The invention provides a double-permanent-magnet high-speed bidirectional electromagnet. The high-speed bidirectional electromagnet comprises two permanent-magnet high-speed electromagnets, wherein each permanent-magnet high-speed electromagnet comprises an iron core, a coil and an outer shell, the iron core comprises a cylindrical main magnetic pole and a circular auxiliary magnetic pole, a coil installation groove is arranged between the main magnetic pole and the auxiliary magnetic pole, the coil is arranged in the coil installation groove, the outer shell sleeves the iron core, the bottom of the main magnetic pole or the auxiliary magnetic pole is provided with an annular flange in an extension way, the permanent-magnet high-speed electromagnet also comprises an annular permanent magnet, the permanent magnet is embedded in the middle between the annular flange and the main magnetic pole or the auxiliary magnetic pole, the permanent magnet is in radial radiation magnetization, the two permanent-magnet high-speed electromagnets are symmetrically arranged, the permanent magnet ends of the two permanent-magnet high-speed electromagnets are opposite to each other, the two permanent-magnet high-speed electromagnets share an armature and a valve rod, the middle part of the main magnetic pole is provided with a through hole, the valve rod passes through the through hole, and the armature is fixed on the valve rod. The double-permanent-magnet high-speed bidirectional electromagnet provided by the invention has the advantages of fast response speed, small driving current, long service lifetime and high reliability, can move in a bidirectional way, and is suitably used for an electronically-controlled fuel system of a diesel engine.
