The invention relates to an electric control permanent magnetic absorption device. The electric control permanent magnetic absorption device comprises a shaft system 1, a fixed disc 2, a magnetic system 3, a driving device 4 and a rotating disc 5, wherein the shaft system mainly consists of a fixed shaft and a fastening device; the fixed disc mainly consists of a disc shell and a buffer pad; the magnetic system mainly consists of a permanent magnet and a silicon steel chip body; and the driving device mainly consists of an electric wire and a magnetic yoke. The fixed disc is fixed on the shaft system; the driving device drives the rotating disc to rotate by surrounding the fixed shaft; the magnetic system is fixed on the fixed disc and the rotating disc in a certain sequence; N and S magnetic poles are alternately distributed in the maximal radius place of the disc surface; the relative positions of the N and S poles of the magnetic system on the rotating disc and the fixed disc are changed through the rotation of the rotating disc; and magnetic metals to be absorbed are attracted and released by using principles that unlike poles attract each other and like poles repel each other. The absorption device comprehensively applies electric control and permanent magnetic absorption, and is mainly used for absorbing iron magnetic metals. The electric control permanent magnetic absorption device is economical and practical, uses the characteristics of permanent magnets, and is safe and reliable.
