Our precision aluminum stator housings are manufactured on German Hermle 5-axis machining centers, engineered for electric motor applications that demand complex geometric structures, tight dimensional tolerances and excellent thermal performance. The integrated finned stator ring design combines structural rigidity with optimized heat dissipation, making it ideal for high-performance drive motors and precision motion systems.
By completing all multi-surface milling, drilling, tapping and contour machining in a single clamping setup, we eliminate cumulative positioning errors from secondary fixturing, ensuring perfect concentricity, perpendicularity and positional accuracy across every feature. We support full customization from prototype validation to high-volume production, serving new energy automotive, industrial automation and aerospace clients worldwide.

Each stator housing is fully machined on a Hermle 5-axis machine in a single setup, producing complex radial fin structures, angled mounting faces, precision bore surfaces and distributed threaded holes in one continuous process. This one-clamp approach guarantees perfect alignment between the inner stator bore, mounting flange and cooling fin arrays, a level of geometric integrity that cannot be reliably achieved with conventional 3-axis machining and multiple re-fixturing.
The integrated finned structure is designed to maximize surface area for passive heat dissipation, drawing heat away from the stator winding and maintaining stable operating temperatures for extended motor life. High-grade aluminum alloy delivers an excellent strength-to-weight ratio, reducing overall motor mass while maintaining structural rigidity under dynamic operating loads.
All mounting holes are precision drilled and tapped with consistent thread depth and pitch accuracy, ensuring uniform clamping force and reliable assembly. All edges and corners receive light deburring to remove sharp burrs and break edges, with no cosmetic brushing applied to functional surfaces to preserve critical dimensional accuracy. Our engineering team provides DFM feedback tailored to stator housing design, helping optimize wall thickness, fin geometry and hole placement for improved manufacturability and performance.
Produced entirely on German Hermle 5-axis machining centers, all surfaces, angled features and threaded holes are completed in a single clamping. This eliminates repositioning errors and delivers exceptional concentricity, perpendicularity and positional accuracy that meets and exceeds premium motor industry standards.
The integrated radial fin structure maximizes heat transfer surface area without adding excessive weight. High thermal conductivity aluminum efficiently dissipates winding heat, reducing peak operating temperatures and improving motor reliability and service life.
High-grade aluminum alloy delivers outstanding strength-to-weight ratio compared to steel or cast iron alternatives. This reduces overall motor assembly weight, making it ideal for mobile applications such as electric vehicles and robotic systems where mass optimization is critical.
Single-setup 5-axis machining eliminates process variation caused by multiple fixturing and machine transfers. Every stator housing is produced with identical tool paths and process parameters, ensuring interchangeability and consistent performance across production volumes.
We work directly with your engineering team to optimize stator housing design for manufacturability. From prototype iteration to production scaling, we provide DFM feedback, material selection guidance and process optimization to reduce cost and improve performance.
