Slotless Stator
- Zero Cogging Torque: Smooth magnetic air gap eliminates detent force for uninterrupted motion.
- Low Inductance: Enables fast current response in servo and BLDC systems.
- Compact and Lightweight: Simplified structure ideal for miniaturized high-speed motors.
- Excellent Thermal Dissipation: Short magnetic path and open winding structure enhance cooling.
- Low Iron Loss: ≤ 1.8 W/kg @ 50 Hz for high-efficiency operation.
- Flexible Coil Design: Compatible with pre-formed, litz, or flat wire winding.
