What is an Axial Flux Motor?
An axial flux motor, or disc motor, features a rotor and stator that align along the same axis. This design
makes the motor flat and compact.
It is smaller than traditional radial flux motors. In those motors, the rotor spins inside the stator. The unique
construction of axial flux motors enables them to achieve higher power density while being lightweight
and efficient. These flat motors are becoming popular. They are great for industries that need compact,
powerful, and energy-efficient solutions. Electric motorcycles, electric vehicles (EVs), airport pods, and
electric aircraft are key uses for these motors. However, manufacturing these motors at scale presents
challenges, particularly in stator coil winding, where precision and automation are essential.
The Difference Between Axial Flux Motors and Radial Flux Motors
A common question is, "What is the difference between an axial flux motor and a radial flux motor?"
Radial flux motors are a common design. In these motors, the magnetic field moves from the center of
the rotor to the outer edge of the stator.
This motor has a cylindrical shape. The rotor is inside the stator. This design makes it good for many
common uses.
On the other hand, axial flux motors have a disc-like design with the rotor and stator arranged along
the same axis. This design provides more power in a smaller and lighter package. This makes it perfect for
electric motorcycles, aircraft, and drones.
The main difference is in how the magnetic flux is set up and the shape of the motor. This affects efficiency,
power-to-weight ratio, and cooling performance.
Radial flux motors are still more common. However, disc-shaped motors are becoming popular for special
uses where size and weight matter.
Challenges in Manufacturing Flat Electric Motors
Producing flat electric motors requires precision and specialized machinery to wind the stator coils and
ensure optimal motor performance. Due to their compact, flat structure, the stator winding process for
these motors is more complex than that of radial flux motors.
At Nide, we understand these challenges and offer automated solutions to streamline the production process.
The ND-ZRX01 Automatic Axial Flux Motor Stator Winding Machine is made to solve these problems. It helps
make flat motors more efficient. This advanced machine helps overcome the barriers to producing
high-performance disc motors at scale.

Nide's Automatic Axial Flux Motor Stator Winding Machine (ND-ZRX01) automates the winding of
disc-shaped motor stators. This greatly improves production speed and accuracy. The machine operates
with a single station that combines manual loading with automatic clamping to reduce labor intensity.
Key Features:
Servo Mechanism: Equipped with 2 servo motors for X/Y axis winding and 1 for Z-axis wire distribution.
The S-axis servo motor ensures precise indexing during the winding process.
High Precision: Electronic tension control and wire break detection work together. This ensures accurate
wire handling and the best coil tension.
You can change settings easily.
You can adjust the number of slots, turns, and winding speed.
This is done using the HMI interface. This allows for great flexibility in production.
Efficiency: The winding speed goes from 0 to 500 RPM, based on the wire size. The machine can handle
wire diameters from φ0.50 to φ1.5 mm. and stator outer diameters (φ150—φ450mm).
By automating the winding process, Nide helps manufacturers lower labor costs. This also speeds up
production and ensures consistent quality in flat electric motor stator parts.
Applications of Flat Electric Motors
Axial flux motors are particularly advantageous in compact and high-power applications. Their lightweight
design and high power make them ideal for industries where performance, size, and weight matter.
Key applications include:
Electric Motorcycles: These flat motors provide the perfect combination of power output and compact

Electric Vehicles (EVs): Disc-shaped motors have a high power-to-weight ratio. This helps electric cars
use energy more efficiently and improves battery life.
Electric Aircraft: The aviation industry gains from the lightweight design of axial flux motors. This makes
them perfect for electric aircraft and other aerospace technologies.
Delivery Trucks and Airport Pods
City transport is becoming electric. Flat motors are a good choice for this. They offer the right balance
of power and size. This makes them ideal for electric delivery trucks and airport transport pods.
Overcoming Manufacturing Hurdles in Flat Motor Production
Axial flux motors have many benefits. However, they are used less than radial flux motors. This is mainly
because their manufacturing process is more complex.
Winding the stators for these motors needs special equipment. This equipment ensures precision while
working with the motor's flat, compact design.
At Nide, we help manufacturers overcome these challenges with the ND-ZRX01 Automatic Stator Winding Machine.
This automated solution cuts down on manual work. It boosts production efficiency and ensures high-quality
stator parts for top-performing disc motors.
