A bearingless motor can be driven without any mechanical contact, thus, it offers the advantages of high mechanical durability, no material wear, and high speed drive. To realize non-contact suspension, a rotor should be magnetically stabilized in five (three-translational and two-tilting) degrees of freedom (DOF). Various types of bearingless motors with active regulation of two- to five-DOF have been developed. However, an increase in the number of actively controlled DOF causes an increase… CONTINUE READING
