ABSTRACT:
A method is for forming an oil-repellent film on a metallic part in a dynamic fluid pressure bearing mechanism used for a motor. The method includes applying a flowable oil-repellent agent on an application region of the metallic part; arranging an induction coil in the vicinity of the metallic part; and affixing the oil-repellent agent onto the metallic part by applying an induction heating to the metallic part by supplying an AC current with a frequency of about 5 to 100 kHz to the induction coil. Further, a motor includes a dynamic fluid pressure bearing mechanism including a metallic part on which an oil-repellent film is formed by the above method; a stator unit; and a rotor unit supported by the dynamic fluid pressure bearing mechanism in a manner rotatable with respect to the stator unit.
