Design and Control of an Axial-Flux Machine for a Wide Flux-Weakening Operation Region

  title={Design and Control of an Axial-Flux Machine for a Wide Flux-Weakening Operation Region},
  author={Tae-suk Kwon and Seung-Ki Sul and Luigi Alberti and Nicola Bianchi},
  journal={IEEE Transactions on Industry Applications},
This paper describes the strategy to design and control an axial-flux (AxF) surface-mounted permanent-magnet machine for achieving a wide flux-weakening (FW) operating region. By using a slotted stator with fractional-slot windings and additional cores enclosing end windings, the AxF machine satisfies the specification of a wide constant-power speed range. The design procedure is presented for increasing FW capability while obtaining low-harmonic back electromotive force and low cogging torque… CONTINUE READING
