Abstract
Disclosed are a magnetic bearing and a centrifugal compressor. The magnetic bearing comprises a revolving shaft () and an electromagnetic component, wherein the electromagnetic component is arranged around an outer periphery of the revolving shaft (), and a gap is formed between the electromagnetic component and the revolving shaft () for adjusting a position of the revolving shaft (). The electromagnetic component comprises an iron core () with a winding slot, and coils (). The coils () are arranged in the winding slot. The magnetic bearing () also comprises a protection mechanism (), which is configured to prevent the revolving shaft () from colliding with the electromagnetic component, thereby achieving the purpose of axially protecting the magnetic bearing (). The centrifugal compressor comprises the magnetic bearing (), thereby obtaining axial protection and prolonging service life.
