An axial flux motor stator is the stationary laminated core of an axial flux motor where magnetic flux flows parallel to the rotational axis (rather than radially, as in traditional motors). This creates a flat, disc-shaped "pancake" structure that dramatically reduces motor length while increasing torque density. The stator comprises coil elements arranged on a circle, each containing one or more windings and terminal contacts to supply current and generate a magnetic field in the axial direction for interaction with the rotor.

Reenives manufactures precision axial flux motor stator cores using non-oriented silicon steel (0.20–0.35mm) or soft magnetic composites (SMC), with advanced C5 epoxy coating — achieving core loss ≤9.5 W/kg @400Hz and stacking factor ≥98%.

Reenives offers axial flux motor stator solutions across multiple topologies to meet diverse application requirements:

• By Architecture: Single-sided stator (simplest), double-sided stator (dual-rotor, highest torque density), multi-stator (multiple stages for extreme power).
• By Material Technology: Laminated silicon steel (0.20/0.27/0.35mm, ideal for high frequency >1kHz) and Soft Magnetic Composite (SMC) (3D isotropic flux, complex shapes).
• By Core Type: Monolithic (one-piece stamped core, high structural integrity) and segmented (modular, easier winding) — segmented designs allow separate production of bottom plate, stator teeth, and magnetic conduction blocks for improved manufacturability.
• By Cooling Configuration: Integrated cooling cavities with radial passages for direct stator cooling — as implemented in Xiaomi EV's axial flux motor design.
• By Coating: C5 epoxy powder coating (Class H, 180°C) with ≥1800V dielectric; C6 varnish for high-voltage EV applications.

💡 Reenives specialty: Yokeless segmented armature (YASA) stator design — eliminating stator yoke reduces weight and iron loss, achieving up to 10 kW/kg power density. Available in 80–400mm OD with custom tooth geometries.

Reenives axial flux motor stator cores power critical applications across multiple sectors:

• UAV Propulsion & Drones: Ultra-light axial motors for racing, cinematic, and agricultural drones (60–250mm stator OD). Achieves up to +20% flight time over conventional radial designs.
• eVTOL Lift Fans: Double-sided axial configurations with high power-to-weight ratio for vertical takeoff and landing aircraft.
• Electric Vehicles: Axial flux motors with integrated cooling cavities — Xiaomi EV's design uses radial passages in the stator core to enable direct coolant circulation for improved heat dissipation.
• Robotic Actuators & Joints: Pancake shape fits tight spaces, low cogging torque for precision motion control.
• Renewable Energy Systems: Wind and solar generators where compact design and high efficiency are essential.

1. Define outer/inner diameter and axial length: Based on available mounting space and torque/power targets. OD 80–400mm standard; custom up to 550mm.
2. Choose material technology: Laminated silicon steel for high RPM (>12,000 RPM) and high-frequency operation; SMC for complex 3D flux paths and integrated cooling channels.
3. Select lamination thickness: 0.20mm for >20kHz switching frequency; 0.27mm for general UAV/eVTOL use; 0.35mm for cost-optimized industrial applications.
4. Determine core segmentation: Segmented for easier winding (manual/automated) or monolithic for maximum structural integrity and thermal performance. Segmented designs also enable independent production of stator teeth and magnetic conduction blocks for improved manufacturability.
5. Specify cooling and thermal management: Consider integrated cooling cavities with radial passages for high-power applications, as demonstrated in Xiaomi EV's axial flux motor.
