The invention relates to the technical field of machinery, in particular to a stator and rotor epoxy sealing process of a disc-type magnetic power generator. A stator and a rotor are respectively sealed to form two independent modules, and vacuum casting and high-temperature curing are employed. With regard to the characteristics of small size and compact space structure of the disc-type magnetic power generator, a high-temperature resistant epoxy sealing material is employed, the stator and the rotor are respectively sealed to form the two independent modules, thereby being beneficial for long-term working; and a member is difficult to fall off and wear, the insulation strength of a winding is also greatly improved, the disc-type magnetic power generator also has performance of corrosion prevention and oxidization resistance, so that the lifetime of a motor is prolonged.
