<p>PROBLEM TO BE SOLVED: To provide a less expensive spindle motor by reducing the manufacturing cost. SOLUTION: The spindle motor 1 is constituted so as to support a pivot 5 of a rotor 3 by a pair of open bearing 2. By using the open bearing 2 of simple constitution and low cost, in this constitution, manufacturing cost can be reduced, as compared with the conventional spindle motors using a pair of ball bearings with shield, and can provide the less expensive spindle motor 1.</p> |
