A magnetic lifting machine according to the present invention is to prevent an antioxidant film on the surface of neodymium magnets from exfoliation, by having the neodymium magnets not be in direct contact with a pair of polarity plates of the machine but via anti-exfoliation plates made of non-magnetic material. The anti-exfoliation plates are fitted to both sides of a rotor containing the neodymium magnets therein between the polarity plates, and each of the anti-exfoliation plates may include a plurality of holes for oil storage radially therethrough.
