Large passive bearings of rotary machine tools and rotary machine tools, including generator sets

摘要

A passive magnetic bearing (PMB) for rotating machine tools is set to withstand the dimensional forces applicable to the three states when deployed in an operational environment with external forces. PMB consists of the first element of the ring with Halbach matrix. The second element DThere are first and second Halbach matrices on the ring The magnetic interaction of Halbach matrix defines a composite strength curve, which may contain an axial component which coincides with the axial force curve of the target, and contains a radiation component that matches the radiation force of the target.
