摘要：
According to the characteristics of high power density, high efficiency and high overload capacity of the yokeless and segmented armature (YASA) axial-flux permanent-magnet machine, the derivation formula of its size equation was put forward, and the magnetic network model was established in combination with its special magnetic circuit structure, and the motor was designed and analyzed. The stator module of the motor can be made of soft magnetic composite (SMC). This material is easy to be molded and has low eddy current loss under high frequency working conditions, which can further reduce iron consumption and improve operation efficiency and can be widely applied in electric traction drive especially in hub or wheel-rim drive of electric vehicle. Firstly, the main size equation of the motor was derived in order to determine the factors that affect the output power of the motor and design it initially. Then a simplified magnetic network model was established according to the path of the main flux flow of the motor, based on which, no-load electromotive force (EMF) and load torque can be easily acquired. The 3-D finite element method (FEM) calculation and experiment of the prototyped machine were implemented to verify the results from the simplified magnetic network modeling. © 2019, Harbin University of Science and Technology Publication.
