摘要
PURPOSE: An END-magnet magnetic absorber using leakage flux is provided to rotate a rotating magnet smoothly and to prevent the exfoliation of the oxidant film coated onto the surface of an END-magnet by applying grease onto the surface of the END-magnet and a magnetic member in a weak magnetic portion and dried grease to a strong magnetic portion. CONSTITUTION: A non-magnetic spacer and a non-magnetic rotor(4) are fitted in between a front and rear magnetic members(2) interposed with a non-magnetic body(2-1). Rotating END-magnets(5) having a polarity different from that of a static END-magnet(5a) are fitted in the left and right sides of a shaft support bar of the rotor. One side of the rotating END-magnet fitted in the side A is a weak magnetic portion(5-2), while the other side is a strong magnetic portion(5-1). One side of the rotating END-magnet fitted in the side A' is a strong magnetic portion(5-1), while the other side is a weak magnetic portion(5-2). A grease chamber(5-2a) is formed between the circumferences of the weak magnetic portion and the magnetic member. The grease in the grease chamber is applied onto the surface of the rotating END-magnet and front and rear magnetic members. The grease on the rotating END-magnet and the magnetic members are pasted onto in the strong magnetic portion.
