A proposal of consequent-pole type bearingless vernier motor

This paper presents a consequent pole type bearingless vernier motor which can generate high torque at low rotational speed without mechanical contacts. The conventional bearingless motor is suitable for rotating at high speed. However it is not suitable for generating high torque. Vernier motor have a particular structure. Because of that, it gets the high torque at low speed without gears. Thus, to combine bearingless motor with consequent pole type vernier motor, the proposed motor can generate high torque at low speed without any mechanical contacts. In this paper, the torque equation and the suspension force equation is shown. In addition to that, the theory and the analysis results are compared.
