AXIAL FLUX Advantages of Multi Segment Axial Flux Motors

LEVERAGE

Axial flux machines have an inherent mechanical advantage due to leverage.

The magnets and stators are located farther away from the center shaft giving more torque for the same magnet area.

MULTIPLE ROTORS

Unlike radial flux or common axial flux machines, our machines have multiple rotors, which means more surface area for magnets and windings in a compact design. Length is only limited by practical current and voltage limitations of conductors chosen. Meaning high voltage motors can achieve incredible power by adding more rotors and more windings until the voltage exceeds winding insulation values. These values can be higher than standard axial flux motors due to our patent pending winding design with heavy electrical isolation between conductors.

FLUX PATH

Axial flux machines are inherently more efficient in the electromagnetic path. For standard radial flux machines, the magnetic flux moves from a magnet to a stator tooth, through iron in the stator, the windings, then back through another stator tooth (having made a flux U-turn) and back to another magnet, a very long path as in the diagram to the left. Axial flux machines, the flux path is much shorter, from the first magnet, through one winding and straight to another magnet. Our axial flux machines allow the magnetic "force" to pass directly from one magnet to the next in a straight path.

COOLING

Our patent(s) pending design motors inherently allow air or other cooling media to flow over the entire conductor path inside the motor. Another unique feature is the ability of any core material to be placed directly in the coolant path with surface contact to the windings pulling heat from the windings directly into the coolant or air path.

LIGHT WEIGHT

Built from high quality 6061 Aluminum our case is much lighter than the conventional steel case of radial flux motors. As of now, our patent(s) pending design motors are available in ferrite core, silicon steel, and air core (coreless) designs using the same windings. This means if low ripple, high acceleration velocities, and efficiency are a priority, then coreless is the way to go. If more power and the cogging side effects of magnetic core designs are acceptable, then using a ferrite or silicon steel core design is the best choice. Speaking of core materials, our designs use much less core material due to unique windings.
