This paper investigates the opportunity of making a natural convection permanent magnet motor for an airliner high lift actuator. The motor is designed to have a maximum lifespan and reliability: removing liquid or forced air cooling removes a fault source. A winding with fully segregated phases is chosen to minimize phase-to-phase winding faults due to partial discharges that may appear at low pressures (high altitudes). A thermal analysis of the power that can be dissipated by natural convection and radiation is conducted. A two-pole surface-mounted permanent magnet motor is finally designed and optimized with a finite elements method analysis, leading to a motor ten times longer than its forced air cooling counterpart.
