Abstract: This paper proposes a double consequent pole changing vernier machine (DCPCVM) which adopts double consequent pole and flux modulation configuration. The proposed machine combines a vernier machine and a permanent magnet synchronous machine (PMSM) in a single topology. Therefore, the advantages of both machines can be realized in a single topology. The proposed machine provides high torque at low speed while operating in vernier mode whereas it operates in PMSM mode at high speed to avoid the disadvantages of vernier machines at high speeds such as high core losses. Parametric analysis of the proposed machine is performed to show the effect of the main variables on the electromagnetic characteristics of the machine. A finite element method (FEM) analysis is conducted, and meaningful conclusions are drawn.
