Axial geometries allow some magnetic topologies that would not be practical in a radial geometry. Even within the same electrical operating principle, different application and design considerations can make one geometry more suitable than the other. brushed DC, induction, stepper, reluctance) that can be used in a radial motor. Īlthough this geometry has been used since the first electromagnetic motors were developed, its usage was rare until the widespread availability of strong permanent magnets and the development of brushless DC motors, which could better exploit this geometry's advantages.Īxial geometry can be applied to almost any operating principle (e.g. The rotor shown to the right is magnetized axially with alternating polarity.Īn axial flux motor (also known as an axial gap motor, or pancake motor) is a geometry of electric 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.
