ABSTRACT:
A magnetic suspension bearing includes a plurality of magnets enclosed in an outer and an inner enclosure respectively. These magnets are disposed staggeringly up and down remaining a gap between each pair of magnets so as to generate a magnetic suspension force produced form repulsion force between magnets of the same polarity. With this magnetic suspension bearing the shaft is able to rotate with high speed yet less generation of heat loss by friction to improve the durability of the bearing compared with a conventional pivot or ball baring.
