Axial Flux Motor Air-Core Coil - Project Details

In axial flux motors (also known as disc motors), the direction of the magnetic field is parallel to the motor shaft—a characteristic that distinguishes them from traditional radial flux motors. They are particularly well-suited for applications requiring high power density, high efficiency, and high dynamic performance.

Coil Features

High Efficiency: Eliminates core losses (eddy current and hysteresis losses); optimized for high-frequency applications.

Lightweight Design: Coreless structure significantly reduces weight, enabling superior power density.

Rapid Response: Low inductance allows for ultra-fast current transitions and excellent dynamic performance.

Superior Thermal Management: Direct contact between the coil and cooling medium ensures low thermal resistance and short heat dissipation paths.

Specifications

Inductance (L): Determined by the number of turns, diameter, and winding methodology.

DC Resistance (DCR): A key factor influencing power loss and efficiency.

Self-Resonant Frequency (SRF): The critical frequency beyond which the coil exhibits capacitive behavior.

Quality Factor (Q): Measures the ratio of energy storage to dissipation, essential for high-frequency performance.
