When people first talk about axial-flux motors, many think of "expensive" — their signature high torque density relies on rare-earth permanent magnets with high heat resistance and high energy product, so any fluctuation in rare-earth prices makes procurement nervous. That is a fact, but not the whole story. Calculate the cost at the system level and the conclusion reverses. Axial-flux motors output torque efficiently: to reach the same torque they typically use less magnet and copper than radial motors, and their short windings save on costly oxygen-free copper. Using fewer materials is itself a cost advantage.
More critically, at the system level. Once torque density rises, some solutions can eliminate the gearbox or reduce battery capacity reserve, and the money saved often exceeds the premium on the motor itself. For a complete powertrain, the motor is just one piece of the BOM; the account must be looked at as a whole.
So "cost per unit torque" is the fairer yardstick. Looking only at the motor's price tag, axial flux is indeed not cheap; looking at the BOM of the whole powertrain, it does not necessarily lose — and in some lightweight-sensitive scenarios it is even more cost-effective. Moreover, as supporting components such as soft magnetic composites and SiC devices mature and scale, the manufacturing cost of axial flux itself is coming down. Cost is a matter of materials in the short term and of volume in the long term; any new motor has its price pushed down bit by bit during the mass-production ramp.
When helping customers evaluate automated assembly lines for axial-flux motors, Jiuju is also used to shifting the discussion from "how much does this motor cost" to "how much does the whole system save" — once the cost account is complete, many hesitations find their answer. Of course, selection ultimately depends on the application; cost advantages and scenarios are bound together.

The shipping area outside the workshop was a hive of activity. After multiple rounds of full-machine commissioning, simulated mass-production validation, and factory quality inspection, a Jiuju DC motor automatic assembly line completed all factory-out procedures, was loaded onto trucks on schedule, and is about to depart for the customer's production base, helping the customer's project advance production implementation on plan.
While new energy vehicles and robots are stealing the spotlight, industrial applications such as elevator traction machines, fans, and water pumps are quietly adopting axial flux motors. Here, the focus isn’t on flashy specifications, but on electricity bills and reliability at scale.

Magnetic flux must pass axially through the disc-shaped stator; traditional lamination stacking fails, and grain-oriented silicon steel ring-milled with slots destroys grain orientation. The stator and windings become the hardest nut to crack in axial flux mass production.

There is no universal architecture in engineering. Axial flux is more suitable for space-sensitive, lightweight-first scenarios; the radial motor remains the first choice for cost-sensitive, high-volume scenarios. The essence of selection is the degree of match with the application scenario.
