The disclosure provides a stator module and a magnetic field generating structure which includes a magnetizer and an electrically conducting pipe. The electrically conducting pipe is wound around the magnetizer and has a passage inside. The passage has an outlet and an inlet opposite to each other. The electrically conducting pipe has a current input portion and a current output portion.

Stator module and magnetic field generating structure thereof

A magnetic repulsion-actuated magnetic bearing is constructed to include a stator, two magnetic repulsion modules mounted inside the stator, a rotor having two annular permanent magnets at the ends corresponding to the two magnetic repulsion modules. A magnetic force of repulsion is produced between equiangularly spaced permanent magnets of the magnetic repulsion modules and the annular permanent magnets of the rotor to keep the rotor radially in position automatically upon power failure. A controller is electrically connected to windings of the magnetic repulsion modules for controlling the current of the windings to change the intensity of magnetic force so as to further control the radial magnetic force of repulsion of the magnetic repulsion actuators, keeping the radial bearing stiffness during rotation of the rotor.
