Radial force comparison of radial laminated magnetic-barrier rotor brushless doubly-fed machine with different rotor pole numbers

In this paper, take the 150kW radial laminated magnetic-barrier rotor brushless doubly-fed machine as an example, the unit area radial force of its rotor has been calculated theoretically by the winding method, the comparison of radial forces of different rotor pole-pair (odd and even) have been realized by theoretical calculation and FEM simulation calculation that based on Ansoft software, two operations (static state and synchronization operation) have been adopted in the FEM simulation, all the above can provide theoretical guidance for the optimized design of radial laminated magnetic-barrier rotor brushless doubly-fed machine as well as the vibration and noise research.
