Abstract

This paper proposes a dual rotor halbach array permanent magnet vernier machine (DRHAVM). Proposed vernier machine demonstrate high power factor with high torque density at low speed which is promising for low speed transportation applications. Proposed permanent magnet vernier machine structure omits necessity of gearbox and directly convert energy to low speed rotation. A comprehensive FEA of proposed DRHAVM including sensitivity analysis, back-EMF, torque density, torque per magnet volume, power factor, core loss, copper loss and efficiency are performed. Additionally, a detailed comparison is conducted between proposed DRHAVM and other types of Vernier machines in the literature. Results display that proposed halbach array vernier machine structure can achieve an appropriate power factor (0.84) and generate higher torque (2850 Nm) at speed rotation of 30 rpm.
