Radial Force Analysis of Radial Laminated Magnetic-Barrier Rotor Brushless Doubly-Fed Machine

Abstract:

In this paper, the respective harmonic magnetic field generated by the two sets of stator windings of radial laminated magnetic-barrier rotor brushless doubly-fed machine has been analyzed with the winding function method, the calculations of the radial forces on stator’s inner edge which are resulted from the fundamental and harmonic magnetic field that generated by the two sets of stator windings have been made, and the radial forces of three kinds of such machines with different rotor pole numbers have been compared, all the above can provide theoretical guidance for optimized design of radial laminated magnetic-barrier rotor brushless doubly-fed machine.
