永久磁石型ベアリングレスバーニアモータにおける永久磁石と電動機巻線の極数の検討

抄録

　Conventional motors usually have bearings and gears, which have many problems such as metal powder occurred by abrasion and lubrication oil. Bearingless motor solve the problems because it has no mechanical contacts. It is often used in an application which need high speed rotating. However, it cannot generate high torque at low speed because of no gears. Recently, there are bearingless vernier motor which is new type bearingless motor applied technique of magnetic levitation on vernier motors. It can generate high torque at low speed. Reluctance type bearingless vernier motor has already been proposed in our laboratory. Consequent pole type bearingless vernier motor is proposed and whether it can generate torque and suspension force in the same way as conventional consequent pole type bearingless motor is investigated.
