This paper presents the evolution of an airliner fan BLDC motor to adapt it to an HVDC electrical network. The guiding principle of the design is to increase reliability. A non-overlapping teeth winding is introduced to separate the motor phases in order to limit winding failures and especially partial discharges. The machine is also optimised using spoke-type magnets flux concentration rotor, in order to reduce total mass. The new machine is compared to the existing one with a finite elements method analysis.
