Title:
THRUST MAGNETIC BEARING AND FLYWHEEL BATTERY DEVICE
Document Type and Number:
Japanese Patent JP2002122139
Kind Code:
A
Abstract:
To miniaturize an iron core for electromagnet and reduce the weight thereof, and to enlarge a coil housing volume without reducing a necessary magnetic path area.
In a thrust magnetic bearing for supporting a rotor without contact therewith, resisting the axial directional thrust, thickness of an iron core 42 for electromagnet is formed so as to be gradually reduced toward outside in the radial direction. Namely, inner surfaces 53A and 52aA of a back side magnetic path 53 and an inward magnetic path 52a are respectively formed into a tapered surface coming closer to outer surfaces 53A and 52aB as they are directed toward outside in the radial direction.
