Abstract:
Motors having a magnetic force attenuator are described. In some embodiments, the motors comprise a stationary member having a base and a stator, a rotating assembly having a magnet and a magnetic force attenuator to attenuate the magnetic attraction force between the magnet and the base; and a fluid bearing to support rotation of the rotating assembly relative to the stationary member. The magnetic force attenuator typically comprises a material of high magnetic permeability, and modulates the magnetic attraction force between the magnet and the base of the motor.
