Abstract

In the industrial field, the drive system integrated the high speed motor and the gear is required to effectively utilize the limited space. However, mechanical gears often require their lubrication and cooling, they generate whilst noise and vibration. To overcome these problems, the magnetic gears have been expected. Magnetic gears achieve the system with maintenance-free, low noise and low vibration characteristics by contact-less power transformation. However, conventional magnetic gears are not suitable system for high speed motors because the mechanical strength is weak due to permanent magnets of the high speed rotor. Adding that, the magnet eddy current loss in the high speed rotor seriously decreases the gear efficiency in high speed drive. This paper presents a novel reluctance magnetic gear for the super high speed motor. The high speed rotor of the proposed magnetic gear is constructed by only iron core. Therefore, the structure is very simple and robust and it is possible to rotate in the high speed region. Moreover, the magnetic gear achieves high efficiency in the high speed region because the magnet eddy current loss in the high speed rotor is not generated because of having no magnets. The downsizing of the system and high efficiency power transfer are realized by applying the reluctance magnetic gear.
