Global and U.S. Radial Flux Permanent Magnet Motors​ Market Report, Published by QY Research.

Radial Flux Permanent Magnet Motors (RFPMs) are high-efficiency electric machines in which magnetic flux flows radially through the air gap between the stator and rotor, offering strong torque density and compact structure. They are available in different cooling methods: air-cooled types use airflow or fans for heat dissipation and are common in low-to-medium power systems; liquid-cooled versions employ water-glycol or similar coolants for better thermal management in higher power or continuous-duty applications; and oil-cooled models use lubricating oil for both cooling and component lubrication, suitable for sealed or high-torque environments. Based on power range, low-power RFPMs (200 kW) serve heavy-duty electric trucks, aircraft propulsion, and wind turbines requiring superior thermal control and torque performance.
