
