Abstract:DC excited doubly salient variable reluctance machine has received more attention due to its robust rotor structure, low cost and permanent magnet-free. In this paper, a short-pitch distributed winding connection with improved fifth order harmonic is newly applied in this kind of machine to enhance the torque production under the same current excitation. Its electromagnetic performance is analyzed by finite element analysis. The simulation results verify that compared with the traditional concentrated winding … Show more
