Tóm tắt

This paper describes an analytical model of a single stage of a series- connected multi- stage coaxial magnetic gear (MSMG). This model is a system of spring-mass-dampers which is then used to investigate the vibrational modes and natural frequencies of the system at the rotational speeds observed during operation. This approach includes the bending and shear forces created in the magnetically active area of the gearbox which are generated due to the relative motion of the magnets that in turn produce fluctuating magnetic fields. Understanding these vibrational modes is important for magnetic gearboxes to realize their potential for long duration, low maintenance operation.
