BEARING SYSTEM AND SPINDLE MOTOR ASSEMBLY THEREBY

摘要

PURPOSE: A bearing system is provided to easily manufacture and process the system and to support a body of revolution to extremely stabilize the body. CONSTITUTION: The bearing system includes:a lower base(100) having a fixing shaft(200); a cylindrical body(500) penetrating the fixing shaft(200); a first and a second magnetic body(601, 602) installed on the upper and the lower area of the cylindrical body(500); a third magnetic body(603) having a magnetic pole which is different from the polarity of the facing surface of the second magnetic body(602) formed on the surface facing the second magnetic body(602); a fourth magnetic body(604) having a magnetic pole which is different from the polarity of the facing surface of the first magnetic body(601) formed on the surface facing the first magnetic body(601); and an upper base fixing the fourth magnetic body(604).
