N2 - In this paper, a method for deriving the rotor pole pair number of modular winding applied vernier motor is proposed. Unlike conventional permanent magnet synchronous motors, the pole-slot configuration of the vernier motor is determined by a fundamental vernier principle that is composed of the rotor pole pair, stator slot and stator winding pole pair numbers. However, when the modular winding is applied, the number of stator winding pole pair cannot be inferred intuitively, which leads to incomplete establishment of pole-slot combination of the vernier motor. Therefore, a method to derive the proper rotor pole pair number is proposed in this paper, which is developed based on the Fast Fourier Transformation of radial air-gap flux density. To verify the validity of the proposed method, it is applied to the vernier motor with conventional winding, and the results are compared to the number of rotor pole pairs derived using the fundamental vernier principle. Then, the verified method is applied to the vernier motor with modular windings for torque characteristics analysis. In addition, to verify that the adequate rotor pole pair number is derived, the results are compared with performance characteristics when incompatible rotor pole pair are applied.
