Benefits of Miba Radial Flux Motor

Icon Leistungsdichte
Highest power density with minimum installation space

With Miba LapWinding® we have designed a unique winding scheme. Hairpin design and its impact on the winding process when assembling a radial flux motor is one of Miba's core competencies. Thanks to many years of development work, we are able to optimise tolerances. This results in reduced winding head height and a high copper fill factor for superior power density.

Icon Hohe Dauerleistung
High continuous power with innovative cooling concepts

Innovative cooling concepts enable our development teams to ensure stable thermal conditions.  As a result, our radial flux motors achieve continuous performance that comes close to peak power.

Icon optimized production processes
Optimized production processes for cost efficiency

In-depth know-how in industrialization and automation enable us to implement robust manufacturing processes. These lead to stable production with low scrap rates and high overall plant effectiveness. In this way, we ensure cost-optimized production of radial flux motors.

What characterizes a radial flux motor?

In a radial flux motor, the magnetic flux is generated circularly (in the radial direction). They have a significantly smaller volume of permanent magnets. This makes them more sustainable and less expensive. At the same time, it also makes them easier to install, compared to other motor variants. 


Magnetic flux and winding resistance are kept short by using concentrated windings. Losses can thus be minimized. High torque results from the distance from the center of rotation of the motor to the air gap, where tangential forces are generated. Radial flux motors are characterized by greater torque due to this increased distance.


Another advantage is the increased power density. To achieve this, however, efficient heat dissipation from inside the motor is necessary. Here, Miba offers comprehensive know-how and advice on innovative cooling concepts for both stator and rotor cooling.
